Mobile UI/Design Engineer

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).
