Data Center Technician L3
Job Overview
Ce poste est ouvert aux candidats francophones ; toutefois, un niveau professionnel en anglais (écrit et oral) est requis pour collaborer avec des équipes 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. As the site transitions into production, you will continue as part of the core team supporting steady‑state operations, ensuring continuity and technical ownership across the full lifecycle of the environment.
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.
Employment Type
This position is offered as a Contrat à Durée Indéterminée (CDI) under French employment law.
