As a Fortune 500 company and a proven enterprise cloud platform, Workday brings modern technology, responsible AI, and secure infrastructure to some of the most complex environments in the world. The work isn't theoretical. It's operational. It's high-impact. And it demands rigor, integrity, and long-term thinking.
The Developer Portal team builds the UI for the Workday Build Platform, empowering our developer community to extend the value of Workday. Our work directly supports the growth of the platform - and the growth of Workday itself - as many features that require a UI come through our team. We are evolving into a platform enablement team, transitioning to support multiple micro-frontends, which means the technical challenges ahead are both meaningful and exciting.

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.
