Mobile Design Engineer

Most companies treat design and engineering as two practices that translate to each other. We're hiring someone who treats them as one craft. The translation step is where most products lose what makes them feel good. You'll own the feel of the Kraken app: the half-second a trade confirms, the way a chart loads, how a sheet rises from the bottom of the screen and lands where it physically should. On a product where people move their savings, moments like that build trust. This is a mobile-first role on a React Native codebase. We work in Reanimated and Skia, bridge to native when we need to, and sweat the split between the JS thread and the UI thread.

Responsibilities

Own the motion and interaction layer of the Kraken app (easing, springs, gestures, transitions, haptics, sound); Evolve the mobile design system (gesture handlers, transition primitives, animated containers, motion tokens); Partner closely with product designers to elevate motion and interaction design; Profile and optimise rendering performance, especially on lower-end Android devices; Contribute to architectural decisions affecting UI responsiveness (state management, render cycles, data flow into view layer); Raise the bar for quality across the mobile org by review, example, and patterns

Requirements

A portfolio (demo reel, personal site, GitHub of interaction sketches, screen captures of shipped work); Deep React Native fluency (Reanimated, gesture handlers, profiled JS thread vs UI thread work); Taste in motion (opinions about easing curves, noticing over-damped springs, articulating why a transition feels wrong); Product judgment (taking a half-formed brief, finding the actual problem, shaping the spec); AI tools as part of how you work (Cursor, Copilot, Claude, etc.); Written and verbal English

Nice to have

React Native Skia, shader work, or custom canvas-based rendering; Real native experience with Swift or Kotlin (writing bridge modules); A motion library, design-system contribution, or interaction primitive set used by other engineers; Visual or motion design background (Figma, After Effects, or paper); High-stakes product experience in fintech, trading, health, or UI-precision-critical products
