🚀 About Mendo — and why this matters

We're living through the biggest technological shift since the internet. Generative AI is changing how people work — yet most teams barely scratch the surface, unsure how to turn the hype into real, everyday value. Closing that gap is exactly what Mendo does.

Mendo is the AI Transformation Platform for enterprise clients. Rather than adding yet another tool to the stack, we work right inside the AI tools teams already use — Microsoft 365 Copilot, ChatGPT, Gemini, Claude, and internal agents. From there, we guide people toward proven use cases, certify their skills, and give organizations a clear view of what's actually driving value.

And it's working. We support 100+ enterprise clients — including EY, PwC, Crédit Agricole, SNCF, La Poste, ENGIE, Groupe SEB, and Novo Nordisk — with 200+ use cases live, a user NPS of 64, and 3x GenAI ROI within months. We've raised €12M following our Series A and we're scaling fast.

Join us and you won't just ship software — you'll shape how leading organizations adopt the defining technology of our era, and help keep people at the center of the AI revolution rather than left behind by it. We believe humans have a vital role to play in this revolution, and we're building the platform that keeps them there.

🧭 Core mission

Make Mendo's AI work, every day. We already ship AI across the product — proprietary small language models that run on people's own devices, retrieval and classification pipelines, and the analytics that tell organizations what's actually driving value. Your job is to execute: train and evaluate the models, keep the features we've shipped healthy in production, and be the hands-on AI partner the product squads turn to when they're shaping what comes next.

You'll work alongside our CTO and the engineering squads, own the AI workstream for a product area end to end, and become its AI referent. This is an individual-contributor role with no direct reports — we need someone autonomous who ships and operates, not someone who wants to run a team.

1. Train and evaluate our models

2. Maintain what we've built

3. Brainstorm and prototype with the squads

4. Raise the bar on your scope

🧱 Tech stack

This stack is always evolving, and we're counting on you to help us evolve and improve it.
