Mechanical Commissioning Engineer
- Data Centers

We’re proud to be partnering with a Global Engineering Firm at the forefront of mission-critical infrastructure delivery, to recruit a Mechanical Commissioning Engineer
. This is an excellent opportunity to join a high-performing commissioning team delivering complex mechanical systems across cutting-edge data centre environments.

The Role

As the Mechanical Cx Engineer, you’ll support the full commissioning lifecycle, from design review through to functional testing and client handover, working alongside senior engineers while taking ownership of key site activities.

Key responsibilities include:
  • Functional testing using specialist instrumentation
  • Factory acceptance testing (FAT) attendance
  • Reviewing designs against client performance goals
  • Reporting system performance & technical issues
  • Coordinating with project teams & contractors

You’ll gain exposure to a wide range of systems including chillers, cooling towers, CRAC units, generators, boilers, BMS/PLC controls, fire systems, hydronics, and more.

About You

We’re keen to speak with candidates who have:

  • Mechanical Engineering degree or relevant commissioning experience
  • Strong mechanical systems knowledge
  • Experience with BMS / controls (advantageous)
  • Familiarity with ASHRAE or BCxA guidelines (desirable)
  • A proactive, client-facing mindset
Travel
  • Nationwide travel typically 50–75% (project dependent) but candidates local to job sites will be kept local.
Why Apply?
  • Work on high-profile hyperscale data centre projects
  • Join a globally recognised engineering organisation
  • Strong career progression in mission-critical commissioning
  • Comprehensive benefits package (including overtime over 40 hours)
  • Exposure to industry-leading technology & facilities

If you’re a commissioning professional looking to step into a global platform delivering complex, high-impact projects, we’d love to hear from you.
