We are hiring a Staff / Senior Staff Frontend Engineer to lead the next evolution of our frontend platform, with a primary focus on our React Native mobile apps (iOS & Android) and supporting web (React) surfaces where they add value.

Requirements

8+ years of engineering experience (or equivalent impact)
Deep experience with React and strong experience with React Native in production
Proven experience leading large-scale frontend refactors or platform transformations
Strong frontend system design fundamentals beyond UI implementation
Experience with performance optimization, design systems, and frontend tooling
Familiarity with CI/CD for web and mobile applications
Comfort collaborating across teams, closely with backend experts, product and stakeholders, working end-to-end when needed If you enjoy shaping frontend platforms, improving performance and reliability at scale, and raising the bar across teams — we’d love to talk.
