We're hiring a Principal Product Manager to own risk and decisioning across the Coinflow platform — the systems that decide, in real time, which transactions we approve and on what terms.

This is a role where product decisions carry direct P&L consequences. We don't pass risk through to our merchants; approval-rate and loss-rate outcomes land on our own books. That changes the job. Every threshold, model, and policy you ship is a bet with a cost, and you'll own both sides of it.

The surface area spans:

• Real-time decisioning — the models, rules, and signals that evaluate transactions across 170+ countries and a multi-billion-dollar volume run rate

• Loss economics — understanding where losses come from, what they cost, and how pricing and policy should respond

• Merchant-facing risk product — giving merchants visibility into decisions, and control where they should have it

• Risk operations tooling — the internal surfaces where analysts, underwriters, and ops teams do their work

You’ll work directly with engineering, data science, finance, compliance, and our commercial team. This is a high-ownership, high-ambiguity role: limited structure, problems you'll identify before they're handed to you, and execution you'll drive end to end.

• Own the approval-rate and loss-rate tradeoff — set the policy, defend the position, and be accountable for both numbers

• Productize risk models — work with data science to turn models into decisioning products with clear thresholds, monitoring, and failure behavior

• Build the loss economics view — partner with finance to understand exposure at the portfolio and merchant level, and translate that into pricing and policy recommendations

• Ship merchant-facing risk product — decisioning transparency, controls, and reporting that reduce support load and increase trust

• Evaluate and integrate risk infrastructure — assess signal providers, data sources, and decisioning vendors across coverage, accuracy, cost, and technical fit

• Make calls with incomplete data — much of this space has thin baselines and long feedback loops; you'll need to decide anyway, and instrument so you learn fast

• 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’ll be explaining risk posture to engineers, finance, and merchants in the same week

• Comfortable owning expensive decisions — you’d rather hold the number than advise on it

• Rigorous with data, decisive without it — you instrument everything and let results change your…
