Job description

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


• Strong knowledge of JavaScript/TypeScript and modern ES6+ features


• Experience with CI/CD tools and mobile testing frameworks


• Experience with Firebase, GraphQL, or REST APIs


• Strong leadership skills with the ability to mentor and guide developers


• Excellent communication and collaboration skills


• Experience working in Agile/Scrum environments

Good to Have

• Previously worked in the fintech/proptech industry


• Deep experience in both Angular and React.js for web


• Prior native iOS or Android development experience (Swift/Objective-C or Kotlin/Java) predating React Native


• Previous experience in a startup or fast‑paced product environment


• Experience with SSR, SPA implementation on the web side


• Knowledge of additional programming languages or frameworks
