About the role
Polymarket is the world's largest prediction market, and trust in every account, deposit and trade is core to the product. As Head of Fraud, you will own Polymarket's fraud risk end to end: defining the strategy, building preventative and detective controls, and making sure every finding is resolved. Found on 1752vc Careers, the job board for startup and VC roles.
What they're looking for
- Influence is the most critical skill for this role, and we'll assess it at every interview stage
- Control design that works. A track record of building preventative and detective controls from scratch and proving they cut losses without hurting good customers
- Breadth across fraud types. Hands-on experience with both first-party and third-party fraud, including account takeover, identity fraud and payment fraud
- AI native. You use AI and automation as your default way of working: for detection models, investigation tooling, case triage and your own day-to-day productivity. You know where models beat rules and where they don't
- Commercial judgement. You understand that the goal is the right balance of loss, friction and growth, not zero fraud. You can put a number on the trade-offs
- Regulatory lens. You know what regulators expect from a fraud program (governance, documentation, testing, escalation) and can defend our approach in an exam
More about this role
Polymarket is the world's largest prediction market, and trust in every account, deposit and trade is core to the product. As Head of Fraud, you will own Polymarket's fraud risk end to end: defining the strategy, building preventative and detective controls, and making sure every finding is resolved.
Your scope covers first-party fraud (customers abusing the platform themselves) and third-party fraud (bad actors targeting our users and systems, including account takeover). You will hold the bar for what good looks like both commercially and in the eyes of our regulators, and you will move fast.
You will partner with and influence Product owners and engineers you don't manage build and ship most fraud controls, so influencing them is critical to success in this role. You'll also work closely with Compliance, Legal, Data, Payments, Customer Support and Security.
Own the fraud risk framework and appetite, and set the roadmap to deliver it.
Maintain a living fraud risk assessment and typology library across onboarding, funding, trading and withdrawals.
Report fraud exposure, losses, control performance and emerging threats to senior leadership and governance forums.
