Role details

Responsibilities

  • Drive the Android side of the Adaptive Plan mesocycle-driven progressive-overload engine end-to-end alongside the CTO
  • Ship, polish, debug, and repeat with extreme ownership
  • Work end-to-end so your code is used by millions of users
  • Drive the Android side of the Progressive Overload engine end-to-end.
  • Shipping Adaptive Plan at the level our most serious users expect.
  • Own the Android side of the Progressive Overload engine and ship it at the level our most serious users expect.
  • Making our mesocycle engine feel native on Android: clean Compose UIs, fast offline-first sync, instant load progression updates after every set.
  • Fix custom-exercise + bodyweight/duration-based exercise contributions to our progression dashboard. Unblocks home-training users from adopting the Adaptive Plan.
  • Onboarding conversion, activation, and subscription retention.
  • Migrating off the last legacy patterns; deeper Compose adoption; Coroutines/Flow everywhere.
  • Ship faster using Claude Code / Cursor / Copilot.

Requirements

  • Shipped real Android products to Play Store (solo side projects count)
  • Kotlin + Jetpack Compose + Coroutines, or actively learning them
  • AI-coding-assistant fluency is non-negotiable: Claude Code, Cursor, Copilot integrated into daily workflow
  • Offline-first / Room / SQLite mindset (runs in real gym environments where WiFi is bad)
  • Extreme ownership end-to-end
  • Shipped real Android software. At least one app on Google Play, or a substantial Android codebase at a company.
  • Solid Kotlin + modern stack. Jetpack Compose, Coroutines/Flow, Room (or SQLDelight) in production. If your last 3 years were XML + RxJava + AsyncTask and you haven't picked up Compose yet, this isn't the right fit.
  • Genuine AI-coding-assistant fluency. Not "I use ChatGPT to debug sometimes" — we mean Claude Code / Cursor / Copilot integrated into your daily dev loop, with opinions on workflow. We bias hard toward fast learners over stack-stubborn experts; this is the single most important non-Android skill we screen for.
  • Authorization to work in the US without visa sponsorship. Citizen / GC / EAD / TN. We can't sponsor H1-B for this role.
  • Willingness to work full-time in our San Jose office. This is an in-office role, 5 days/week. Not remote, not hybrid.
