Security TRM Labs: Senior / Staff Threat Intelligence Analyst, Hacks

Leads threat intelligence operations for blockchain hacks, coordinating incident response, analysis, and customer communications while building AI-powered detection systems.

Senior Posted about 4 hours ago We Work Remotely — Programming
What this role involves

Headquarters: United States
URL: https://www.trmlabs.com/

About the Role

When a protocol is drained, or an exchange is compromised, our customers need to know within minutes or hours which addresses to block and where the funds are going. You will own TRM's answer to that, end-to-end.

As a Senior / Staff Threat Intelligence Analyst, you will lead TRM's hacks category: the metrics, the system that hits them, and the small contractor team that keeps it running around the clock. We align on the outcome; the approach is yours.

The impact you will have

  • Take command when a big hack breaks and act as a leader. Run the response: triage, coordination across teams, internal and customer communications, and the incident report afterwards.

  • Get every major hack into TRM fast. Make sure every major hack is visible to customers within hours of the first credible public report, around the clock.

  • Keep TRM's hack data complete and accurate. Every hack, at any size, is recorded with its entity, theft addresses, date, amount, and hack type.

  • Follow the money at scale. Design the system, with our Data Science and engineering teams, that carries hack-specific attribution downstream as stolen funds move.

  • Build the machine with AI. Leverage AI to build the tools and agents to automate key parts of hacks analysis and response, while ensuring human quality control over every output.

  • Explain how it happened. Root-cause the most important hacks and publish best-in-industry technical analysis that makes TRM the first source cited.

  • See the next one coming. Build approaches that spot vulnerable contracts before they are exploited, and get them into our product.

What we're looking for

  • 5+ years of professional experience in blockchain intelligence, crypto investigations, cyber threat intelligence, incident response, or a closely related field.

  • Has owned incident response in a high-stakes environment (exchange, security firm, incident response, or CTI team): war rooms, incident reports, communications under pressure.

  • Strong blockchain tracing across major chains (BTC, EVM, TRON, Solana), including bridges, cross-chain swaps, and mixers.

  • Understands how DeFi, bridge, and exchange exploits work, and how attackers behave after the theft.

  • Applied AI fluency. We expect you to already be building AI-assisted or agentic workflows in your daily analytical work, to be able to show how you validate their outputs and where they fail, and to treat AI as a force multiplier.

  • Experience managing contractors or leading a small team.

  • Writes and briefs clearly, from technical deep-dives to executive summaries.

  • Hands-on and highly accountable: does the hardest work, not only coordinates it.

Nice to have

  • Smart-contract reverse-engineering (Solidity).

  • Experience at a security auditor or blockchain analytics firm.

  • Experience following specific well-known hacker groups.

About the Team

The hacks function sits within TRM's Primary Intelligence organization, alongside the Facilitation & Money Laundering (F&ML) pod. You will work closely with the Nation States, Cyber Threat Intelligence, and Global Investigations teams, as well as with Data Science and Engineering on automation, and with Marketing on publications.

Team Operating Rhythms

  • Monthly metrics review with your manager.

  • Weekly operating sync with your team.

  • Regular syncs with your team across time zones.

  • A war room, run by you, whenever a major hack breaks.

  • On-call responsibilities

Application Instructions

If you’re interested in joining TRM, we encourage you to apply directly. Every application is reviewed by our Talent team.

Before applying, review the job description carefully and highlight the experience and impact that best demonstrate the required qualifications. Please also provide thoughtful and accurate answers to the application questions, as these will be used to evaluate your skills and qualifications for the role.

If you send your resume directly to someone at TRM, we can’t guarantee it will reach the appropriate hiring team. Applying directly is the best way to ensure your application will be considered.

Interviewing with TRM

Our process is designed to understand how you think, solve problems, and deliver impact, while allowing you to evaluate TRM. Most interview processes include a case study, an AI skills assessment, and a Leadership Principles interview.

  • Recruiter Intro: Qualifications, motivations, and alignment with the role.

  • Hiring Manager: Deep dive into your relevant experience, skills, and impact.

  • First Round: 1–2 interviews focused on the skills most critical to the role.

  • Final Round: Hands-on case study. This is usually a panel-style session where we go deeper into your craft, problem-solving, and alignment with TRM.

  • References: Former colleagues who can provide insight into your work and impact.

  • Offer: Congrats! Your recruiter will present the offer and compensation details.

  • Welcome to TRM: We're excited to build a safer world with you!

Your recruiter will share your specific interview plan and preparation guidance along the way.

AI Fluency at TRM

AI fluency is a baseline expectation at TRM.

We believe AI meaningfully changes how top performers operate. We expect every team member to use AI to accelerate and reimagine their craft, not just automate surface tasks.

At TRM, AI fluency means you are among the top 10 percent of operators in your function in how you apply AI to:

  • Accelerate repeatable workflows

  • Structure and solve problems

  • Improve output quality

  • Increase speed and leverage

You will be evaluated on applied AI fluency during the interview process.

Life at TRM

We are building a safer world. That promise shows up in how we work every day.

TRM moves FAST. We are a high-velocity, high-ownership team that expects clarity, follow-through, and impact. People who thrive here are energized by hard problems, experimentation, and continuous feedback. If something takes months elsewhere, it will ship here in days.

Our work sits at the intersection of AI, national security, and fighting crime. The problems are complex, the stakes are real, and the environment evolves quickly. The pace and intensity of the work reflect the importance of the mission. As a result, the way we operate requires a high level of ownership, adaptability, collaboration, and creative problem-solving.

At TRM, you should expect:

  • Priorities and targets to change quickly

  • Operating with a high degree of ambiguity

  • A high level of personal ownership and accountability

  • Close collaboration across teams and functions

  • Frequent, high-touch communication

  • Creative problem-solving and out-of-the-box thinking

  • A pace that rewards urgency, adaptability, and outcomes

This environment is energizing for people who enjoy building, solving hard problems, and making progress in situations that are not always fully defined. It also requires thriving in ambiguity, adjusting course as new information emerges, and maintaining focus and positivity in a fast-moving and intense environment.

We also recognize that this style of operating is not for everyone. If you are primarily optimizing for predictability or a consistently balanced workload, we encourage you to use the interview process to pressure-test whether this environment is truly the right fit. We want teammates who thrive here, not just survive here.

If you are excited by meaningful problems, motivated by ambitious goals, and energized by working alongside mission-driven colleagues, there is a good chance you will find TRM to be an exceptional place to grow and contribute.

Leadership Principles

We hire and grow against three leadership principles. They’re the standards for how we operate, treat each other, and make decisions.

  • Impact-Oriented Trailblazer: We put customers first and move with speed, focus, and adaptability. We treat every plan like an experiment – test, ship, measure, and iterate quickly.

  • Master Craftsperson: We care deeply about our craft. We balance speed with high standards, own outcomes end‑to‑end, and invest in getting better everyday.

  • Inspiring Colleague: We add clarity and energy, not noise. We bring humility, candor, and a one‑team mindset — giving and receiving feedback to make the team stronger.

Join our Mission

At TRM, we care deeply about our craft. We are looking for individuals who want their work to matter, who experiment with speed and rigor, and who take pride in building a safer world for billions of people. If you’re excited by TRM’s mission but don’t check every box, we encourage you to apply — we hire for slope, judgment, and the will to learn fast.

TRM is a Series C company with $220M in total funding, backed by Goldman Sachs, Bessemer, Y Combinator, Thoma Bravo, and others. Headquartered in San Francisco, TRM operates as a distributed-first company with hubs in Los Angeles, San Francisco, New York, Washington D.C., London, and Singapore.

Security Stripe: Abuse Research Engineer

Conducts proactive threat hunting, fraud kill-chain analysis, adversary research, and agentic simulations to identify and eliminate Stripe product vulnerabilities.

Senior Remote Posted 3 days ago We Work Remotely — Programming
What this role involves

Headquarters: Remote from the US

Who we are

About Stripe

Stripe is a financial infrastructure platform for businesses. Millions of companies—from the world’s largest enterprises to the most ambitious startups—use Stripe to accept payments, grow their revenue, and accelerate new business opportunities. Our mission is to increase the GDP of the internet, and we have a staggering amount of work ahead. That means you have an unprecedented opportunity to put the global economy within everyone’s reach while doing the most important work of your career.

About the team

Abuse Research Group (ARG) handles proactive threat hunting and adversary behavior analysis across Stripe products. Rather than reacting to alerts, the team maps end-to-end fraud and abuse paths, validates novel attack vectors, and identifies product conditions that enable fraud. Using agentic automated testing and simulation tools, ARG translates research into actionable threat advisories, strategic control recommendations, and regression scenarios to systematically eliminate vulnerabilities.

What you’ll do

As an Abuse Research Engineer in the Abuse Research Group, you will play a critical role in safeguarding Stripe’s financial ecosystem by proactively hunting for advanced threats, dissecting complex fraud vectors, and extracting actionable adversary intelligence.  Rather than relying solely on reactive alerts, you will develop and execute hypothesis-driven threat hunting operations across internal telemetry and external sources to uncover fraudulent tools, tactics, and techniques (TTPs) before they impact Stripe’s platform. Central to this work is FT3 (Fraud Taxonomy 3.0), Stripe’s multi-layered taxonomy that decomposes monolithic fraud into structured kill chains.  Collaborating cross-functionally with Fraud Ops, Strategy, Risk, Onboarding, and Security, you will integrate threat intelligence, build agentic simulation workflows, and systematically eliminate product vulnerabilities.

Responsibilities

  • Proactive Threat Hunting & Kill Chain Analysis: Formulate hypotheses and conduct iterative threat hunting operations across Stripe systems and external data.
  • FT3 Taxonomy: Apply and enrich the FT3 framework across empirical datasets and incidents, standardizing threat intelligence across kill chain phases and targeted API endpoints.  
  • Threat Intelligence & Signal Expansion: Partner with teams like Fraud Intelligence to integrate, curate, and automate threat feeds into engineering workflows.  
  • Cross-Functional Advisories & Strategic Controls: Translate raw research and retrospective findings into actionable threat advisories and control recommendations (policy, technical systems, support workflows, and detection mechanisms) for stakeholders across Fraud, Risk, Onboarding, and Security.  
  • Agentic Testing & Adversary Simulation: Utilize agentic automated testing frameworks to simulate adversary TTPs, validate whether deployed controls interrupt empirical kill chains, and generate regression scenarios to exercise controls.  

Who you are

We’re looking for someone who meets the minimum requirements to be considered for the role. If you meet these requirements, you are encouraged to apply. The preferred qualifications are a bonus, not a requirement.

Minimum requirements

  • 5+ years of experience conducting threat intelligence, threat hunting, or technical incident response within cyber security, product abuse, or trust domains.  
  • 5+ years of experience analyzing large, complex datasets using data analytics tools to identify anomalies, map behavioral trends, and solve complex fraud problems.  
  • B.S. or M.S. in Computer Science, Cybersecurity, or a related technical field, or equivalent practical experience.  
  • Expert proficiency in Python and SQL, with demonstrated experience using code and scripting to automate workflows, build investigative tools, or query big data pipelines.  
  • Hands-on experience in log analysis (e.g., application logs, API route telemetry, network security events), digital forensics, and cyber investigation methodologies.  
  • Strong communication skills with a proven ability to translate complex technical research into clear, actionable recommendations and advisories for cross-functional partners.

Preferred qualifications

  • Deep technical understanding of threat actor motivations, infrastructure, and TTPs specific to financial fraud (e.g., ATO, Card Testing, Credential Stuffing). 
  • Familiarity with standardized taxonomies such as FT3 or MITRE ATT&CK.  
  • Proficiency with engineering, data processing, and analysis platforms such as Databricks, Trino, PySpark, Pandas, or Scikit-Learn.  
  • Proven background utilizing Threat Intelligence Platforms (TIPs), tactical threat feeds, OSINT, and breach intelligence. 
  • Demonstrated capability building or leveraging agentic LLM tools, automated testing systems, or control validation frameworks to model adversary behavior at scale.  
  • Participation in industry conferences, webinars, or threat-sharing groups, alongside relevant professional certifications (e.g., GCTI, GCFA, OSCP).

This role is calibrated at the L6 senior-IC level: owning semi-annual or annual goals, solving ambiguous problems with sound judgment, improving operational processes, and driving meaningful cross-team collaboration and influence.

Key Responsibilities

Secure SDLC, design review, and threat modeling

  • Own and continuously improve the secure software development lifecycle for Apollo applications so security is embedded into design, implementation, and deployment.
  • Perform application security reviews, threat modeling, and deep code-level analysis for high-impact product, platform, and AI features before launch.
  • Provide practical security architecture guidance to Engineering, Product, and IT teams
  • Help define and maintain application-security guardrails, secure design expectations, code review standards, and risk models for new and existing systems.

Vulnerability management and hands-on remediation

  • Drive execution-heavy vulnerability management across internal reviews, bug bounty, pentests, SCA/runtime findings, and other research signals, ensuring findings are validated, prioritized, routed clearly, and tracked through remediation and verification within SLAs.
  • Go beyond identifying issues: read the code, explain root cause, propose the safest fix, and directly implement or support remediation when needed for complex vulnerabilities.
  • Perform hands-on validation and offensive security testing of applications and fixes, including exploit development, bypass testing, adversarial thinking, and focused red-team-style exercises, to confirm remediations address the underlying issue rather than only the initial symptom.
  • Work across the kinds of application security issues common in modern SaaS environments, including authentication and authorization weaknesses, access control risks, OAuth and CSRF design flaws, SSRF, cryptographic and verification issues, information disclosure and data exposure risks, unsafe execution and deserialization patterns, and dependency or runtime vulnerabilities.
  • Apply clear, risk-based severity decisions using exploitability, data sensitivity, customer impact, and blast radius

Tooling, automation, and AI

  • Configure and improve AppSec tooling and integrations, including SAST configuration, ignore lists, dashboards, and other controls that maintain useful coverage without excessive noise.
  • Select, build, or refine security tooling, small automations, and workflow enrichments that reduce manual effort and scale AppSec operations responsibly.
  • Use AI to automate, transform, and scale security and engineering-adjacent processes where it materially improves speed, consistency, or signal quality, while still validating outputs with strong engineering judgment.
  • Embed AI-specific security checks into SSDLC reviews and code analysis, including input and output handling, AI-exposed APIs, prompt and response guardrails, and abuse or data-exfiltration paths.
  • Partner cross-functionally on AI security requirements and controls so AI systems and AI-powered features are designed, deployed, and operated securely.

Engineering enablement and partnership

  • Support and scale security enablement for engineers and security champions, including secure coding, AppSec, and AI-safety content.
  • Provide actionable remediation guidance, secure patterns, and examples that help engineering teams fix issues quickly and correctly.
  • Partner closely with Engineering, Product, Platform, Data, Legal, and other security teams to keep AppSec priorities aligned with business risk and product velocity.
  • Produce clear documentation, metrics, and written narratives that improve AppSec visibility, observability, and decision-making.

What Good Looks Like

  • Owns meaningful AppSec goals over a semi-annual or annual horizon and independently identifies the right solutions to ambiguous, open-ended problems.
  • Drives cross-team collaboration and operational improvements beyond isolated tickets or one-off reviews
  • Makes informed decisions by balancing technical detail, business context, customer trust, and long-term risk
  • Sets a high bar for ownership, communication, mentoring, and technical judgment, and helps raise the effectiveness of peers and partner teams.

Required Skills & Experience

  • 5+ years of software engineering or application security experience, with meaningful hands-on AppSec depth in modern SaaS environments.
  • Strong software development skills and the ability to read, write, and ship production code; Ruby experience is highly valuable, and Python or similar scripting ability is a plus.
  • Strong Linux and cloud fundamentals, ideally with experience in GCP-backed environments.
  • Deep familiarity with common AppSec issues, secure design, secure authentication and authorization patterns, vulnerability management, and developer security tooling.
  • Demonstrated ability to perform deep code review, penetration testing, and exploit-oriented validation, and to either fix vulnerabilities directly or work closely with engineers to land durable remediations that hold up against bypass attempts and variant analysis.
  • Experience handling findings from bug bounty, pentests, internal reviews, or automated security tooling through closure and verification.
  • Experience using AI-assisted tools, automations, APIs, or structured workflows to improve engineering or security processes at scale.
  • Experience securing AI-powered systems or features, including AI API exposure, prompt and response handling, data protection, misuse scenarios, and monitoring expectations.
  • Strong written and verbal communication, stakeholder management, and influencing skills across technical and non-technical partners.

Preferred Qualifications

  • Experience supporting or leading security reviews for AI-native products, internal agents, or AI-assisted engineering workflows.
  • Experience improving secure-by-design practices and AppSec observability in a fast-moving engineering organization
  • Experience with security training, developer enablement, or security champions programs
  • Relevant security certifications are a plus

Example Success Outcomes

  • Improve the health and flow of AppSec findings by keeping prioritization, remediation, and verification moving within defined SLAs.
  • Complete recurring application reviews or threat models for important systems and features
  • Increase engineering adoption of secure patterns, AppSec tooling, and security training
  • Reduce manual toil and improve AppSec signal quality through targeted automation and responsible use of AI-assisted workflows.

Senior Remote Posted 5 days ago RemoteFirstJobs Product
What this role involves

Tines is the intelligent workflow company that powers some of the world’s most important workflows.

Tines has been supporting IT and security teams from a diverse range of customers, including Canva, Reddit, SAP, Coinbase, Mars, Fin (Intercom), and McKesson.

Tines 3B, launched in 2026, is the next generation of Tines – a single, secure environment for every team’s apps, agents and automations.

As an integrator across the entire tech stack, Tines is vendor-agnostic integrating with any API-enabled service. This flexibility enables our customers to achieve their highest-priority goals faster. Tines has security woven into its DNA, and our platform is secure and private by design.

At Tines, we’re driven by our values of Simplicity, Speed, and Soundness. We’re committed to delivering exceptional customer experiences while fostering a company culture that nurtures individual curiosity, growth, and integrity. We’re excited about what’s next, and we’re looking for others to join us on our journey.

Tines is seeking an experienced Senior Governance, Risk, and Compliance (GRC) Analyst to help execute and operate our compliance programs during a pivotal growth phase. Reporting to our Director of GRC, you will work across our commercial certifications — SOC 2 Type II and ISO 27001, 27701 and 42001 — and our FedRAMP program, while supporting vendor risk management and customer security assurance.

This is a hands-on execution role. You’ll partner with our Staff GRC Analysts, who set certification strategy, and own the operational delivery behind it: collecting evidence, testing controls, running audit cycles, assessing vendors, and answering the security questions our customers and prospects ask. You’ll also have a real mandate to automate the parts of this work that shouldn’t be manual, using Tines itself.

Location: Based remotely in the United States.

What you’ll be doing:

  • Certification and Audit Execution — Drive audit cycles end to end for SOC 2 Type II and ISO 27001 / 27701 / 42001: evidence collection, control testing, auditor liaison, and remediation tracking. Support gap assessments for net-new certifications we’re evaluating.
  • FedRAMP Program Support — Support our FedRAMP efforts, including gap analysis, remediation planning, documentation development, and coordination with 3PAO assessors.
  • Continuous Control Monitoring — Operate the year-round monitoring cadence that keeps certifications live between audits — scan and pen test reporting, control drift detection, and evidence freshness.
  • Vendor Risk Management — Run vendor security assessments, evaluating security controls and compliance posture before acquisition, and help mature our third-party risk program.
  • Risk Assessment and Management — Conduct risk analyses for systems, processes, and third-party applications, and implement appropriate controls to mitigate identified risks.
  • Customer Security Assurance — Respond to customer security inquiries, questionnaires, and audit requests, and support Sales on RFPs and RFQs. Keep our Trust Center documentation current.
  • Contract Review and Management — Partner with Legal to review contracts for security and compliance requirements, ensure appropriate security provisions are included, identify compliance risks and recommend mitigating controls. Help develop standardized security language for various contract types.
  • Compliance Automation — Use Tines to streamline compliance processes, evidence collection and reporting, and reduce the manual load on the team.
  • Policy Development and Maintenance — Review, update and develop security policies and procedures aligned with regulatory requirements and industry best practices.
  • Cross-functional Collaboration — Partner with Engineering, Product, IT, Legal, HR and leadership to embed compliance requirements into organizational processes.
  • Regulatory Monitoring — Stay current with evolving compliance standards and regulatory requirements relevant to our business and our customers.

What you bring with you:

  • 8-12 years of experience in IT compliance, security, or risk management
  • Hands-on experience implementing or maintaining ISO 27001 compliance
  • Strong knowledge of SOC 2 compliance frameworks and audit processes, including evidence collection and control testing
  • Experience supporting FedRAMP certification processes and requirements
  • Experience conducting vendor security assessments and risk analyses
  • Excellent understanding of information security principles, controls, and best practices
  • Strong project management skills, with the ability to manage multiple compliance initiatives simultaneously
  • Exceptional communication skills for translating technical requirements to non-technical stakeholders
  • Previous experience on the audit side — at a 3PAO or audit firm (e.g. Coalfire, Schellman, KPMG) — or driving gap remediation for certification readiness
  • Industry certifications such as CISSP, CISA, or CISM
  • Experience with compliance automation tools and techniques, or scripting/API experience for evidence automation
  • Continuous monitoring (ConMon) and compliance reporting experience
  • Knowledge of cloud security principles and controls (AWS, Azure, GCP)
  • Experience reviewing contracts for security and compliance requirements
  • Experience in SaaS or technology companies
  • Familiarity with privacy regulations (GDPR, CCPA)
  • Experience working in remote-first environments

Target Annual Compensation: $175,000-190,000

Applicants for this opportunity must be authorized to work for any employer in the U.S. We are unable to sponsor or take over sponsorship of an employment Visa at this time.

Reporting to our Director of GRC, you will work across our commercial certifications — SOC 2 Type II and ISO 27001, 27701 and 42001 — and our FedRAMP program, while supporting vendor risk management and customer security assurance.

This is a hands-on execution role. You’ll partner with our Staff GRC Analysts, who set certification strategy, and own the operational delivery behind it: collecting evidence, testing controls, running audit cycles, assessing vendors, and answering the security questions our customers and prospects ask. You’ll also have a real mandate to automate the parts of this work that shouldn’t be manual, using Tines itself.

Location: Based remotely in the United States.

What you’ll be doing:

  • Certification and Audit Execution — Drive audit cycles end to end for SOC 2 Type II and ISO 27001 / 27701 / 42001: evidence collection, control testing, auditor liaison, and remediation tracking. Support gap assessments for net-new certifications we’re evaluating.
  • FedRAMP Program Support — Support our FedRAMP efforts, including gap analysis, remediation planning, documentation development, and coordination with 3PAO assessors.
  • Continuous Control Monitoring — Operate the year-round monitoring cadence that keeps certifications live between audits — scan and pen test reporting, control drift detection, and evidence freshness.
  • Vendor Risk Management — Run vendor security assessments, evaluating security controls and compliance posture before acquisition, and help mature our third-party risk program.
  • Risk Assessment and Management — Conduct risk analyses for systems, processes, and third-party applications, and implement appropriate controls to mitigate identified risks.
  • Customer Security Assurance — Respond to customer security inquiries, questionnaires, and audit requests, and support Sales on RFPs and RFQs. Keep our Trust Center documentation current.
  • Contract Review and Management — Partner with Legal to review contracts for security and compliance requirements, ensure appropriate security provisions are included, identify compliance risks and recommend mitigating controls. Help develop standardized security language for various contract types.
  • Compliance Automation — Use Tines to streamline compliance processes, evidence collection and reporting, and reduce the manual load on the team.
  • Policy Development and Maintenance — Review, update and develop security policies and procedures aligned with regulatory requirements and industry best practices.
  • Cross-functional Collaboration — Partner with Engineering, Product, IT, Legal, HR and leadership to embed compliance requirements into organizational processes.
  • Regulatory Monitoring — Stay current with evolving compliance standards and regulatory requirements relevant to our business and our customers.

What you bring with you:

  • 8-12 years of experience in IT compliance, security, or risk management
  • Hands-on experience implementing or maintaining ISO 27001 compliance
  • Strong knowledge of SOC 2 compliance frameworks and audit processes, including evidence collection and control testing
  • Experience supporting FedRAMP certification processes and requirements
  • Experience conducting vendor security assessments and risk analyses
  • Excellent understanding of information security principles, controls, and best practices
  • Strong project management skills, with the ability to manage multiple compliance initiatives simultaneously
  • Exceptional communication skills for translating technical requirements to non-technical stakeholders
  • Previous experience on the audit side — at a 3PAO or audit firm (e.g. Coalfire, Schellman, KPMG) — or driving gap remediation for certification readiness
  • Industry certifications such as CISSP, CISA, or CISM
  • Experience with compliance automation tools and techniques, or scripting/API experience for evidence automation
  • Continuous monitoring (ConMon) and compliance reporting experience
  • Knowledge of cloud security principles and controls (AWS, Azure, GCP)
  • Experience reviewing contracts for security and compliance requirements
  • Experience in SaaS or technology companies
  • Familiarity with privacy regulations (GDPR, CCPA)
  • Experience working in remote-first environments

Target Annual Compensation: $175,000-190,000

Applicants for this opportunity must be authorized to work for any employer in the U.S. We are unable to sponsor or take over sponsorship of an employment Visa at this time.
