You might thrive in this role if you: Have demonstrated technical ownership at Staff level or beyond, shaping architecture and delivering substantial initiatives across teams. Have deep expertise in iOS or Android and a track record of shipping and operating production mobile applications. Have professional experience contributing to frontend web or backend development and enjoy working across platforms to move things forward Combine strong engineering fundamentals with product intuition and attention to performance, reliability, and the details of the customer experience.
