Founding Engineer

This is an early-stage, VC-backed startup reinventing how large enterprises modernise their core systems.

The goal is to create a unified ontology that understands enterprise data, code, and processes – enabling automation, system modernisation, and AI-driven workflows across large organisations.

The team is small, technical, and moving fast. This is a true founding-stage environment, based on-site in Paris.

What you'll do

• Design and implement the core enterprise knowledge graph connecting data, codebases, and business processes
• Architect systems that integrate heterogeneous enterprise applications into a unified control layer
• Build GenAI-powered workflows that operate on top of this ontology
• Turn forward-deployed prototypes into reusable, scalable product components
• Develop robust evaluation frameworks and infrastructure to ensure reliability at enterprise scale
• Design secure deployments, including on-prem environments with strict compliance requirements

What you'll need

• Strong academic background from a top-tier engineering school
• Excellent programming skills in Python, Java, or Go with strong system design fundamentals
• Experience modelling complex systems (schemas, ontologies, metadata layers, knowledge graphs)
• Practical experience integrating LLMs or GenAI workflows into production systems (RAG, embeddings, prompt design)Comfort translating ambiguous strategic vision into concrete technical architecture
• Bias for action and full end-to-end ownership
