About the Team
The Product Engineering organization builds the product experiences that Workday customers use every day. Our teams design and deliver features on top of Workday's core platforms and services, and increasingly depend on powerful, well-designed APIs to support agentic experiences and AI-driven scenarios.
This team focuses on evolving the API surface and supporting mission-critical product flows for agentic AI use cases. We are essentially building the "neural pathways" for Workday's next-generation applications — designing and scaling APIs that are optimized not only for human developers, but for AI agents to understand and act on autonomously. We partner closely with internal Workday teams to design APIs and patterns that are consistent, reliable, and easy to consume. We also act as a center of excellence for API governance, setting the standards that help the entire organization build with confidence.
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.
This role is crucial because agentic AI changes how APIs must be built. For an AI agent to successfully process an invoice, update an employee record, or orchestrate a complex workflow within Workday, the underlying APIs must be highly deterministic, self-describing, and resilient. You will be at the center of making that possible.
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.
About You
Basic Qualifications
5+ years of experience in software engineering building scalable backend services or platforms.
3+ years of experience with TypeScript or Python in production environments
2+ years of experience with web service/API technologies (such as REST, SOAP, JSON, XML Schema, WSDL, GraphQL, etc) with an emphasis on contract-first design (OpenAI / Swagger)
2+ years of experience working with distributed systems architecture, handling high-throughput workloads, concurrency management, or advanced caching strategies
Other Qualifications
Demonstrated proficiency with modern AI‑assisted development tools (e.g., Cursor, Claude Code, GitHub Copilot) to accelerate high‑quality software delivery.
Solid algorithmic thinking (e.g., hash maps, trees, graph traversal, caching strategies) applied to routing, query planning, or data transformation.
Familiarity with distributed systems concepts: concurrency/multithreading, horizontal scaling, high availability, and fault tolerance.
Understanding of typical API gateway responsibilities: routing, validation, authentication, throttling/rate limiting, transformation, and security policies.
Experience with API specifications and lifecycle (OpenAPI/Swagger, versioning, documentation).
Good understanding of testing methodologies (unit, integration, contract, performance) and tools such as JUnit, ScalaTest, Postman, Mockito, and coverage tools.
Experience with source control and modern dev tooling (Git/GitHub, Gradle, CI, debugging, profiling).
Exposure to cloud‑based development (e.g., AWS, Kubernetes) is a plus.
Familiarity with MCP or similar integration models is a plus.
Strong communication skills and a collaborative mindset; comfortable working with teams across time zones.
Curiosity about agentic AI and interest in building APIs that power AI‑driven workflows.

Our Approach to Flexible Work
With Flex Work, we’re combining the best of both worlds: in-person time and remote. Our approach enables our teams to deepen connections, maintain a strong community, and do their best work. We know that flexibility can take shape in many ways, so rather than a number of required days in-office each week, we simply spend at least half (50%) of our time each quarter in the office or in the field with our customers, prospects, and partners (depending on role). This means you'll have the freedom to create a flexible schedule that caters to your business, team, and personal needs, while being intentional to make the most of time spent together. Those in our remote "home office" roles also have the opportunity to come together in our offices for important moments that matter.
