## Description

We’re Workday, a Fortune 500 company and a leading AI platform for managing people, money, and agents. We're looking for a senior engineer to join our AI Tools team, which focuses on building AI-powered tools that eliminate friction from the developer experience.

**About the Role**

The Workday AI Tools team is looking for a senior engineer who thrives at the intersection of AI, platform engineering, and developer experience. You'll design and build systems that thousands of Workday engineers rely on every day - from LLM gateways and MCP server infrastructure to AI-native agents and compliance tooling. You'll help define how we integrate emerging AI capabilities into our platform, and you'll be a technical anchor on a team that moves fast and takes quality seriously.

**Responsibilities**

- Design and build the AI platform layer: LLM gateways, MCP registries, abstraction APIs, and shared infrastructure that teams across Workday build on

- Architect and implement AI agents and automation that improve the developer workflow - code review, documentation, testing, and beyond

- Drive the evaluation and integration of AI model providers, keeping a strong eye on cost, safety, and performance tradeoffs

- Serve as a scout for emerging AI capabilities - track new models, tools, and frameworks, and make recommendations to engineering leadership on when to adopt, evaluate, or pass

- Lead technical design on complex, cross-cutting projects in partnership with Security, DevEx, and infrastructure teams

- Build observability and governance tooling that gives the organization visibility into how AI tools are being used

- Operationalize AI policy and compliance requirements into our platform

**Requirements**

- 5+ years of software engineering experience

- 3+ years building and operating backend services or platform infrastructure in production

- Strong proficiency in Python and/or TypeScript

- Hands-on experience building or integrating with LLM APIs (OpenAI, Anthropic, etc.) and familiarity with prompt engineering, evaluation pipelines, and model selection tradeoffs

- Robust understanding of AI security principles and responsible AI practices

- Genuine excitement about being on the leading edge of AI

**Benefits**

- Annualized base salary ranges: $190,100 USD - $285,100 USD (primary location)

- Comprehensive benefits package

- Flexible work arrangements: spend at least half (50%) of your time each quarter in the office or in the field
