Lead Maintenance M&E Power Engineer / Site Facility Manager at International Facilities Services Limited - IFS

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), fire detection and suppression (including FM-200 clean agent systems), passenger lifts, stage elevators, dumbwaiters, and UPS systems.
• Review and approve all M&E PPM schedules and maintenance outputs; ensure PPM completion rates remain above 95% and that all asset maintenance records are accurately maintained in the CMMS.
• Manage the BMS—setpoints, alarm thresholds, trend logging, and scheduled operations; use BMS data proactively to identify plant deterioration before it becomes a failure.
• Lead the technical response to all building services emergencies—you are the first senior engineer called at any hour when a critical system fails during an event.
• Interface with all OEM technical representatives—Daikin, CAT, Schneider, ABB, or equivalent—during commissioning, warranty inspections, and specialist maintenance visits; review and approve their work and maintain records of all OEM service interventions.

Site Management & Leadership:

• Function as the overall Site Manager for the IFS FM operation at the facility—the single point of accountability for technical performance, team management, client relationship management, statutory compliance, and health and safety on-site.
• Lead, manage, and develop the on-site engineering and technical team—generator, HVAC, electrical, plumbing, and civil technicians—through structured supervision, performance review, on-the-job coaching, and formal training coordination.
• Manage and supervise all subcontractors and specialist service providers on-site—review method statements and risk assessments, issue Permits to Work, conduct inductions, and verify quality of completed works before sign-off.
• Serve as the primary IFS technical representative in all client-facing interactions—attend management meetings, respond to technical queries with confidence and precision, and proactively communicate planned works, system status, and risks to the client before they become issues.
• Prepare and present the monthly technical performance report—covering PPM completion, reactive works, energy consumption, diesel usage, fault trends, asset condition, and forthcoming planned works—to IFS management and the client.
• Own the site's Health, Safety & Environmental compliance—enforce safe systems of work, maintain the H&S file, conduct and review risk assessments, investigate incidents, and ensure full compliance with Nigerian H&S legislation and IFS company safety standards.

Method of Application
Qualifications, Experience & Person Profile:

• B.Eng or B.Sc in Electrical Engineering, Mechanical Engineering, or Electrical/Mechanical Engineering from an accredited Nigerian or internationally recognised university.
• Full registration with COREN (Council for the Regulation of Engineering in Nigeria) as a registered engineer—this requirement is absolute and non-negotiable.
• 7–10 years post-qualification engineering experience, with at least 3 years in a maintenance engineering role at a complex, large-scale facility—government, hospitality, industrial, or critical infrastructure environments are preferred.
• Demonstrable, hands-on technical experience with all of the following: grid-connected HV/LV electrical systems; diesel generator plant of 500 KVA and above; ATS/AMF automatic transfer and mains failure systems; solar PV/hybrid inverter systems; and UPS/battery systems. You must be able to describe specific installations you have personally managed, not merely observed or supervised from a distance.
• Authorised HV switching competence—ability to prepare and execute HV switching schedules safely and in compliance with all applicable regulatory requirements.
