Paris, Île-de-France pleias Temps plein

At pleias, we built the world's only world's best fully open source LLMs under 1b and created Common Corpus - the largest fully open dataset (2T tokens) - now powering 7+ sovereign European and enterprise LLMs.

Today, we're building specialised LLMs for our partners (enterprise, governments, NGOs, startups) and developing a new product for context engineering at scale.

We're looking for:

Full Stack AI Engineer

You should know: Python, modern web frameworks (FastAPI/Flask, React/Vue), ML frameworks (PyTorch/transformers), APIs & integration, Docker/containerization, cloud infrastructure basics. You've deployed AI models to production and built end-to-end ML applications.

What we care about:

  • You build things. Personal projects, open source contributions, side experiments - show us what you've made

  • You're autonomous. You see problems, you solve them. You don't wait for perfect specifications

  • You're versatile. You like working on different challenges - data pipelines, model optimizations, evaluations.

We're a small team working on hard problems. If you've been experimenting with LLMs, building agents in your spare time, or have strong opinions about how AI systems should work - we want to hear from you.
