Senior Full Stack Developer (React Native + Web)

As a Senior Full stack Developer, you'll play a key role in building and improving our SaaS platform across all surfaces - mobile, web, and backend. You'll lead the technical direction of our React Native mobile app as we scale it into a fully independent experience for mobile-first markets, while contributing just as actively to our web platform - from creating intuitive user interfaces in React to developing scalable APIs and backend services with Node.js.

You'll collaborate closely with product managers, designers, and fellow engineers to turn ideas into impactful features our customers truly love.
