About the Team The Developer Platform team is building the foundation for Workday's open developer ecosystem. We design and deliver the platform capabilities, APIs, SDKs, and developer-facing services that enable external developers and partners to build on Workday products—including Peakon, HiredScore, VNDLY, and more. Our mission is to make the platform reliable, extensible, and straightforward for developers to adopt and extend. We work closely with principal engineers, product managers, and cross-functional teams to turn platform growth goals into well-scoped, high-quality engineering work. We care deeply about technical craft, give direct and constructive feedback, and celebrate shipping capabilities that developers actually want to use. If you are energized by hands-on platform implementation, contributing to architecture decisions, and helping other engineers grow, you will find a collaborative team that values thoughtful execution and makes the work enjoyable along the way. About the Role As a Senior Development Engineer on the Developer Platform team, you will design and build core platform capabilities that advance Workday toward a more extensible, developer-friendly ecosystem. You will deliver high-impact technical work, contribute to architecture and API/SDK design, and collaborate across product and engineering teams to ship reliable, scalable services consumed by internal and external developers.

Collaborate closely with principal engineers, product managers, and cross-functional teams to translate platform growth goals into well-scoped, executable engineering work. Uphold API governance and engineering best practices within your team, including versioning, backward compatibility, and security standards for public-facing surfaces. Mentor junior and mid-level engineers through code review, design feedback, and pairing, and help raise the technical bar on the team. Participate in architectural discussions and contribute to build-vs-integrate decisions for platform components, with grounding in real-world tradeoffs of scale and maintainability. Support developer-facing documentation, onboarding flows, and tooling improvements that make the platform easier to adopt and extend.

Strong API design fundamentals, including REST, GraphQL, OAuth 2.0/OIDC, and versioning best practices, with the ability to apply these to build reliable, well-documented public APIs. Demonstrated ability to lead technical work end-to-end within a team—from design through delivery—with minimal oversight and sound judgment on scope, tradeoffs, and quality. Experience building software consumed by external developers or partners in an enterprise SaaS environment, with an understanding of the reliability and compatibility expectations that public platform surfaces require.
