About the role

Pentagon Technical Services provides specialist technical and project resources to data centre and mission-critical construction clients across Europe.

• Operate and enforce permit to work systems, isolation procedures and safe systems of work on site.
• Review and approve RAMS and method statements, and run toolbox talks and site inductions.
• Support the five-stage commissioning process (L1–L5). This means keeping installation records, inspection and test documentation, and handover packs complete and accurate.
• Monitor quality, record snagging and defects, and close them out before handover.
• Track daily and weekly progress against the programme, and report progress, risks and delays to site management.
• Coordinate with other trades, the client’s representatives and commissioning teams so the works interface cleanly.
• Maintain site standards for housekeeping, safety, security and controlled access, particularly where works are in or next to live environments.
• Report incidents, near misses and unsafe conditions immediately, and support investigations.

• A recognised supervisory safety qualification: SSSTS, IOSH Managing Safely or equivalent.
• Working knowledge of permit to work systems, isolation procedures and safe systems of work.
• Understanding of the five-stage commissioning process and the documentation it requires.
• Ability to read and interrogate MEP drawings, schematics and single line diagrams.
• Fluent written and spoken English.

Desirable

• Trade background in electrical or mechanical installation.
• Experience working in Nordic or Arctic conditions.
• Experience working within or adjacent to live data centre environments.
• Norwegian language capability.
• First aid at work and appointed person for lifting operations.

Personal attributes

• Calm, practical and direct, with a strong safety-first mindset.
• Confident leading multinational teams and managing subcontractors.
• Organised, with a disciplined approach to documentation and close-out.
• Willing to work in remote locations and on a rotation pattern.
