  • Act as a technical reference for your team and share your experience with other Android Engineers across the Tribe.
  • Help improve our architecture, tooling, and performance practices.
  • Mentor your peers through code reviews, pairing, and knowledge sharing.
  Apply a product-first mindset, balancing user value with technical excellence.

• An excellent Computer Science foundation (data structures, algorithms, software design).
• Experience working in large modular codebases shared by multiple teams.
• A data-driven mindset with strong analytical skills.
• The ability to balance technical trade-offs with product impact.
• Strong communication skills and a growth mindset, with an openness to learning and knowledge sharing.
