Mendo.ai; France; Hybride; EUR 75 000 - 90 000; Plein temps

Résumé du poste

Mendo is the AI Transformation Platform for enterprise clients. As our first dedicated AI Engineer, you will own AI research and the features we ship across the whole company — from the proprietary language models we package into our adoption product and run on people's devices, to the analytics and AI strategy recommendations we surface in our impact product.

You will work transverse across every product and squad, set our AI direction, and stay deeply hands-on.

Qualifications

• 6+ years in ML / AI engineering, with a track record of shipping models and AI features to production.
• Strong command of LLM fine-tuning, RAG, embeddings, and evaluation (golden sets, LLM-as-judge, regression tests).
• Experience optimising AI systems for cost, latency, and quality in production.
• Solid software engineering fundamentals — you ship and operate, not just prototype.
• Comfortable in Python and able to work across a TypeScript product codebase.
• Experience with small language models (SLMs) and on-device / on-prem model deployment is a strong plus.

Responsabilités

• Drive applied AI research and turn it into features that ship across our products.
• Train, fine-tune, and evaluate our proprietary language models — including small models that run on-device.
• Define the AI roadmap and arbitrate AI decisions across product, engineering, and sales.
