About the Team
You’ll join a Product Engineering team focused on building agent‑ready APIs that power Workday’s next generation of intelligent experiences. We partner closely with internal teams to design and deliver APIs that are secure, observable, and easy to integrate with.
We value innovation, teamwork, ownership, and learning from mistakes as we continuously improve the way we design, deliver, and operate APIs across Workday.
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.
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 or similar languages.
2+ years of experience with web service/API technologies such as REST, SOAP, JSON, XML Schema, WSDL, GraphQL, etc.
Other Qualifications
Bachelor’s degree in Computer Science, Engineering, or a related field, or equivalent practical experience.
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.

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.
