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.

• Develop tools to improve code reliability and streamline the adoption of our security services.

• Leverage and champion good software design patterns and principles.

• Collaborate closely with support and engineering teams to resolve customer issues, fix bugs, and implement new features.

• Contribute to a collaborative team culture that fosters iteration and innovation.

• Demonstrate excellence when working autonomously, with an understanding of when to seek support from team members.

• Participate in on-call rotation and lead incident response for services to ensure quick service restoration during events.

• Possess the ability to work effectively with both technical and non-technical stakeholders to deliver high-value results.

Our Approach to Flexible Work

With Flex Work, we’re combining the best of both worlds: in-person time and remote. 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.
