Senior Service Engineer

Job title : Senior Service Engineer

Job Description

• The C&I Operations Engineer/Lead owns the full operational lifecycle of Husk's Commercial & Industrial (C&I) solar portfolio in Nigeria - from commissioning handover (HOTO) through day-to-day service delivery, maintenance execution, customer relationship management, and performance reporting. 
• The role is the single operational accountability point for all active C&I sites, ensuring asset uptime, contracted SLA fulfilment, and customer satisfaction are consistently achieved. 
• This is a hands-on, field-anchored position requiring deep technical competence combined with the commercial maturity to manage high-value client relationships directly. 
• As the C&I portfolio scales, this role will anchor the foundation of Husk Nigeria's C&I Operations function and is expected to evolve into a team leadership position.

Key Responsibilities
Asset Operations & Uptime Management:

• Own the operational performance of all active C&I sites - ensuring maximum plant availability and energy delivery in line with contracted SLAs.
• Monitor daily site performance data and act on anomalies proactively before customer escalation.
• Maintain accurate site logs, operational parameters, and energy flow records for each C&I asset.

Preventive Maintenance (PM):

• Design and execute structured Preventive Maintenance programmes for all C&I sites in accordance with OEM specifications, IEC standards, and Husk's Technical & Operating Standards.
• Schedule and mobilise field technicians, third-party service vendors, and spare parts to execute PM on time and within budget.
• Maintain PM completion records, checklists, and compliance documentation for all sites.
• Conduct periodic site inspections to validate PM quality and identify emerging failure risks.

Corrective Maintenance (CM) & Fault Resolution:

• Serve as the primary technical response owner for all unplanned faults, equipment failures, and site outages across the C&I portfolio.
• Lead fault diagnosis, root-cause analysis, and resolution - hands-on where required, coordinating specialist support for complex faults.
• Manage escalation protocols: ensure critical faults are acknowledged within 1 hour and resolved within agreed MTTR targets.
• Track open corrective actions, prevent repeat failures, and close out tickets systematically through the maintenance management system.

Customer Relationship Management (Post-HOTO):

• Serve as the primary operational point of contact for all C&I customers after commissioning handover - managing the day-to-day relationship with professionalism and responsiveness.
• Conduct regular service review meetings with clients; present performance reports, address concerns, and maintain trust throughout the PPA lifecycle.
• Manage customer complaints and service requests within defined SLAs - ensuring formal logging, root-cause communication, and satisfactory resolution.
• Proactively communicate planned maintenance schedules, outages, and system changes to affected customers in advance.
• Identify and escalate any commercial, contractual, or relationship risks to the Senior Director in a timely manner.

Reporting & Performance Visibility:

• Prepare and submit weekly site performance reports and monthly Operations Summaries covering uptime, Solar generation, preventive/corrective maintenance status, usage and customer satisfaction.
• Contribute C&I operational data and narrative to the Operations Dashboard and Monthly Performance Reviews (MPR).
• Maintain accurate records of all service events, faults, vendor activities, and customer interactions.
• Flag performance risks and operational deviations proactively with recommended corrective actions.

Vendor & Contractor Management:

• Manage C&I-specific service vendors, OEM partners, and field contractors - tracking SLA compliance, mobilisation timelines, and quality of work.
• Validate vendor deliverables, certify work completion, and process invoices accurately and on schedule.
• Support procurement of spare parts, consumables, and specialist services in alignment with approved operational budgets.

HSE & Regulatory Compliance:

• Enforce HSE standards at all C&I sites - conducting safety inspections, ensuring compliance, and promoting a zero-incident culture.
• Maintain and update commissioning records, HOTO documentation, and regulatory compliance files for all active sites.

Commissioning Support & HOTO:

• Support the Projects team during the commissioning phase of new C&I installations — participating in testing, verification, and snag resolution.
• Own the formal HOTO process from Projects to Operations: validate completeness of commissioning documentation, site readiness, and client acceptance before assuming operational responsibility.
• Ensure all new sites are fully onboarded into the operational management system at HOTO — with monitoring connectivity, PM schedules, and vendor coverage confirmed.

Qualifications

• Bachelor's Degree in Electrical Engineering, or a closely related engineering discipline. COREN registration (or active pursuit) is an advantage.
• Relevant technical certifications in large solar PV systems, battery storage are a strong plus.
• Minimum 5 years of hands-on experience in operations, maintenance, or technical service delivery for large-scale solar PV, hybrid energy, or C&I power systems.
• Demonstrated experience managing O&M for installations of >200 kWp capacity, including corrective and preventive maintenance execution.
• Proven ability to manage multiple sites simultaneously, with accountability for uptime, SLAs, and client satisfaction.
• Experience managing service vendors, field technicians, and third-party contractors.
• Prior exposure to BESS (Battery Energy Storage Systems) and AC-coupled hybrid configurations is preferred. Strong working knowledge of solar PV systems, BESS, hybrid inverters, AC/DC distribution, and protection systems.
• Proficiency in reading and interpreting single-line diagrams, protection coordination schemes, and system performance data. Familiarity with energy monitoring platforms.
• Solid understanding of relevant standards: IEC 62446, IEEE 1547, ANSI relay codes, and Nigeria electrical safety regulations.
• Hands-on, self-starting operator who can diagnose and resolve faults independently - without waiting for direction.
• Strong customer-facing presence: professional, calm under pressure, and capable of managing high-value client relationships.
• Structured thinker who reports with clarity, escalates with precision, and documents thoroughly.
