Workday Workday · Enterprise · Atlanta, GA

Workday is seeking a Senior/Principal Machine Learning Engineer to design and build core ML systems for AI agents. This role involves owning the full lifecycle of LLM-powered agents, including RAG pipelines, orchestration, deployment, monitoring, and continuous improvement, with a focus on production-grade, scalable, and enterprise-ready solutions embedded within Workday's platform.

What you'd actually do

  1. design and build the core ML systems behind Workday’s next generation of AI agents
  2. implement and evolve frameworks for LLM-powered agents, including RAG pipelines, workflow orchestration, evaluation, and feedback loops, ensuring solutions are scalable, observable, and enterprise-ready
  3. stay hands-on with emerging techniques in agentic architectures while applying strong engineering judgment to turn them into systems that are reliable, explainable, and built to operate at global scale
  4. partnering closely with software engineers, product managers, and data scientists to integrate agents deeply into the Workday stack
  5. take products through applied research, design, implementation, production, and production-based evaluation
