Our engineering department, the Bureau of TechnologyRepresenting a third of our overall team, the Bureau of Technology is structured around some concepts introduced by the foundational “ Spotify model ”: Squads, Tribes, and Chapters.Spread across 5 tribes, the ~20 Product squads are the cross-functional, autonomous teams building and operating services to deliver value to customers and suppliers. They are grouped in tribes addressing a common theme. These Product squads are supported by the ~10 Platform squads which address the cross-cutting challenges, as well as the CyberSecurity team.As a Senior Backend Engineer, you will work closely with all members of your squad, and the Staff engineer of your tribe. Bi-monthly rituals with your tribe and the Backend Chapter will allow you to share what works for your squad, learn what works for others, and make sure your technical direction is aligned with the overall vision.
