• Familiarity with labeling strategies, model evaluation, and feedback data loops

Desirable

• We’re looking for a Senior Product Manager to own and scale our newly-launched decisioning products: Instant Refunds and Selective Appeasements. These products sit at the core of Signifyd’s expansion beyond fraud — applying machine learning to solve costly, complex problems in returns
• This is a deeply 0-to-1 role. You’ll work directly with our first customers, iterate quickly, shape product-market fit, and collaborate tightly with data scientists, GTM teams, and engineers. The right candidate is comfortable owning ambiguity, moving fast, and staying close to customers
• Own the end-to-end lifecycle of Instant Refunds and Selective Appeasements, from product vision to execution and growth
• Partner with Data Science to shape and iterate on ML models that power decisioning for returns and appeasements
• Define decision outcomes and feedback loops — work with internal teams and merchants to generate quality labels and measurable results
• Work closely with early design partners to refine user experience and ensure product impact
• Collaborate with Customer Success, Sales, and Product Marketing to support deployments, craft narratives, and drive adoption
• Gather qualitative and quantitative feedback from merchants to continuously refine roadmap priorities
• Maintain a strong pulse on the evolving e-commerce returns landscape and merchant pain points
• Operate with urgency and autonomy, making decisions that accelerate value delivery
• Expected 30% travel
