Senior Materials & Corrosion Engineer

Job Title: Senior Materials & Corrosion Engineer 

Reports To: Inspection Manager

Location: Dangote Petroleum Refinery and Petrochemicals FZE, Lagos 

Job Summary

The Materials & Corrosion Engineer is responsible for safeguarding refinery assets against degradation caused by corrosion, erosion, and material incompatibility. They act as the technical authority for materials selection and corrosion control, ensuring that equipment and piping systems are designed, operated, and maintained to achieve maximum reliability and safety. This role is critical in extending asset life, reducing maintenance costs, and preventing failures that could lead to safety incidents or production losses.

Key Duties and Responsibilities

Materials Selection & Specification

• Recommend appropriate materials for new projects, repairs, and modifications.
• Review design packages to ensure materials meet service conditions (temperature, pressure, chemical exposure).
• Develop and maintain refinery materials standards and specifications.
• Provide crude selection integrity assessments and implications and can veto the crude proposed if this risks plant integrity.

Corrosion Control & Monitoring

• Design and implement corrosion monitoring programs (coupons, probes, ultrasonic thickness surveys).
• Evaluate corrosion data and recommend mitigation strategies.
• Specify and oversee application of protective coatings, linings, and cathodic protection systems.

Failure Analysis & Investigation

• Lead root cause analysis of material failures (fracture, stress corrosion cracking, erosion, hydrogen embrittlement).
• Prepare detailed reports with corrective and preventive recommendations.
• Liaise with OEMs and laboratories for advanced metallurgical testing.

Inspection & Integrity Support

• Work closely with inspection teams to interpret material degradation findings.
• Support RBI engineers with corrosion risk assessments.
•  Validate inspection intervals based on corrosion rates and material performance.

Chemical Treatment & Inhibitors

• Recommend and monitor use of chemical inhibitors in process streams.
• Evaluate effectiveness of treatment programs and adjust dosing strategies.

Governance & Compliance

• Ensure compliance with API, ASTM, ASME, NACE, and refinery-specific standards.
• Participate in Management of Change (MOC) processes for material-related modifications.
• Support audits and regulatory inspections.

Training & Mentorship

• Train inspectors and engineers on corrosion mechanisms and materials awareness.
• Mentor junior engineers in metallurgy and corrosion engineering practices.

Experience Level

• Engineer: 5–8 years in materials/corrosion engineering, preferably in oil & gas.
• Senior Engineer/Technical Authority: 10–15 years, with proven expertise in refinery or petrochemical environments.

Education & Certifications

• Education: BSc/BEng in Metallurgical, Materials, Mechanical, or Chemical Engineering.

Certifications (preferred):

• NACE Corrosion Specialist or CP Level 3 Certification.
• API 571 – Damage Mechanisms in the Refining Industry.
• API 580/581 – Risk-Based Inspection.
• ASME Metallurgy and Materials courses.
• Advanced training in failure analysis and corrosion monitoring techniques.
