The Opportunity

We are seeking an experienced Electrical Commissioning Engineer to support the delivery of a major hyperscale data centre development in Kouvola, Finland.

Working as part of an established commissioning team, you will play an important role in coordinating, witnessing and verifying the commissioning of critical electrical infrastructure, ensuring systems are tested safely and delivered in accordance with project specifications, quality standards and programme requirements.

The position involves working closely with electrical subcontractors, specialist equipment vendors, commissioning management, QA/QC teams and Authorised Persons (APs) to ensure a structured approach to testing, energisation and final system handover.

This opportunity would suit an electrically biased commissioning professional with previous experience delivering technically complex construction projects, ideally within hyperscale data centres or comparable mission‑critical environments.

Key Responsibilities

Electrical Commissioning & Testing

• Coordinate and oversee electrical commissioning activities across the project, ensuring work is completed in line with approved procedures and commissioning schedules.
• Support the commissioning process across Levels 1–5, including equipment inspections, pre‑functional checks, start‑up, functional performance testing and integrated systems testing (IST).
• Witness and verify commissioning activities undertaken by electrical subcontractors, OEMs and specialist vendors.
• Support testing and commissioning of critical electrical systems, including LV/MV switchgear, transformers, UPS systems, standby generators, PDUs, distribution boards and associated protection systems.
• Assist with FAT, FWT and SAT activities, ensuring testing outcomes and associated documentation meet project requirements.
• Coordinate with Authorised Persons and relevant site teams to ensure safe energisation, isolation and switching procedures are followed.
• Identify technical defects, installation issues and commissioning failures, supporting troubleshooting and corrective actions through to resolution.

Programme Delivery & Coordination

• Monitor commissioning progress against agreed project milestones, identifying delays, constraints and potential risks to delivery.
• Work alongside Commissioning Managers, Construction Managers and MEP teams to ensure systems are ready for testing and handover.
• Participate in daily coordination meetings and weekly commissioning progress reviews.
• Liaise with vendors and subcontractors to coordinate testing activities, resource availability and commissioning priorities.
• Identify dependencies between electrical, mechanical and controls systems that could affect commissioning readiness.
• Support the planning and coordination of integrated testing activities involving critical power, cooling, BMS and EPMS infrastructure.

Quality, Documentation & Handover

• Review commissioning method statements, test procedures, inspection records and commissioning scripts before execution.
• Maintain accurate commissioning records, progress trackers, test results and equipment status documentation.
• Coordinate with QA/QC teams to verify installation quality and ensure outstanding construction defects are addressed before commissioning.
• Monitor commissioning tagging, system completion status and outstanding punch‑list items.
• Support the preparation and review of commissioning dossiers, test certificates, as‑built documentation and handover packages.
• Ensure commissioning activities comply with project specifications, relevant electrical standards and established quality procedures.
• Assist with final system verification, client witnessing and commissioning sign‑off.

Health, Safety & Compliance

• Promote a strong safety culture throughout all commissioning activities.
• Ensure compliance with site‑specific EHS procedures, permit‑to‑work systems and electrical safety requirements.
• Work closely with AP/SAP teams to maintain safe working conditions during testing and energisation.
• Identify commissioning‑related risks and ensure appropriate controls are implemented before testing begins.

Experience & Qualifications

• Electrical Engineering, Building Services Engineering or relevant electrical trade qualification.
• Minimum 5 years' experience in electrical commissioning within construction or major engineering projects.
• At least 3 years' experience in electrical testing, inspection and verification.
• Strong technical knowledge of LV/MV electrical distribution systems, with HV exposure advantageous.
• Previous experience coordinating electrical vendors, subcontractors and commissioning activities on site.
• Familiarity with commissioning procedures, testing documentation and electrical safety practices.
• Ability to interpret electrical schematics, single‑line diagrams, technical specifications and commissioning documentation.
• Strong organisational, communication and technical problem‑solving skills.
• Ability to work independently within a multidisciplinary project delivery team.
• Good understanding of EHS requirements in live construction and commissioning environments.
• Previous commissioning experience on hyperscale or colocation data centre developments.
• Understanding of L1–L5 commissioning processes and integrated systems testing.
• Experience commissioning UPS systems, generators, switchgear, transformers and critical power distribution infrastructure.
• Knowledge of BMS/EPMS interfaces and electrical system integration.
• Experience working alongside AP/SAP teams during energisation and switching activities.
• Previous project experience in Finland or elsewhere in the Nordics.
• Familiarity with structured commissioning handover and client witnessing procedures.
