Software Development Engineer, Workday

• Bachelor's degree in Computer Science, Engineering, or equivalent practical experience
• 5+ years of software engineering with a strong focus on backend microservice architectures and distributed systems
• 5+ years of experience in each of the following:
• Programming: Java or Kotlin, with production Spring Boot experience. Go is a plus
• Cloud platforms: AWS (preferred), GCP, or Azure
• Containerization and orchestration: Docker and Kubernetes
• 3+ years operating production services you own — including observability (metrics, logging, tracing), SLO-based alerting, and on-call
• Hands-on experience with AI-augmented development (e.g., Cursor, Claude Code, GitHub Copilot), including the ability to direct, review, and validate agent-generated code

Desirable

• Developer Platform is on a mission to provide the tools and services that make the Workday platform open, extensible, and AI-native giving our customers and a growing ecosystem of external developers the freedom to build whatever their business needs on top of Workday
• Within the Developer Platform, the UI and Tooling server team is the backend engineering team behind that platform. We own both sides of the developer journey: the build-time authoring experience, where developers design, validate, preview, and ship applications, and the runtime UI experience those applications deliver to their users
• Our micro-services serve massive traffic across a global, multi-region Kubernetes fleet under the availability, latency, and compliance bar that enterprise customers demand. Stability, reliability, and resiliency are not a project we run here — they are in our DNA, and they shape how we design, build, and operate every service we own
• We care deeply about developer experience, operational excellence, and using AI to remove friction in the products we ship and in the way we build them. You will own services end to end, work on distributed systems problems that are genuinely hard, and help shape how thousands of developers build on Workday's open platform
• As an Engineer on the UI and Tooling Server team, you will design, build, and operate the backend services at the core of Workday's Developer Platform. You will work primarily across a JVM stack Java and Kotlin, Spring Boot running on AWS and Kubernetes owning features end to end — from API contract, to modern agentic user interface like A2UI, to production health
• Design and deliver backend microservices and developer-facing UI features end to end, taking ownership from technical design through production rollout and ongoing operational health
• Build and evolve well-governed public and internal APIs, applying versioning, backward compatibility, and security standards to surfaces that external developers depend on
• Operate what you build in a cloud-native environment — instrumenting services with metrics, logging, and SLO-based alerting, and participating in on-call to keep a multi-cluster fleet healthy
• Integrate AI and agentic capabilities into the platform, including large language model integrations, real-time streaming interfaces, and Model Context Protocol (MCP) based tooling
• Use AI-augmented development tools as a daily part of your workflow, and help establish team practices for directing, reviewing, and validating agent-generated code
• Partner with product managers, designers, and engineers across teams to break ambiguous requirements into well-scoped, executable work, and clearly articulate technical tradeoffs to both technical and non-technical stakeholders
• Raise the technical bar through code review, design feedback, pairing, and strong test automation, and write clear technical documentation for the features you own
