Engineering Manager, Trust & Safety, Surveillance & Compliance

ABOUT POLYMARKET Polymarket is the world's largest prediction market. In the US, we operate a CFTC-regulated exchange and clearinghouse, which comes with real obligations to protect our markets and our users. We recently launched our Trust & Safety program and are building surveillance and compliance capabilities in-house. Engineering is the team that makes those commitments work in production. ABOUT THE ROLE We're hiring an Engineering Manager to lead the systems that keep Polymarket fair and safe: identity and onboarding, fraud and financial crime controls, market surveillance, and user protections. You'll partner closely with our Trust & Safety, Surveillance, and Compliance leaders. They define the policy and run the investigations, and your team builds the detection, controls, and tools that make their work possible at scale. WHAT YOU'LL DO

• Own identity verification and onboarding systems (KYC), including vendor integrations, decisioning, and the edge cases that come with them.
• Build fraud and financial crime controls: payment risk checks, AML transaction monitoring, and sanctions screening.
• Build trade and market surveillance that detects manipulation, wash trading, spoofing, and misuse of non-public information, and produce the alerts our surveillance analysts act on.
• Ship user protections such as deposit limits, self-exclusion, and responsible trading controls, and make them reliable across the product.
• Build case management and investigation tooling for the Surveillance, Compliance, and Trust & Safety teams, with the audit trails and records a regulated exchange needs.
• Hire and lead a team of senior engineers, set the technical direction, and balance user friction against risk with good judgment. What we're looking for
• 8+ years in software engineering and 2+ years managing engineers.
• Experience building trust and safety, integrity, fraud, risk, or surveillance systems at a company operating at meaningful scale.
• Comfort working in a regulated environment and translating compliance requirements into concrete system design.
• Strong data-intensive systems skills: event streams, rules engines, detection pipelines, and the tradeoffs between real-time and batch.
• Collaboration with non-engineering partners. You'll work with policy, investigations, and compliance teams every day.
• (Plus) Experience at an exchange, broker, or crypto platform with trade surveillance or AML obligations.
• (Plus) Familiarity with surveillance and compliance vendors (for example trade surveillance platforms, KYC providers, or blockchain analytics).
• (Plus) Applied ML or anomaly detection experience for fraud or abuse.
• (Plus) Experience across both centralized and on-chain products.
