Electrical Supervisor

ABOUT COLWIN

We are a leading, engineering-driven operations and maintenance partner for flexible and hybrid power generation infrastructure across Ireland, the UK and Europe. We support mission-critical assets with a focus on safety, reliability and performance, drawing on deep technical expertise and a delivery culture built for long-term, high-availability operation.

We combine engineering intelligence with operational discipline to deliver high-reliability services at scale. Building on a strong foundation in flexible thermal generation, we are expanding our capability across evolving sustainable hybrid and storage technologies and progressing toward campus-wide data centre and energy O&M solutions - supporting controlled growth through technical credibility and a safety-first approach.

MAIN TASKS AND RESPONSIBILITIES:

• Plan, coordinate, and oversee predictive, preventive, and corrective maintenance activities for all electrical systems, switchgear, distribution networks, control systems, and protection equipment.
• Lead, supervise, and mentor the team of electrical technicians and trainees, allocating resources, setting priorities, and managing team performance and development.
• Responding to out of hours events (when required), secondary on call system (SOC).
• Monitor electrical operational parameters (voltage, current, power factor, frequency) and lead troubleshooting; make autonomous decisions to resolve electrical anomalies and minimize downtime.
• Ensure strict adherence to QAS and HSE procedures, quality standards, and industry best practices, with a strong emphasis on electrical safety.
• Manage electrical tools, test equipment, calibration instruments, and spare parts inventory, including supply chain coordination and stock control.
• Diagnose electrical faults by reviewing single-line diagrams, wiring schematics, protection relay settings, and test results, and independently validate and approve repair strategies.
• Respond to plant electrical alarms and emergencies, directing the team in restoration efforts.
• Enforce Permit to Work systems and Lockout/Tagout (LOTO) procedures, with specific attention to safe electrical isolation; review and approve isolation permits and work documentation for completeness.
• Oversee and audit the logging of maintenance activities in the Computerized Maintenance Management System (CMMS), ensuring data accuracy for operational reporting.
• Oversee the safe isolation, de-energization, and earthing/grounding of electrical equipment, championing safety culture within the team.
• Competent to operate and maintain HV (High Voltage) systems (typically 15 kV to 110 kV), acting as the responsible person for HV switching and isolation.
• Prepare, review, and approve Method Statements and Risk Assessments (RAMS), assessing electrical risks (arc flash, shock hazards, etc.) from a managerial perspective.
• Prepare, review, and approve switching plans/SOPs/EOPs.
• Identify system anomalies, lead root-cause analysis, and drive continuous improvement initiatives, presenting data-driven recommendations to upper management.

QUALIFICATIONS / TRAINING / EXPERIENCE:

• EQF Level 6 / NFQ Level 8 (or higher) in Electrical Engineering, Electrical Power Systems, or a closely related discipline.
• Minimum 5 years hands-on experience in maintaining industrial electrical systems (switchgear, transformers, motors, generators, VSDs, protection relays, control panels, distribution networks).
• Minimum 2 years of proven experience in a supervisory or team leadership role, managing electrical technicians and/or sub-contractors in an industrial environment.
• HV training provided by a recognised and accredited training provider i.e. ‘City & Guilds’.
• Advanced capability in electrical testing, diagnostics, and fault-finding on low, medium, and high voltage systems.
• Demonstrated ability to manage time-sensitive tasks and prioritize workloads effectively.
• Proficient in reading and interpreting complex single-line diagrams, wiring schematics, loop drawings, protection logic diagrams, and technical documentation.
• Proficient in CMMS software for managing work orders and logging maintenance history, including advanced reporting and analytical functions.
• Experience in operation and maintenance activities within an industrial environment (power generation, heavy industry, or oil & gas).
• Thorough knowledge of safe work practices, including electrical isolation, LOTO, arc flash protection, earthing/grounding, and Permit to Work systems.
• Working knowledge of British Standards and European health & safety regulations.
• Fluency in English (written and spoken).
• Understanding of Portuguese is optional but valued.
• Availability and authorisation to work in Ireland is essential.

SKILLS:

• Strong understanding of power plant electrical equipment terminology, protection systems, operational procedures, and system interdependencies.
• Strong leadership skills – comfortable directing others, providing clear instructions, and holding peers accountable in a respectful manner.
• Self-motivated and proactive – takes ownership and initiative without waiting for instructions.
• Decisive under pressure – able to make sound technical decisions independently during electrical faults/breakdowns.
• Strong analytical and critical problem-solving skills, with experience in root-cause analysis and protection coordination.
• Excellent communication and coordination skills – capable of bridging the gap between technicians and senior management.
• Good knowledge of plant architecture, evacuation plans, safety points, and environmental control systems.
• Knowledge of instrumentation engineering design, such as P&ID, Instrument Specs/ Data Sheets
• Competency in tools like Microsoft Office Suite (Word, Excel, PowerPoint), Google Workspace, and email management platforms
• Commitment to environmental protection procedures and regulatory compliance.
• Familiarity with alarm systems, SCADA interfaces, protection relay systems, and emergency protocols in power plants or heavy industrial sites.
• Administrative aptitude – comfortable with report writing, data analysis, performance tracking, and maintenance KPI monitoring.
• Proficiency in the use and care of common and specialized electrical test equipment (multimeters, insulation testers/meggers, primary/secondary injection test sets, oscilloscopes, thermal imaging cameras, power quality analysers).
