## Description

We're looking for a Senior Mobile Engineer (React Native) to work on a long-lived, production-scale React Native codebase where architecture, performance, and developer experience are core priorities. You'll build mobile experiences that support discovery, messaging, lead flow, and transactions for a large user base, and you'll help drive technical direction across the mobile platform., This role is for engineers who like going deep-profiling performance, eliminating re-render bottlenecks, designing scalable patterns, handling offline/flaky-network scenarios, and integrating with native iOS/Android when needed. You'll collaborate with product, design, backend, and architecture partners while owning features end-to-end and mentoring other engineers.
