- Experience building high-quality mobile UI using Jetpack Compose and/or the traditional Android View system
- Strong product sense and care for mobile user experience, polish, responsiveness, and reliability
- Ability to make independent architecture decisions and clearly explain technical tradeoffs
- Strong ownership mindset and ability to drive work end-to-end in a fast-paced environment
- Comfortable collaborating closely with Product, Design, Backend, Mobile, and Growth teams
