• 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
