Lead Maintenance M&E Power Engineer / Site Facility Manager

Lead Maintenance M&E Power Engineer / Site Facility Manager

• Job Type Full Time
• Qualification BA/BSc/HND
• Experience 7 - 10 years
• Location Lagos
• Job Field Engineering / Technical

About the Role

• We are looking for a rare breed—a competent power engineer who commands a room through competence, not title, who will be the single point of technical authority at our client’s high-profile facilities, managing a power infrastructure that spans national grid supply, a utility-scale solar hybrid system, multiple large-capacity diesel generators (3 units of 2MW), fully automated ATS/AMF switching, and critical building services across hard and soft services
• Must be an experienced maintenance engineer with the technical depth to diagnose a fault and be able to lead the team to fix it; who does not wait to be told. He walks the plant, reads the BMS, spots the trend before it becomes a trip, and acts on it.
• Must command respect from the team and the client through your knowledge, your calmness under pressure, and your proven track record—not through hierarchy alone. And can write a clear, professional technical report and present it with confidence to a boardroom. You can also pull on overalls and get into a generator room. On this site, failure is not an option!
• The Lead M&E Engineer/Site Manager will serve as the senior technical authority on-site, responsible for ensuring operational reliability, leading technical teams, managing critical incidents, and providing confident, precise decision-making and technical leadership across all building systems.
• This is not a Desk role.

Power Systems—Core Responsibility Area

Daily Operational Management:

• Manage and optimise the integrated power supply architecture—national grid intake, solar PV/hybrid inverter system, diesel generator sets, and battery/UPS backup systems—ensuring seamless, uninterrupted power delivery across all facility zones at all times.
• Oversee ATS/AMF panel operation—verify automatic changeover logic, test transfer times, and manually intervene where required; ensure all changeover sequences are logged and any anomalies investigated and resolved before the next event.
• Monitor and manage the solar hybrid system—inverter performance, battery state of charge, grid-tie logic, and export/import parameters; interpret system data logs and optimise dispatch strategy to minimise diesel consumption and maximise solar utilisation.
• Oversee HV/LV electrical distribution—MCC panels, distribution boards, busbar systems, power factor correction equipment, harmonic filters, and earthing/bonding; carry out or directly supervise all HV switching operations in compliance with a formal switching schedule and Permit to Work system.
• Plan, schedule, and directly supervise generator PPM—oil and filter changes, load bank testing, cooling system checks, fuel system inspection, governor calibration, injector servicing, turbocharger inspection, and battery maintenance—across all CAT units on-site.
• Manage diesel fuel procurement, storage, consumption tracking, and stock management; maintain fuel reconciliation records and raise procurement requests ahead of all critical event periods.

Technical Leadership & Engineering Judgement:

• Conduct root cause analysis for all electrical faults, power anomalies, and unplanned outages; produce a written investigation report with corrective and preventive actions for every significant event.
• Review and approve all electrical maintenance work carried out by junior engineers and subcontractors—no electrical work on this site proceeds without your authorisation and sign-off.
• Identify energy optimisation opportunities—load profiling, demand-side management, power factor improvement, and solar dispatch scheduling—targeting measurable reductions in diesel consumption and grid import costs year-on-year.

Building Services & M&E Systems Management:

• Provide technical oversight across all M&E building services—HVAC (Daikin VRV systems, chiller plant, AHUs), hydraulics (chilled water, condenser water, domestic water, sewage), f
