About the Team
At Workday, the Authentication Security team is the cornerstone of our user trust and safety. We build and maintain the critical services that act as the front door to our entire ecosystem. Our mission is to provide secure, scalable, and seamless access for millions of users, protecting their data while enabling a frictionless experience. We are a team of passionate engineers dedicated to solving complex challenges in the authentication and identity space!
About the Role
Join our Authentication Security team as an experienced Software Developer to design and build highly resilient authentication systems for our platform.
