Help build the next generation of Affirm's platform and define our presence around the world. What you’ll do You will be responsible for owning and delivering quarterly goals for your team, leading engineers on your team through ambiguity to solve open-ended problems, and ensuring that everyone is supported throughout delivery. You will support your peers and stakeholders in the product development lifecycle by collaborating with product management, design & analytics by participating in ideation, articulating technical constraints, and partnering on decisions that properly consider risks and trade-offs. You will proactively identify project, process, technology or business issues, advocate for them, and lead in solving them.

Become a part of our caring community Humana’s Digital Health Platform (DHP) is the engineering platform behind many of Humana’s consumer digital experiences. DHP Product Engineering builds the shared pieces other Humana teams build on, including a micro-frontend catalog, accessibility tooling, and API foundations, and we build them with AI coding agents at the center of how we work. We are hiring a Senior Product Engineer who wants a say in what gets built as well as the craft of building it, from accessible interfaces to the services behind them. You will own features across the whole stack, and you decide the technical approach for the work you own. You use AI coding tools like Claude Code every day, and you help build the shared skills and tooling behind that workflow. We measure your work by the results it produces for Humana’s members and patients and for the teams who build on our platform. The Senior Product Engineer helps decide what we build, not just how we build it. This is a senior engineering role at its foundation. You design, develop, and deploy scalable web applications end to end, and you meet a high bar for engineering craft. You also own the product: you shape what we build, influence what goes on the roadmap, and are measured by the outcomes your work produces rather than the tickets you close. You explore before you commit, propose the work as often as you receive it, and sharpen requirements rather than simply implement them. You will build accessible user interfaces, implement robust back-end microservices, and integrate the two with GraphQL, all while exercising considerable latitude over technical approach. Strong product instinct here does not lower the engineering bar; it raises the overall one. Required Qualifications Bachelor’s degree in Computer Science or a related field 5 or more
