Job description

Senior Full Stack Engineer (Mobile & Web)

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

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

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
