About The Team Do you want to architect the intelligence layer that powers enterprise AI? The AI Core team, part of Workday's AI Platform organization, sits at the frontier of agentic AI — building the foundational systems that enable autonomous agents to reason, act, and deliver deep value across Workday's HR and Finance products.A core belief driving our work: agents are only as good as the information they can access.

Our approach enables our teams to deepen connections, maintain a strong community, and do their best work. We know that flexibility can take shape in many ways, so rather than a number of required days in‑office each week, we simply spend at least half (50%) of our time each quarter in the office or in the field with our customers, prospects, and partners (depending on role). This means you'll have the freedom to create a flexible schedule that caters to your business, team, and personal needs, while being intentional to make the most of time spent together. Those in our remote "home office" roles also have the opportunity to come together in our offices for important moments that matter.Equal Opportunity & Accessibility Pursuant to applicable Fair Chance law, Workday will consider for employment qualified applicants with arrest and conviction records.Workday is an Equal Opportunity Employer including individuals with disabilities and protected veterans.At Workday, we are committed to providing an accessible and inclusive hiring experience where all candidates can fully demonstrate their skills.
