Mechanical Engineer

Data Centre | Static / Shift-Based | Permanent

-60,000 + package

This is a static, site-based role for someone who wants to get in on the ground floor of a brand-new liquid cooling system on a newly installed contract.

You''ll be working for a UK-based data centre specialist that handles design, build and maintenance under one roof. They operate across the UK, Europe, Asia-Pacific and the US, serving clients who need complex data centre infrastructure delivered without error, and their pitch is simple: one company, one team, full accountability end to end.

This isn''t a role where you''re inheriting someone else''s problems. Because the system and the contract are both new, there are no legacy issues to fix. You''ll be part of a static site team providing round-the-clock cover, working to strict health & safety and permit-to-work procedures within a live, critical environment.

What you''ll do

  • Maintain and support a brand-new liquid cooling system, with training provided.
  • Carry out planned and reactive maintenance on mechanical plant and cooling infrastructure across the data centre.
  • Monitor system performance, respond to alarms and faults, and carry out first-line diagnostics and repairs.
  • Complete routine inspections, PPMs and statutory checks in line with site procedures and manufacturer guidance.
  • Maintain accurate maintenance records, logs and compliance documentation.
  • Work to strict health & safety, permit-to-work and site access procedures within a live, critical environment.
  • Escalate and coordinate with specialist subcontractors or OEM support where required.

What you''ll need

  • Data centre experience is essential.
  • Strong mechanical engineering background, ideally HVAC, cooling systems or critical plant maintenance.
  • Comfortable working on new technology.
  • Able to work 12-hour shifts on a 4 on / 4 off pattern.
  • Methodical, safety-conscious, and confident working independently as well as part of a shift team.
  • Recognised mechanical qualification (e.g. NVQ, City & Guilds, HNC/HND) or equivalent trade background.
