Principal Product Manager - Fraud

As Principal Product Manager of Fraud at Coinflow, you own risk and decisioning across the platform-the systems that decide in real time which transactions are approved and on what terms. Unlike many payment companies, Coinflow carries its own loss risk rather than passing it to merchants. This means your approval-rate and loss-rate decisions land directly on the company's P&L, and you own both sides of that tradeoff. You work across real-time decisioning models, loss economics, merchant-facing risk product, and risk operations tooling, partnering directly with engineering, data science, finance, compliance, and commercial teams.

What you'll do

• Own the approval-rate and loss-rate tradeoff: set the policy, defend the position, and be accountable for both numbers
• Productize risk models in partnership with data science, turning models into decisioning products with clear thresholds, monitoring, and failure behavior
• Build the loss economics view with finance to understand exposure at the portfolio and merchant level, translating that into pricing and policy recommendations
• Ship merchant-facing risk product including decisioning transparency, controls, and reporting that reduce support load and increase trust
• Evaluate and integrate risk infrastructure by assessing signal providers, data sources, and decisioning vendors across coverage, accuracy, cost, and technical fit
• Make calls with incomplete data, deciding when baselines are thin and feedback loops are long, then instrument to learn fast

What you bring

• 7+ years of product management experience, including ownership of a technically complex or regulated surface area
• Experience with products where a wrong decision costs the company money (lending, BNPL, issuing, insurance, risk, or payments products where your employer carried the loss rather than passing it downstream)
• Fluency with loss economics: you can reason about expected loss, unit economics, and how a policy change moves both revenue and exposure
• Experience productizing models: you've shipped against precision/recall tradeoffs and know what breaks when a model meets production traffic
• Track record of shipping end-to-end, from ambiguous problem to production, without a roadmap handed to you
• Strong communication across technical and non-technical stakeholders: you explain risk posture to engineers, finance, and merchants in the same week
• Comfort owning expensive decisions: you'd rather hold the number than advise on it
• Rigor with data and decisiveness without it: you instrument everything and let results change your mind, but you don't stall waiting for certainty that isn't coming
• Operational depth: you learn a workflow well enough to see what the people doing it can't
• Attention to edge cases and failure modes: in this domain the tail is where the money is
• Ability to raise the operating bar: you find the process held together by one person's memory and turn it into something that scales
• Attraction to hard problems: payments risk is high-stakes and unglamorous, and that's the appeal
• Founder or early-employee instincts: you've built from zero, with no team and no one to escalate to

Nice to have

• Fraud, underwriting, or credit risk product experience: you've owned a loss number, not just observed one
• Cross-border payments experience: you've worked risk across markets with different rails, regulators, and fraud patterns
• Product work under heavy regulatory constraint (NACHA, MiCA, BSA/AML, PSD2, or equivalent, where the regulation shaped the design)
• Actuarial, quantitative finance, or data science background, formal or informal

What we offer

• Base salary of $175,000 to $225,000 USD, depending on experience, education, skills, qualifications, and business needs
• Equity grant allowing you to share in the long-term success of the company
• Health and wellness benefits
• 401(k) savings plan
• Flexible time off
