About the role

Key responsibilities & impact

Build and maintain the Triple Whale React Native mobile app, with a strong focus on performance, offline resilience, and native-quality UX.
Build and maintain mobile UI components by translating Figma designs into production code using a design token system, collaborating with design and product teams to ensure visual parity with web.
Build data-driven screens with real-time streaming data, charts, and complex list rendering optimized for mobile constraints.
Participate in designing the reactive data layer - state management patterns, server-state caching, and offline-first strategies that work reliably across network conditions.
Participate in mobile infrastructure work: navigation architecture, gesture-driven UI, native module integration, and authentication flows.
Contribute to the technical health of the mobile codebase by enforcing architecture standards, optimizing rendering performance, managing bundle size, and making informed build and tooling decisions.
Leverage AI tooling to assist with development workflows - code generation, refactoring, design-to-code alignment - while applying strong engineering judgment to review and productionize results.
