About the role

  • Senior/Principal Machine Learning Engineer designing ML systems for Workday’s AI agents. Overseeing full lifecycle from problem framing to deployment while collaborating with cross-functional teams.

Responsibilities

  • Design and build the core ML systems behind Workday’s next generation of AI agents.
  • Own how models, agent logic, and orchestration layers come together in production—across the full lifecycle from problem framing and data strategy to deployment, monitoring, and continuous improvement.
  • 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.
  • Partner closely with software engineers, product managers, and data scientists to integrate agents deeply into the Workday stack.
  • 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.

Requirements

  • 10+ years experience as a member of a data science, machine learning engineering, or other relevant software development team building applied machine learning products at scale
  • 4+ years of professional experience in machine learning and deep learning frameworks & toolkits such as Pytorch, TensorFlow
  • 6+ years of professional experience in building services to host machine learning models in production at scale
  • 3+ years of demonstrated experience working with large language models (LLMs), text generation models, and/or graph neural network models for real-world use cases
  • 6+ years of proven experience with cloud computing platforms (e.g. AWS, GCP, etc.)
  • Proven track record of successfully leading, mentoring, and/or managing ML Engineering teams, taking ownership of development lifecycle and sprint planning; fostering a culture of collaboration, transparency, innovation, and continuous improvement
  • Bachelor’s (Master’s or PhD preferred) degree in engineering, computer science, physics, math or equivalent
  • Stay up to date with advancements in AI, LLMs, RAG, autonomous agents and orchestration frameworks to drive innovation
  • Deep understanding of statistical analysis, unsupervised and supervised machine learning algorithms, and natural language processing for information retrieval and/or recommendation system use cases
  • Professional experience in independently solving ambiguous, open-ended problems and technically leading teams
  • Excellent interpersonal and communication skills, with the ability to build strong relationships across teams and stakeholders.

Benefits
