• Design, prototype, and deploy technical controls across API, protocol, and product boundaries to address high-impact abuse vectors.
• Translate empirical attacker evidence and FT3 threat research from Abuse Research, Fraud, and Security teams into precise technical abuse requirements and control specifications.
• Collaborate with teams across Stripe to design resilient, secure controls across payments, onboarding, identity, and Connect surfaces.
• Run rigorous experiments and A/B tests to measure risk reduction against the impact on legitimate user conversion, optimizing controls to minimize friction while neutralizing threats.
• Build comprehensive regression test suites and automated attack simulations with Abuse Research to ensure mitigated abuse vectors do not recur.
• Execute ACE’s incubation model by defining handoff criteria, operational documentation, timelines, and target dates for transferring successful controls to product teams.

• 10+ years of experience in security engineering, software engineering, application security, or anti-abuse engineering in a high-scale production environment.
• A bachelor’s or master’s degree in computer science, cybersecurity, software engineering, or a related technical field, or equivalent practical experience.
• A strong software development background, with proficiency in Python, Go, Java, or a similar production programming language, as well as advanced SQL skills for analyzing system telemetry.
• Experience using frontier AI models for software development, learning, and analysis.
• Hands-on experience building API-level safeguards, rate-limiting frameworks, authentication or authorization checks, or input-validation controls.
• Experience with automated testing frameworks, including writing unit, integration, and regression tests for critical backend software.
• Strong cross-functional collaboration and communication skills, with a track record of partnering across security, product, and platform teams to drive technical outcomes.
• Будет плюсом: A track record of designing and executing A/B tests, evaluating control efficacy, and balancing security safeguards against user conversion friction; Expertise in threat modeling, secure systems architecture, and modern application-security design principles; Familiarity with established threat frameworks, such as FT3 or MITRE ATT&CK, and experience applying adversary kill-chain analysis to build resilient defenses; Knowledge of financial fraud vectors, threat-actor tactics, techniques, and procedures, and attacker infrastructure, including account takeover, card testing, and credential stuffing; Hands-on experience with large-scale data-processing platforms, such as Databricks, Trino, or PySpark, to monitor and measure control performance across distributed systems; Experience incubating software features, establishing clear operational handoff criteria, and transitioning ownership to partner engineering teams

• This role is available either in an office or a remote location (35+ miles or 56+ km from a Stripe office).
• Office-assigned Stripes spend at least 50% of the time in a given month in their local office or with users. This hits a balance between bringing people together for in-person collaboration and learning from each other, while supporting flexibility about how to do this in a way that makes sense for individuals and their teams.
• A remote location is defined as being 35 miles (56 kilometers) or more from one of our offices. While you would be welcome to come into the office for team/business meetings, on-sites, meet-ups, and events, our expectation is you would regularly work from home rather than a Stripe office. Stripe does not cover the cost of relocating to a remote location. We encourage you to apply for roles that match the location where you currently live or plan to live.
• The annual salary range for this role in the primary location is €132,000 - €198,000. This range may change if you are hired in another location.
• Benefits/additional compensation for this role may include: equity, company bonus or sales commissions/bonuses; retirement plans; health benefits; and wellness stipends.
