About the team
The UI Platform team, known as Sail, builds the foundations that support the company's Dashboard and many of the company's other user interfaces. The Sail Services team provides backend-for-frontend services that help product teams build consistent, scalable user experiences.
The team is defining its mission, roadmap, and technical vision as the UI platform takes on a more central role in how the company builds user interfaces. We work with engineers, product managers, and designers across the company to connect the design system,



software development kits, and backend services into a consistent, surprisingly delightful user experience.
