Full job description

Who are we?

At Newcode.ai, we’re on a mission to reshape how organizations put AI to work in their day-to-day operations. In few months, we’ve moved from vision to reality—building products our clients truly love. As part of our fast-growing and highly ambitious team, you won't just drive the future of AI—you’ll help define it.

The role

You'll build features the whole way through: the FastAPI service and data work on the back, the React interface on the front. Most of what we build puts a language model in front of someone doing real work, so a typical feature might mean wiring up retrieval and an LLM call on the backend, then building the streaming, document-heavy UI that makes it usable.

We want someone who can carry a feature from idea to production without handing it over a wall. You should be at home in a Celery task and in a React component, and able to handle routine work on either side without waiting for a specialist to unblock you.

Requirements

What You'll Do

Building AI features end to end, API through UI.
Making models usable: streaming responses, real-time updates, and interfaces that handle a lot of documents without feeling slow.
Owning quality and architecture on both sides of a feature.
Pulling in our frontend or backend specialists when something needs real depth, and handling the rest yourself.

Who You Are

At least five years building and shipping fullstack work. Depth matters more to us than the number.
Comfortable on both sides for real: you can design a clean API and build a good UI on top of it.
You care how it turns out: readable code, a UI that feels right, an architecture you'd defend.
You use AI coding tools (Claude Code, Cursor, Copilot) and use them well. They make you faster; they don't write code you don't understand, and you wouldn't pass sloppy AI output in review.
Keen to go deeper on LLMs, RAG, and agents.
Fine working in a startup that shifts under you.

Experience we expect with the stack

React: 5+ years
TypeScript: 3+ years
FastAPI / Python: 3+ years
PostgreSQL
Redis: 2+ years
Tailwind CSS: 1+ year

Nice to have: Next.js, React Query, Zustand, shadcn/ui; LangChain or LlamaIndex; streaming over SSE or WebSocket.

Benefits

Why Newcode.ai?

Join a collaborative, high-energy team where your ideas are heard and your impact is real.
Help design, build, and launch products shaping the future of artificial intelligence.
Work flexibly, in English, from anywhere in the EU.

At Newcode.ai, you don’t just see the future—you help create it.
Ready to shape what’s next? Apply today and join us in building a smarter, more efficient world powered by AI.
