What you'll do
Build and improve the cart, checkout, and wallet flows in our React Native: apps, from problem definition through to production and measurement
Run experiments on high-traffic, revenue-critical surfaces, and use the results to decide what ships next

Design and develop solutions that can continue to scale
Support other team members through workshops, pair programming, and code reviews
Solid hands-on experience working with AI coding agents (e.g., Claude Code,: Cursor, Copilot) beyond casual experimentation. You use AI agents as thought partners to onboard on unfamiliar codebases and navigate new areas of the code with confidence. You have a practical sense of how the context you provide to AI tools - specifications, constraints, examples - shapes output quality, and a developing awareness of how agentic outputs can fail, with growing habits around verifying, testing, and setting boundaries on AI-generated work.
What they're looking for
- At least 2-3 years of hands-on work with React Native
- A minimum of 5 years of experience working with HTML, CSS, and JavaScript
- Proficiency in building component-based architectures using React.js and Node.js
- Deep understanding of integrating frontend and backend services seamlessly
