As a Mobile UI/Design Engineer, you'll lead the evolution of our mobile interface by focusing on the nuances of interaction and motion. You’ll be responsible for building highly responsive, gesture-rich experiences in React Native that feel native and polished, pushing beyond standard implementations using tools like Reanimated and Skia when needed.
What You’ll Do
- Take ownership of the interaction layer in our React Native app, refining transitions, gestures, and animations to deliver a seamless, 60fps experience
- Collaborate closely with product designers to translate motion concepts into high-fidelity implementations, challenging assumptions where necessary
- Develop reusable animation primitives and interaction patterns that become part of the broader design system
- Diagnose and resolve performance bottlenecks, particularly on lower-end Android devices, by analyzing JS and UI thread behavior
- Contribute to architectural decisions that impact UI responsiveness, including state propagation and rendering efficiency
- Guide fellow engineers in raising the bar for interaction quality and completion standards
What We’re Looking For
- Proven experience building refined mobile interfaces in React Native, with a strong portfolio of shipped work
- Hands-on expertise with Reanimated and gesture handling systems
- Deep understanding of performance profiling across threads and optimization strategies
- Sensitivity to motion design principles—easing, spring dynamics, and frame consistency
- Familiarity with AI-assisted development tools such as Copilot or Cursor as part of your workflow
- Clear, effective communication skills in English, both written and verbal
Nice to Have
- Experience with React Native Skia, custom shaders, or canvas-based rendering for advanced UI
- Knowledge of Swift or Kotlin for bridging or native module integration
- History of creating shared interaction libraries or patterns adopted across teams
- Background in visual or motion design using Figma, After Effects, or similar
- Experience in fintech, trading, or other high-precision domains where UI accuracy builds user trust
- A balanced approach—willing to challenge design decisions while knowing when to ship and iterate
