Senior Software Engineer, React Native
Tapcart is the leading mobile app platform for the as fastest-growing Shopify brands. We help marketers and eCommerce teams strengthen their brands and create differentiated customer experiences through a direct mobile channel.
Our platform powers mobile shopping for over 50 million consumers and processes more than $8 billion in revenue annually. Brands like Béis, Grove Collaborative, and Ruggable trust Tapcart to turn mobile traffic into high-retention, high-growth relationships - with mobile apps launched in hours, not months.
THE ROLE
As a Senior Software Engineer on the React Native team, you'll work primarily on our mobile application framework - that millions of shoppers open every day - building the in-app experiences, native capabilities, 3rd party integrations, and ecommerce interfaces that define the Tapcart product. You'll own features end-to-end, from problem statement to production, and help shape the patterns and architecture that keep our apps fast, scalable, and extensible.
This is a full-stack, end-to-end role, suited to a builder who is most at home in mobile but is curious and comfortable reaching across the stack. We expect everyone on the team to take ownership of their work, collaborating directly with merchants from POC to general access release. You may go deep in one area (runtime performance, local data and caching, native modules, etc.), but curiosity and willingness to work across the whole stack is the baseline, not the exception. You are passionate about applying AI tools creatively to your own work and sharing internal tools and knowledge with our internal engineering team.
HOW YOU WILL MAKE AN 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.
WHAT SKILLS 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.
Full-stack or backend experience (Node.js, GraphQL, cloud deployments and hosting).
Shopify or ecommerce experience.
Experience building or maintaining design systems / component libraries.
Background in UX, product, or design critique.
Contributions to open-source mobile or component-library tooling.
