# Founding AI Engineer

- **Company:** Eu Recruit
- **Location:** Paris, France
- **Experience:** Experienced
- **Contract:** Permanent contract
- **Skills:** Artificial Intelligence, Cloud Computing, Continuous Integration, PostgreSQL, Retrieval-Augmented Generation, Build Server
- **Published:** October 8, 2026

## About the Role

We are looking for engineers with at least three years of professional software engineering experience, supported by one or both of the following:

 * An exceptional academic background: a degree from a top-five institution in France, or an internationally comparable leading institution.
 * A standout professional track record: experience as a CTO, technical lead or founding engineer at a technically impressive startup, or a strong engineering career at companies such as Palantir, Doctolib, Helsing, Aircall, Pigment or Uber.

You should also bring:

 * Strong software fundamentals. You understand what happens beneath the abstractions and can design and debug complex systems.
 * Sound data modelling judgement. You think carefully about entities, relationships and schemas, and have built models that support evolving product requirements.
 * Practical applied AI experience. You have shipped LLM, RAG or agent-based systems for real users and understand their limitations.
 * Evidence of delivery. You can explain what you personally built, the decisions you made and what you learned when things broke in production.
 * Ownership and accountability. You drive work through to completion, communicate risks early and deliver without constant supervision.
 * An entrepreneurial mindset. You are comfortable with ambiguity, move quickly, welcome feedback and understand the intensity and hours involved in an early-stage company.
 * Independent judgement. You use AI development tools effectively while retaining responsibility for the quality and originality of your work.
 * Excellent written and spoken English. French is a plus.

## Description

As a Founding AI Engineer, you will work directly with the CTO to design, build and own core systems. Decisions you make in the coming months will shape how the product develops over the coming years.

This is a hands-on engineering role combining applied AI, data modelling and production software development.

What you will do

 * Model factory operations. Build the context graph connecting processes, products, machines and procedures-the core data structure underpinning the platform.
 * Build AI agents. Develop systems that make factory expertise accessible and help teams answer questions, troubleshoot issues and improve operations.
 * Own data ingestion. Turn videos, documents and machine data into clean, structured information that AI systems can use reliably.
 * Make retrieval work. Design how knowledge is chunked, indexed, retrieved and delivered to agents.
 * Ship production systems. Take ownership from technical design through implementation, deployment and ongoing improvement.
 * Set engineering standards. Help establish the tooling, architecture and development practices adopted by future hires.
