Senior Front End Engineer

Role Overview

• Design and build mobile features: Architect and implement complex features and interaction flows in our React Native app that are performant, accessible, and deliver exceptional user experiences.
• Own technical delivery: Lead the technical design and implementation of complex features end-to-end — from product requirements through deployment and monitoring.
• Drive app performance: Diagnose and resolve performance bottlenecks, optimize rendering, reduce bundle size, and improve the overall responsiveness of the mobile app.
• Define technical direction: Propose and drive architectural decisions for your team’s mobile features, evaluating tradeoffs and communicating recommendations clearly.
• Mentor and elevate: Provide hands-on mentorship to Software Engineers I, II, and III on your team and in the organization through code reviews, pairing, and technical guidance.
• Improve engineering practices: Define, advocate for, and improve best practices around component architecture, testing, accessibility, and mobile deployment for your team.
• Collaborate cross-functionally: Work closely with Product Managers, Designers, QA, and other engineering teams to translate product goals into well-scoped technical solutions.
• Participate in on-call rotation: Share responsibility for production incidents, contributing to root cause analysis and long-term reliability improvements.

Requirements

• 5–8 years of professional software engineering experience, with significant time building production React Native applications
• Proven track record of owning and delivering complex, multi-component mobile features in a team environment
• Experience with the full mobile development lifecycle — from development through app store submission and post-release monitoring
• Experience building mobile applications backed by large-scale, high-throughput distributed systems serving millions of users
• Expert-level TypeScript proficiency — you write clean, type-safe, well-tested production code
• Deep React Native expertise — performance optimization, native module integration, complex animations, and platform-specific considerations
• Strong experience with Expo and its ecosystem
• Proficiency with monorepo tooling (Yarn workspaces or similar)
• Solid understanding of mobile testing strategies — Jest for unit/component testing, experience with Maestro for E2E testing
• Experience with CI/CD for mobile and Expo/EAS workflows — build pipelines, OTA updates, app store deployment
• Understanding of observability in mobile — crash reporting, performance monitoring, analytics integration
• Comfortable working autonomously with minimal direction on ambiguous problems
• Effective communicator who can articulate technical decisions to both engineers and non-technical stakeholders
• Experience working in a fully remote engineering organization
• Able to context-switch between deep technical work and collaborative planning
