Mechanical Engineer

The Mechanical Engineer oversees the installation, commissioning and quality assurance of mechanical systems on our data center projects, and is the technical link between the French site team and our Portugal-based colleagues. This is a hands-on, site-based role requiring technical expertise and strong coordination skills.

CTS Europe France is a small team (six people in the French office) backed by CTS Group, a 2,500-person organisation with almost ten years of data center delivery. The day-to-day feel is close to a start-up – short decision lines, broad scope, processes being built – but with the accountability of a subsidiary: existing clients and partners, Group standards and accounts to give back to the Group.

Responsibilities of the Mechanical Engineer include:

· Oversee the installation and commissioning of mechanical systems, including HVAC, piping, cooling and fire suppression.

· Ensure works comply with approved drawings, specifications, French regulations and industry standards.
