Soft skills

Strong drive and winning attitude.

Nice-to-have

About this role

We are looking for a Founding Mobile Engineer with 6+ years of experience to architect and build a high-performance crypto trading app from the ground up. You'll be the first and only front-end engineer, owning everything the user touches - from cold start to trade confirmation - at a self-funded, fast-moving team that scaled their last product to $5.4M revenue in year one with just two people.

What will you be doing?

  • Architect the entire React Native mobile app from zero, making all foundational technical decisions
  • Build a best-in-class trading experience (spot + perps) optimized for speed and low latency across all interactions
  • Ship the app from 0 to App Store on a rapid timeline, working closely with the founder and a dedicated UI/UX designer
  • Ensure the app scales to handle 25 50K+ daily active users and $100M+ daily volume with no performance degradation
  • Own production reliability end-to-end - fix critical bugs the hour they land and automate release pipelines

Tech stack

React Native, TypeScript, Expo, Reanimated, Skia, Swift, Kotlin, Privy, viem, Solana, Hyperliquid SDK, PostHog, Sentry.
