About the role

Key responsibilities & impact

Design, ship, and maintain features in our React Native + Expo app - in-app screens, navigation, state, and the native web bridge that powers them.
Build and extend native-adjacent capabilities (performance-sensitive UI, native module integrations, OTA-delivered updates) used by millions of shoppers every day.
Prototype new in-app experiences in weekly sprints, validate with live merchants, and iterate to release across thousands of apps.
Own features end-to-end across the stack - from the React Native client into the React/Next.js content layer and the services behind it - without handing off at boundaries.
Optimize app performance, startup time, bundle size, and accessibility, and contribute to the reusable, type-safe component patterns that keep our experiences consistent.

Requirements

What you’ll need

5–7 years of experience in software engineering
3+ years building production React Native apps (TypeScript), with strong React fundamentals
Working knowledge of the Expo framework
Demonstrated ability and appetite to work across the stack - React/Next.js on the web side, and the services your features depend on - not just within the mobile client
Comfort owning a feature end-to-end in a fast-paced, cross-functional environment
Experience with mobile app performance, debugging, and release/OTA workflows.
Bonus if you have experience with native modules (Swift/Kotlin) or bridging native and web layers.
Bonus if you have full-stack or backend experience (Node.js, GraphQL, cloud deployments and hosting).
Bonus if you have Shopify or ecommerce experience.
Bonus if you have experience building or maintaining design systems / component libraries.
Bonus if you have a background in UX, product, or design critique.
Bonus if you have contributions to open-source mobile or component-library tooling.
