If you appreciate the challenge of transforming a proven, production-hardened architecture to: - Integrate and scale intelligent agents across the platform (e.g., for recruiting, learning, financial close, and contract intelligence). Improve resilience, availability, and efficiency by orders of magnitude in support of our Enterprise customers. - Empower an organization of 1,000s of application developers to build agent-enabled experiences. - Unlock new business growth opportunities by leveraging newly acquired capabilities (e.g., from Sana, Paradox, and Evisort), then this role could be a great fit. About the Role As a member of the Core Services Architecture team, the Distinguished Architect will work with innovative and experienced engineers to design the projects that will help define the future of the core Workday architecture—transforming it from a system of record into an intelligent system of action . You will take on the challenge of architecting the underlying infrastructure to support massive scale, zero downtime, and the operationalization of a multi-agent environment, all while optimizing operational costs.
