Senior Full Stack Developer

nXscale provides flexible outsourcing solutions for startups and scaleups. We partner with global companies to help them build teams and scale operations.

Our client is seeking a Senior Full-Stack Engineer to take ownership of end-to-end delivery of product features across a React/React Native frontend and Node.js APIs. You’ll work independently within a venture-backed AI startup, contributing to a Next.js web app, React Native mobile app, and building reliable integrations with third-party APIs used daily by clients.

In this role, you’ll collaborate closely with the founder and product team to define requirements, propose practical solutions, and ship features iteratively—striking the right balance between developer experience, performance, and security.
