Senior Software Development Engineer - Developer Platform

About the Team

The Developer Platform team builds the foundation for Workday’s open developer ecosystem. We design and deliver platform capabilities, APIs, SDKs, and developer‑facing services that enable external developers and partners to build on Workday products. Our mission is to make the platform reliable, extensible, and easy for developers to adopt.

As a Senior Development Engineer, 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.

• Lead design and implementation of key platform components—including APIs, SDKs, and agentic service integrations—with a strong emphasis on scalability, reliability, and developer experience.
• 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, 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, grounded 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.
