About The Position

The Workday AI Tools team is looking for a software engineer who's excited to build the infrastructure behind enterprise AI. You'll work across our MCP server ecosystem, LLM gateway, and developer-facing tooling - writing real production code that Workday engineers use every day. This is a high-impact, high-ownership role on a small team that moves quickly, so you'll have room to grow fast. You'll also work directly with the engineers using these tools - answering questions in Slack, supporting onboarding, and feeding their feedback back into the platform.

Requirements

3+ years of software engineering experience
Production experience building backend services or developer tooling in Python and/or TypeScript
Familiarity with LLM APIs and basic prompt engineering concepts
Working understanding of AI security and responsible AI principles - including awareness of prompt injection, data handling risks, and how to build AI integrations that respect policy and compliance boundaries
Genuine excitement about the cutting edge of AI - you stay current on new tools, models, and frameworks, and you're eager to bring what you're learning into your day-to-day work

Nice To Haves

Understanding of AI agent architectures, including the ReAct pattern and how agents reason, plan, and use tools iteratively; hands-on experience building or experimenting with agents is a plus
Experience building MCP servers, skills, or tool-use integrations; comfort reading and contributing to the MCP ecosystem
Experience building or consuming REST APIs
Working knowledge of Docker and container-based deployments; experience with Kubernetes is a plus, and exposure to workflow orchestration or infrastructure-as-code tooling is welcome
Familiarity with DevOps practices and CI/CD systems
Understanding of authentication and authorization fundamentals (OAuth, SSO, API keys)
Comfort working in a cloud environment (AWS, GCP, or Azure)
Experience adding observability to services - logging, metrics, alerting
Comfort partnering directly with the engineers who use your tools - you're happy to answer questions, support adoption, and treat user feedback as input, not interruption
Strong written communication skills; able to document your work clearly for other developers
