Critical Systems Technician - Data Centers & Lab Infra

The NBI Partnership (NBIP) provides non-scientific services to research institutes based on the Norwich Research Park, a globally recognised centre for bioscience innovation.
The park is home to leading research institutes, including the John Innes Centre (JIC), Quadram Institute Bioscience (QIB), Earlham Institute (EI) and The Sainsbury Laboratory (TSL), supporting cutting-edge research in food security, health and environmental sustainability. NBIP provides the facilities management (FM) services to the JIC's, TSL's and EI's estates and buildings.
The Critical Services Technician is a pivotal role within the Facilities team at NBIP, responsible for maintaining, repairing, monitoring and ensuring the safe and efficient operation of critical building infrastructure and essential services. With a mechanical bias, the post-holder will specialise in the maintenance, servicing and repair of pressure systems and pressure equipment, laboratory autoclaves, pumps, plate heat exchangers and associated pipework and plant. They will also support Horticulture Controlled Environment Rooms (CERs), Data Centres, Energy Centre equipment, Combined Heat and Power (CHP) units, Medium Temperature Hot Water (MTHW) systems, Life Safety systems and Building Management Systems (BMS), with the electrical and controls competence to work independently across these systems.
The post-holder will have expertise in technical fault diagnosis, preventive maintenance and reactive repairs, ensuring all critical equipment performs at optimal levels. They will also play a key role in supporting compliance with statutory regulations, safety standards and operational best practice.
Working closely with the wider Facilities Maintenance Operations Team, the Critical Services Technician will ensure the availability and reliability of critical systems that support scientific research and operational needs at NBIP. This role requires a proactive, solution-focused approach, contributing to continuous improvement and operational resilience. The post-holder will be expected to deputise for the Critical Services Supervisor.
