We’re recruiting a Commissioning Engineer to join a specialist OEM team delivering large-scale data centre and critical cooling projects across the UK, with occasional European project support.
This is a commissioning-led role, not service. You’ll take ownership of complex cooling systems from first power-up through to final sign-off on high-value, mission-critical sites.
What You’ll Be Doing
You’ll lead the commissioning of full data centre cooling infrastructure, including chillers, AHUs, CRAC/CRAH units and fan wall systems. The role covers functional testing, optimisation, controls integration, documentation and client handovers.
Work is predominantly UK-based (London and South East heavy), with planned project travel rather than reactive call-outs. You’ll work closely with advanced controls platforms including BACnet and Modbus, supporting integration with site BMS systems.
This is a mobile, autonomous position where engineers are trusted to manage their own time and represent the business on complex project sites.
What You’ll Need
- Proven commissioning experience at sign-off level with chillers, AHUs and CRAC/CRAH systems
- Strong controls knowledge, including BACnet and Modbus
- Previous data centre or critical cooling commissioning experience
- Comfortable working independently on complex, live or near-live sites
- Confident producing commissioning documentation and leading client handovers
- Full UK driving licence
- Willingness to travel, including occasional European projects
Salary, Earnings & Package
£48,000 – £52,000 base salary (DOE), structured to deliver strong total annual earnings. The package includes:
- Door-to-door travel paid
- Time-and-a-half paid on all hours worked beyond 40 per week (including travel)
- Consistent, predictable overtime due to long-term project delivery
- Pension contributions calculated on full earnings
- Company vehicle with private use, laptop, tablet, tools and high-spec equipment
- Paid travel, accommodation and expenses
- Ongoing OEM training on critical cooling systems and controls
For engineers comfortable with site-based project work, the structure delivers earnings well beyond the headline base, alongside stability and high-quality projects.
