Fullstack Engineer - React.js - Next.js

As a Junior Fullstack Engineer (Freelance), you'll work alongside our engineering team to build features across our platform, from React components and UI to API endpoints and backend logic. You'll get exposure to a modern stack with deep AI integration, learn fast from experienced engineers, and contribute to a product with real users and real impact.

You implement product features end-to-end under the guidance of senior engineers, from React components and UI to API endpoints and backend logic.
You participate in technical discussions and code reviews, first as a learner, increasingly as a contributor.
You contribute to our AI-powered features: implementing LLM integrations, working with embeddings, and helping build out RAG patterns.
You write clean, tested, and well-documented code, and you take ownership of what you ship.
You work closely with our CTO and senior engineers, take feedback well, and ramp up fast.
You work with the latest AI tools (e.g. Cursor, Claude Code) and our modern stack.

Experience with React.js and Next.js.
You need to have a good understanding of current UI / UX standards.
Experience in the T3-Stack (especially Prisma, TailwindCSS and TypeScript).
