Role Overview The Technical Manager (Mechanical) will play a key role within the Technical Delivery Team, supporting commissioning activities across all project phases in fast-paced, mission-critical data centre environments. This role is primarily focused on mechanical systems (e.g. HVAC, critical cooling, fuel systems, and associated infrastructure) and the development of Level 0 (L0) deliverables, ensuring consistency, quality, and technical excellence across the business. Working both remotely and in support of site teams, the role will contribute to commissioning strategy, support design assurance, drive standardisation of commissioning delivery, and provide expert technical guidance during complex testing and troubleshooting scenarios. The role will also incorporate duties aligned to a Commissioning Consultant (CxC), including input into sustainability-led commissioning processes (e.g. LEED, BREEAM), with responsibility for ensuring commissioning deliverables meet both client and certification requirements. The successful candidate will collaborate closely with internal teams, clients, and project stakeholders to ensure commissioning outcomes align with programme, safety, performance, operational, and compliance objectives.
