Senior Engineering Manager, Trust & Safety, Surveillance & Compliance

As Senior Engineering Manager for Trust & Safety, Surveillance & Compliance at Polymarket, you lead the systems that keep the world's largest prediction market fair and safe. Polymarket operates a CFTC-regulated exchange and clearinghouse, and you partner closely with Trust & Safety, Surveillance, and Compliance leaders to build the detection, controls, and tools that make their policy and investigation work possible at scale.

What you'll do

• Own identity verification and onboarding systems (KYC), including vendor integrations, decisioning, and edge cases.
• 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 your 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 requires.
• Hire and lead a team of senior engineers, set the technical direction, and balance user friction against risk with good judgment.

What you bring

• 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 the ability to translate 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 processing.
• Proven collaboration with non-engineering partners such as policy, investigations, and compliance teams.

Nice to have

• Experience at an exchange, broker, or crypto platform with trade surveillance or AML obligations.
• Familiarity with surveillance and compliance vendors such as trade surveillance platforms, KYC providers, or blockchain analytics.
• Applied machine learning or anomaly detection experience for fraud or abuse.
• Experience across both centralized and on-chain products.

What we offer

• Base salary of $250,000 to $400,000 annually, plus equity and benefits.
• Unlimited PTO.
• Health, vision, and dental coverage.
• 401(k) match.
