They are seeking a Full-Stack Software Engineer to develop features for their mobile app, fix bugs, and maintain backend services, while working closely with a small team.
Responsibilities
- Build and ship features in our React Native + Expo mobile app (TypeScript): screens, navigation, onboarding flows, in-game UI, and social features
- Fix bugs and triage crashes from Sentry. Reproduce, find the root cause, and ship the fix
- Make small-to-medium backend changes in our Python/FastAPI services backed by PostgreSQL
- Help maintain our internal React/Vite admin panel with contest setup, test tooling, data pipelines, etc
- Turn Figma designs into clean, consistent UI and polish rough edges (spacing, transitions, empty/error states)
- Help with day-to-day release work: running iOS/Android builds, chasing down native build issues, and getting changes deployed
Skills
- 0–2 years, or strong bootcamp/self-taught with a portfolio
- Strong AI dev skills. Use Cursor or Claude Code effectively but still able to talk through and explain your code. Being able to use it as a tool but not over-reliant
- Solid JavaScript/TypeScript fundamentals and some hands-on React Native
- Comfortable reading code you didn't write and tracing a bug across the front end and an API
- Basic Git workflow and the ability to work independently from a written task
- High ownership and scrappy, but not afraid to ask questions
- Cares about the user-facing result, not just 'the ticket is closed.'
- Any Python (FastAPI a bonus) and basic SQL / PostgreSQL
- Familiarity with Firebase Auth, Sentry, or mobile app store submission
- Exposure to real-time systems (WebSockets/SSE), or any sports/gaming/fintech product
Benefits
- Small team, direct access to the founder, fast feedback loops.
- High ownership over deliverables with easy access to support and mentorship
- You'll be supported with clear tasks and code review, with room to grow into owning whole features.
