About The Role

We are seeking a highly experienced Senior Software Engineer with 6+ years of proven expertise architecting and shipping production React Native applications, and hands-on command of the Expo ecosystem including EAS. This role is primarily mobile: you will own our iOS and Android apps end to end - architecture, performance, release management, and app store operations - while also contributing to our web frontend (Angular and/or React) as needed. You will be a key member of the engineering team, and mentoring engineers.

Key Responsibilities

Mobile

Architect and build scalable, performant mobile applications using React Native and Expo, including apps with custom native modules or native code where required
Own the full mobile release lifecycle: EAS builds, OTA updates, app store submission and compliance (App Store / Google Play), versioning strategy, and rollout/rollback processes
Debug and resolve complex native-layer issues — performance, memory, platform-specific bugs, native module bridging (Android/Java, iOS/Swift or Objective-C)
Design mobile app architecture, navigation, and state management (Redux, Zustand, Recoil, or similar) for scale and maintainability
Set and enforce mobile engineering standards: testing frameworks, CI/CD pipelines for mobile builds, code review practices
Integrate analytics/observability tooling (Amplitude, Sentry, Google Analytics) into mobile apps to monitor app health and user behavior
Mentor engineers on mobile architecture, native debugging, and release best practices

Web

Contribute to and maintain our web frontend using Angular and/or React.js, working from design specifications with reusable, well-architected components
Support frontend performance efforts (Core Web Vitals, Lighthouse) as needed
Use Storybook to collaborate with design and product functions

Cross-Platform / Shared

Work closely with Product and Design teams to deliver the best end-user experience across mobile and web
Collaborate with the Backend team on API design; evaluate and integrate third-party APIs and services
Ensure high-quality unit/integration test coverage using appropriate mobile and web testing frameworks
Participate in code reviews across the mobile and web codebases
Contribute to agile processes and the technical roadmap for mobile and frontend services
Stay current with emerging mobile and frontend technologies and recommend tooling/practice improvements

Must Have

6+ years of mobile engineering experience, with 4+ years hands-on production React Native and Expo (including EAS for builds, OTA updates, and deployment)
Demonstrated ownership of mobile app architecture, native module integration/bridging, and app store release management
Strong understanding of mobile performance, navigation, and state management (Redux, Zustand, Recoil, or similar)
Working proficiency in at least one of Angular or React.js for web contributions
