Software Development Engineer - AI Tools

About the Team

We build AI-powered tools that improve the developer experience, including a code generation platform, AI-assisted code review, and enterprise-wide developer tooling. We own the MCP registry and gateway and develop responsible AI guardrails.

The Workday AI Tools team seeks a software engineer to build infrastructure behind enterprise AI, working with MCP server ecosystem, LLM gateway, and developer-facing tooling. This high-impact, high-ownership role on a small team involves writing production code and supporting engineers who use these tools.

• Build and maintain MCP servers, AI integrations, and developer tools that improve the daily workflow for Workday's engineering org.
• Write scripts and automation that streamline AI tool onboarding, configuration, and fleet management.
• Instrument services with logging and monitoring to keep our platform observable and reliable.
• Work with Security and compliance partners to implement policy requirements in our tooling.
• Participate in code review and help maintain a high standard for the team's codebase.
• Stay current on the AI tooling landscape and contribute ideas for what the team should build or adopt next.

• 3+ years of software engineering experience.
• Production experience building backend services or developer tooling in Python and/or Type Script.
• 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 policy/compliance boundaries.
• Genuine excitement about the cutting edge of AI and current tools, models, frameworks.

• 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 Dev Ops 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; happy to answer questions, support adoption.
• Strong written communication skills; able to document your work clearly for other developers.
