Become a Krakenite and build the future of crypto!

The Consumer Mobile team builds the Kraken app — the interface millions of people use to interact with their money. We work in React Native and care deeply about how the product feels, not just whether it functions. A trade confirmation should feel instantaneous. A portfolio should feel alive. Navigation should feel effortless. These details directly impact trust, and trust is everything in crypto.

• Most mobile engineers can build screens. This role is for someone who makes interfaces feel right — the weight of a gesture, the timing of a transition, the moment a loading state becomes invisible. You obsess over these details not because a designer asked for them, but because you can't ship something that feels wrong.

  • Own the craft layer of our React Native mobile experience — fluid, gesture-driven interactions and transitions that feel native, not web-in-a-wrapper

  • Push React Native beyond its defaults — Reanimated, Skia, native module bridges when the abstraction isn't enough

  • Partner closely with product designers, challenging and elevating motion and interaction design from concept through implementation

  • Establish animation primitives and interaction patterns within our design system that other engineers build on — your work becomes the quality floor for the team

  • Profile and optimise rendering performance, especially on lower-end Android devices where frame drops are unforgivable

  • Contribute to architectural decisions that affect UI responsiveness: state management, render cycles, and data flow into the view layer

  • Mentor engineers on interaction quality and raise the standard for what "done" looks like across the mobile org

• Deep, demonstrable experience building polished mobile interfaces in React Native — you know Reanimated well, you've fought with gesture handlers, and you've profiled JS thread vs UI thread performance and won

• A trained eye for interaction design — you notice when an easing curve is wrong, you have opinions about spring physics, and you understand that 60fps isn't a target, it's a constraint

• A portfolio or demo reel of shipped work is a hard requirement — a personal site, video walkthrough, GitHub interaction demos, or screen captures of work you're proud of. If we can't see your craft, we can't evaluate it

• Experience with modern AI development tooling (Cursor, Copilot, or similar) as a natural part of how you build — not as a novelty, but as a multiplier

• Strong written and verbal communication skills in English

• Experience with React Native Skia, custom shader work, or canvas-based rendering for non-standard UI

• Some native platform knowledge (Swift/Kotlin) for when you need to drop below the RN abstraction — bridging, native modules, platform-specific behaviour

• You've built interaction patterns that other engineers adopted — shared animation libraries, gesture primitives, motion design systems

• Background in or affinity for visual/motion design — maybe you prototype in Figma or After Effects before you write code, maybe you sketch interaction flows on paper. Either way, you think visually

• Experience in high-stakes product domains (fintech, health, trading) where UI precision affects user trust

• Strong opinions, loosely held — you push back on designs that won't translate well to mobile and advocate for the user's experience, but you also know when to ship and iterate
