Work closely with mechanical counterparts (cooling, BMS, etc.) to ensure fully integrated solutions
Liaise with existing data centre specialists to review progress and optimise project outputs
Collaborate with structural and architectural teams within a broader design environment
Support the growth of the team, including helping to recruit and develop M&E engineers
