Key Responsibilities

Team Leadership

Lead, organize, and supervise the mechanical assurance team, allocating engineers across contractor packages, equipment systems, and project areas to match site progress.

Mentor and provide technical direction to Mechanical Assurance Associates and local site engineers, including onboarding and training as the team scales; review and quality-control their inspection findings and reports before issue.

Coordinate day-to-day activities with the Lead Civil, Lead Electrical, Lead Instrumentation, and Lead Cost Engineer consultants, and report progress, risks, and resourcing needs to the Project Director.

Represent IPMC’s mechanical assurance function in meetings with the Employer’s site management and project team, escalating and resolving conflicts or ambiguities in instructions.

Technical Assurance

Verify mechanical installations—including static and rotating equipment, pressure vessels, tanks, pumps, compressors, piping systems, valves, supports, and associated utilities—against approved drawings, specifications, and, at completion, As-Built records.

Conduct site inspections and technical audits, personally and through supervised staff, to confirm material traceability, welding and NDT records, pressure testing, alignment, installation quality, and compliance with project requirements.

Witness or review critical mechanical tests and milestones, including hydrostatic/pneumatic tests, equipment installation and alignment checks, mechanical completion, pre-commissioning, and relevant performance tests, as a basis for contractor invoice certification.

Validate project progress and provide technical input into contractor interim and final account certification, including evaluation of variation claims relating to the mechanical scope.

Identify technical risks, non-conformities, defects, and quality concerns, and drive timely corrective action and close-out with contractors.

Prepare and review assurance reports, audit findings, punch lists, and monthly progress reports for submission to the Employer’s representative.

Support schedule, materials, equipment delivery, and procurement-compliance reviews within the mechanical discipline as part of IPMC’s wider audit mandate.

Requirements

Bachelor’s degree (minimum) in Mechanical Engineering or a closely related discipline; a Master’s degree is an advantage.

Minimum 12 years of relevant post-qualification experience, including demonstrated time in a lead or supervisory capacity, on industrial, oil & gas, petrochemical, refinery, fertilizer, power, or major infrastructure projects.

Professional registration such as COREN, PE, CEng, or an equivalent international body.

Demonstrated experience leading or supervising multi-person technical teams, including mentoring junior and mid-level engineers.

Strong working knowledge of piping and pressure systems, static and rotating equipment, welding, fabrication, mechanical installation, inspection, testing, and commissioning interfaces.

Familiarity with applicable ASME, API, ASTM, AWS, ISO and related international codes and standards, together with a willingness to work within Nigerian regulatory and site requirements.

Prior international or expatriate assignment experience preferred, ideally within West Africa or a comparable emerging-market industrial environment.

Consulting, Owner’s Engineer, EPC/EPCM, Third-Party Inspection, Project Assurance, or Technical Audit experience is essential for this role.
