Job Summary
The Group Commissioning Director is accountable for the governance, strategy and consistent delivery of commissioning across all VIRTUS data centre projects, major infrastructure upgrades and lifecycle replacement works across Europe. The role acts as the owner’s commissioning authority, ensuring that critical infrastructure is designed, installed, tested, integrated, documented and formally accepted in line with VIRTUS requirements, project specifications, operational readiness criteria, applicable legislation, ISO requirements, customer requirements and industry best practice.
The role provides dedicated data centre commissioning expertise to support new build and expansion projects, management of group-wide commissioning standards and customer engagements as required. Through the commissioning team, appointed commissioning agents, contractors and suppliers, the role will lead the commissioning lifecycle from early design commissionability reviews and factory testing through site acceptance, start-up, functional performance testing, Integrated Systems Testing, defect closure and operational handover.
The role is responsible for ensuring safe energisation, resilient system performance, clear acceptance criteria, robust issue resolution, evidence-based handover and continued improvement of the VIRTUS commissioning playbook, standards and reporting framework.
Duties And Responsibilities
The role includes but is not limited to the following:
- Own and continuously improve the VIRTUS commissioning framework, playbook and regional standards across the UK and European portfolio, ensuring clear roles, interfaces, level definitions, decision gates, acceptance criteria, escalation routes, reporting templates, evidence requirements and handover criteria.
- Build, lead and resource a high-performing regional commissioning team across the UK, Germany, Italy and other European locations, setting clear expectations, priorities and ways of working while developing capability through coaching, technical mentoring, structured development plans, knowledge sharing and succession planning.
- Lead the full commissioning lifecycle from design commissionability review through Level 1 FAT, Level 2 installation verification, Level 3 start-up and energisation, Level 4 functional performance testing, Level 5 Integrated Systems Testing, defect closure and formal operational handover.
- Ensure commissioning deliverables are planned, reviewed, evidenced and completed to the required standard, including FAT/SAT documentation, readiness checklists, test scripts, witnessing records, FPTs, IST plans, method statements, MOPs/SOPs, deficiency logs, commissioning reports and turnover packs.
- Support commissioning-related procurement, appointment and contract governance by defining scope requirements, reviewing consultant and contractor proposals, validating commissioning deliverables and ensuring contractual testing, evidence and handover obligations are clearly understood and delivered.
- Provide technical governance over critical data centre systems, including HV/LV distribution, switchgear, transformers, UPS, generators, fuel systems, batteries, mechanical cooling, chilled water plant, CRAH/CRAC/CDU units, controls, BMS/EPMS, fire and life safety systems, alarms and monitoring interfaces.
- Drive IST readiness and execution, including prerequisites, load-bank strategy, resilience scenarios, failure-mode testing, utility-loss simulations, controls integration, alarm validation, operational witnessing, defect tracking and retest closure.
- Govern customer and operational acceptance readiness by ensuring commissioning evidence, test results, risk positions, exclusions, deferred works and acceptance recommendations are clearly presented, agreed and formally recorded before handover.
- Ensure commissioning activities are delivered safely and compliantly, particularly during energisation, live testing, permits, isolations, switching, risk assessments, method statements, emergency arrangements and Health & Safety, fire, security and ISO-related requirements.
- Review design, construction and operational documentation to confirm commissionability, maintainability, testability, sequence of operations, controls logic, alarm strategy and operational readiness are embedded early in project delivery.
- Maintain commissioning KPIs, dashboards, digital tracking tools and management reporting to provide clear visibility of readiness, programme status, defects, retesting, acceptance risks, safety performance, resourcing, handover readiness, benchmarking and lessons learned.
- Lead effective collaboration with project teams, operations, engineering discipline leads, consultants, commissioning agents, contractors, vendors and customer commissioning stakeholders to align capability, resolve issues quickly and minimise programme, safety, customer and operational impact.
- Train and support engineering and operations teams on commissioning processes, test philosophy, system operation, handover expectations and operational readiness requirements.
- Use commissioning findings, operational trends, failure risks, industry best practice and lessons learned to improve data centre reliability, resilience, efficiency, power usage effectiveness and future project delivery.
- Support post-handover stabilisation by reviewing early-life operational performance, commissioning-related incidents, alarms, defects and customer feedback, ensuring lessons learned are captured and fed back into design, construction, commissioning standards and future projects.
- Undertake any other reasonable requests made by your line manager.
