Opening from Senior Authorised Person (SAP) Mechanical
Role Overview
The Senior Authorised Person – Electrical (SAP) is responsible for the safe control of hazardous energy (COHE) for electrical systems and associated infrastructure on site. The role focuses on the implementation, management, and governance of electrical Safe Systems of Work (SSoW) across complex, high-risk environments such as data centres and multi-fuel power generation facilities.
The SAP will coordinate closely with electrical and mechanical Authorised Persons, vendors, client and vendor commissioning managers, and health & safety teams to ensure all electrical activities are planned, executed, and reinstated safely and compliantly.
Systems under the SAP's control may include, but are not limited to:
High Voltage (HV) and Medium Voltage (MV) distribution systems Low Voltage (LV) distribution systems Transformers, switchgear, and protection systems Generators and associated synchronisation systems Uninterruptible Power Supply (UPS) systems Battery Energy Storage Systems (BESS) Power Monitoring Systems (PMS) Building Management Systems (BMS) and Electrical Monitoring Systems (EMS) Emergency Power Off (EPO) systems Earthing and lightning protection systems Data centre critical power infrastructure
Key Responsibilities
Act as the Senior Authorised Person for electrical systems, managing and enforcing Global Commissioning's Safe Systems of Work. Implement and control electrical isolations, lock-out/tag-out (LOTO), switching operations, proving dead procedures, testing, and safe reinstatement. Issue, manage, suspend, and cancel Electrical Permits to Work and associated safety documentation. Review and approve Risk Assessments and Method Statements (RAMS) for electrical works. Plan, coordinate, and supervise HV/MV/LV switching activities. Oversee pre-functional testing, electrical energisation, protection testing, and commissioning readiness activities. Attend and contribute to commissioning, coordination, and safety meetings. Coordinate electrical commissioning activities with mechanical, controls, and automation teams. Attend and support Functional Performance Testing (FPT) and Integrated Systems Testing (IST) of critical systems. Carry out final inspections and "white glove" reviews prior to system handover. Ensure compliance with site safety procedures, electrical standards, and applicable legislation. Maintain effective communication between contractors, vendors, and client stakeholders. Support incident response, emergency situations, and high-risk operations when required.
Leadership & Management
Provide leadership and supervision to electrical teams, contractors, and subcontractors. Manage complex and high-risk electrical activities in live or operational environments. Demonstrate strong decision-making under pressure, particularly during switching operations, isolations, energisations, fault conditions, and system reinstatements. Promote a strong safety culture and proactive hazard identification.
Qualifications Essential
Completion of a recognised electrical trade apprenticeship or equivalent hands-on electrical qualification. CSCS / Safe Pass. SMSTS or SSSTS. Appropriate HV Authorised Person/Senior Authorised Person certification or demonstrable experience operating under an electrical safety rules system.
Desirable
HNC, HND, or BEng (Hons) in Electrical Engineering, Power Engineering, or Building Services Engineering. Certified Electrical AP/SAP training. IOSH Managing Safely or NEBOSH qualification.
Skills & Technical Knowledge
Extensive hands-on experience with electrical power systems, plant, and equipment.
Proven expertise in electrical isolations, LOTO, switching operations, and hazardous energy control.
Strong working knowledge of:
HV, MV, and LV power distribution systems Generators, synchronisation systems, and emergency power systems UPS systems and battery installations Transformers, switchgear, protection relays, and metering systems Electrical infrastructure associated with power generation and data centres
Sound understanding of commissioning processes and documentation (Cx Plans, FAT, SAT, IST, ITPs).
Familiarity with electrical safety rules, arc flash mitigation, and safe switching procedures.
Strong understanding of Irish, UK, and EU health, safety, and environmental legislation, including HSA requirements.
Fully proficient in Microsoft Office applications.
