Job Description:

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.

Job Responsibility:

  • Lead the commissioning of full data centre cooling infrastructure, including chillers, AHUs, CRAC/CRAH units and fan wall systems
  • Functional testing, optimisation, controls integration, documentation and client handovers
  • Work closely with advanced controls platforms including BACnet and Modbus, supporting integration with site BMS systems
  • Manage own time and represent the business on complex project sites

Requirements:

  • 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
What we offer:
  • 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
