Job Overview

Ce poste est ouvert aux candidats francophones ; toutefois, un niveau professionnel en anglais (crit et oral) est requis pour collaborer avec des quipes internationales.

The Data Center Technician L3 is a senior, hands-on role supporting the build-out and long-term operation of a new, enterprise-scale data center environment.

This position offers a unique opportunity to contribute from the ground up-beginning in a greenfield deployment phase, where you will play a key role in infrastructure build, installation, and commissioning.

You will work across server, network, and infrastructure domains, taking on complex technical tasks and acting as a key on-site resource. This is a high-impact role suited for technicians who are comfortable operating with autonomy and contributing to both building and running critical infrastructure.

You will collaborate closely with engineering and operations teams, many of whom are internationally based, making strong English communication skills (written and verbal) essential for success in this role.

This role offers continuity across both deployment and operational phases, providing a strong foundation for long-term technical growth within a critical infrastructure program. The program is designed with continuity in mind, with a focus on building a stable, high-performing team that evolves with the site over time.
