Job Title: Operations & Maintenance Assurance Manager - Instrumentation & Controls

Location: Lekki, Lagos
Employment Type: Contract
Reports to: Head of Maintenance / Project Management

Job Purpose

• Provide independent assurance and technical governance for instrumentation C control (ICC) operations and maintenance across a large petroleum refinery.
• Ensure instrument and control- system integrity, reliability and compliance with company standards, functional safety requirements and regulatory expectations.
• Lead CMMS/master-data governance for ICC assets, assurance of calibration and testing regimes, turnaround readiness assurance, contractor competence assurance and continuous improvement to reduce risk and maximise plant availability.

Key Responsibilities

• Design, lead and deliver the ICC maintenance assurance programme aligned with corporate governance, Process Safety Management (PSM) and asset-management objectives.
• Carry out regular assurance reviews, audits and health checks of ICC maintenance processes (planning, scheduling, execution), calibration regimes, loop-checks, DCS/SIS change management and instrument integrity programmes. Produce clear findings with risk ratings and ensure timely closure of corrective actions.
• Own CMMS master-data governance for ICC assets: validate asset hierarchy, instrument register, tag data, BOMs, PM/calibration definitions, failure codes, spares linkage and workorder quality. Drive improvements in PM/calibration compliance, backlog control and data-driven decision making.
• Provide independent assurance for turnaround/shutdown readiness and execution for ICC scope: scope verification, instrument workpack quality, isolation and lockout procedures for instrumentation, spares C test-equipment staging, vendor readiness, loop testing, SAT/FAT and post-turnaround close-out.
• Assure calibration and testing programmes: calibration intervals and traceability (ISO 17025 awareness), calibration lab QA, instrument accuracy checks, field calibrations, transmitter and analyzer calibrations, HART/Fieldbus diagnostics, and verification of calibration records.
• Assure functional safety lifecycle activities for Safety Instrumented Systems (SIS): verification of SIL assessments, SIF testing, proof-test intervals, SIF test coverage, safety validation reports and evidence for regulatory/compliance audits (IEC 61511/61508 awareness).
• Validate DCS/SIS change management and engineering work: ensure proper engineering change control, loop- and cause-and-effect checks, logic validation, FAT/SAT evidence, instrument cross-checking and tagging updates.
• Monitor condition- and performance-monitoring activities (smart diagnostics, valve diagnostic tools, partial discharge for instrument transformers where applicable) and ensure findings are risk-ranked and closed via maintenance plans.
• Govern failure investigation processes for ICC incidents: ensure robust RCAs, identification of root causes, assignment of effective corrective actions and verification of their effectiveness.
• Provide independent challenge on maintenance strategy changes (RCM, FMEA, lifecycle interventions) for ICC assets to ensure technical robustness and appropriate change control.
• Establish and maintain ICC assurance KPIs and dashboards (CMMS data quality, calibration compliance, PM completion, SIF test completion, loop-check pass rates, instrument-related trip frequency, RCA closure) and report to senior leadership and governance forums. Manage contractor and vendor assurance: audit contractor competence and QA/QC processes for instrument technicians, calibration houses and integrators; ensure adherence to SLAs, competence matrices and HSE requirements.
• Champion competency assurance for ICC teams: validate competency matrices, training plans (HART, FOUNDATION fieldbus, DCS, SIL), certification requirements and technical assessment regimes for employees and contractors.
• Support regulatory, insurance and third-party inspections/audits: ensure evidence packs, calibration/test records, SIS proof-test logs and change-management evidence are complete and defensible.
• Lead a team of ICC assurance engineers and specialists, providing direction, coaching and governance to ensure a structured, systematic and compliant approach across the refinery.
• Serve as an independent technical interface with operations, maintenance, projects and OEMs to ensure unbiased assurance and escalation of risks to management

Qualifications and Experience

• Bachelor’s Degree in Electrical, Instrumentation Control, or related engineering discipline; Master’s degree is an advantage.
• Minimum of 25 years’ experience in instrumentation and controls, with at least 10 years in senior leadership roles overseeing operations C maintenance in large refineries or petrochemical complexes.
• Deep knowledge of ICC systems (DCS, SIS, PLCs, analyzers, transmitters, control valves) and standards (IEC 61508, IEC 61511, ISO 17025, ISA/IEC 62443 for cybersecurity).
• Demonstrated experience in CMMS data governance, maintenance strategy development, calibration systems, and functional safety lifecycle management.
• Proven track record in managing contractor competence, technical audits, and assurance programmes in high-hazard industries.
• Strong leadership, communication and stakeholder management skills, with the ability to lead multi-disciplinary teams and influence senior management.
