About the role

Responsibilities

  • Own the craft layer of React Native mobile experience — fluid, gesture-driven interactions and transitions that feel native.
  • Push React Native beyond its defaults — Reanimated, Skia, native module bridges.
  • Partner closely with product designers, challenging and elevating motion and interaction design.
  • Establish animation primitives and interaction patterns within the design system.
  • Profile and optimise rendering performance, especially on lower-end Android devices.
  • Contribute to architectural decisions affecting UI responsiveness: state management, render cycles, data flow.
  • Mentor engineers on interaction quality.

Requirements

  • Deep experience building polished mobile interfaces in React Native (Reanimated, gesture handlers, JS/UI thread performance profiling).
  • Trained eye for interaction design (easing curves, spring physics, 60fps constraint).
  • Portfolio or demo reel of shipped work required.
  • Experience with modern AI development tooling (Cursor, Copilot).
  • Strong written and verbal communication skills in English.

Nice to Haves

  • React Native Skia, custom shader work, canvas-based rendering.
  • Native platform knowledge (Swift/Kotlin) for bridging and modules.
  • Built interaction patterns adopted by other engineers.
  • Background in visual/motion design (Figma, After Effects).
  • Experience in high-stakes domains (fintech, health, trading).
