The Consumer Mobile Team
We build the Kraken app — the interface millions of people use to interact with their money. Working in React Native, we focus on how the product feels, not just whether it functions. The experience must feel instantaneous, alive, effortless, and trustworthy.
Opportunity
- 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: use Reanimated, Skia, and 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.
Skills You Should HODL
- Deep, demonstrable experience building polished mobile interfaces in React Native — you know Reanimated, you’ve fought with gesture handlers, and you have profiled JS 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 60 fps isn’t a target
