Many of these experiences are now powered by agents and AI, which depend on a strong API foundation. This role sits in Product Engineering but operates across product pillars. You will work closely with Product Engineering teams as well as partner organizations. You will shape the API foundation, architecture and operating model that makes it easy for Product Engineering to build agent‑ready, high‑quality APIs. About the Role As a Software Development Engineer in Product Engineering, you will help build and maintain the APIs and backend services that sit on the critical path for Workday products and agentic experiences. You will work with technologies such as TypeScript/Python and Workday frameworks to develop scalable, resilient distributed systems and great internal developer experiences. Your work will directly impact how quickly Workday can build, deploy, and iterate on agent‑driven capabilities for customers. What you’ll do • Design, develop, and maintain product APIs and backend services. • Implement robust API behaviors including routing, validation, authentication/authorization, transformation, and error handling. • Contribute to high‑throughput, low‑latency components and integrations, focusing on resiliency, scalability, and fault tolerance. • Apply API contract and governance practices using OpenAPI/Swagger and internal standards. • Build and improve frameworks and tooling used by Product Engineering teams to define, publish, and maintain APIs (REST, SOAP, Graph, etc.). • Use observability (metrics, tracing, logging) to understand behavior in production and drive performance and reliability improvements. • Write clean, well‑documented, and testable code; contribute unit, integration, and contract tests. • Participate in design and code reviews; share knowledge through documentation, talks, and mentoring. • Own small to medium services or API areas end‑to‑end — from design and implementation through rollout, monitoring, and support. • Collaborate with partners in other Workday code service and agent development teams.
