Microsoft Office & AI Applications Engineer

Project overview

Context

As part of a digital transformation program and the integration of artificial intelligence within Microsoft Office collaborative tools, we are looking for a Microsoft Office & AI Applications Engineer / Technical Consultant.

The consultant will work within a team dedicated to integrating generative AI solutions in a secure, On-Premise hosted office environment.

The objective is to study, integrate, and deploy Microsoft Office plugins that enable interconnection with internally hosted LLMs, particularly models like Mistral AI.

A first plugin, Red Ink, has been identified and will require in-depth analysis to create an MVP (Minimum Viable Product), before preparing for its industrialization and large-scale deployment.
