The Corrosion & Materials Engineer is the recognized enterprise subject matter expert for metallurgy, corrosion control, damage mechanisms, and welding practices across INEOS O&P USA. Reporting to the Equipment Integrity Manager & Technical Authority, this role provides deep technical expertise that underpins sound materials and corrosion decisions across pressure vessels, piping, storage tanks, and critical equipment representing $15 B+ in enterprise replacement value assets.

Technical guidance protects long‑term asset integrity, weld and material reliability, and the company’s license to operate. The engineer defines enterprise standards for material selection, welding procedures, damage‑mechanism reviews, and corrosion control, and serves as the senior technical resource for severe or complex problems involving metallurgy, weld repair, or corrosion threats.

• Serve as the enterprise senior technical resource for materials of construction for pressure vessels, piping, storage tanks, and critical equipment across O&P USA, providing authoritative guidance on alloy selection, welding compatibility, and material upgrades.
• Provide authoritative input on fitness‑for‑service evaluations, repair strategies, and material substitutions for severe or complex integrity challenges that exceed routine site capability.
• Support site projects and Management of Change processes requiring evaluation of exotic materials, elevated service requirements, or non‑routine material decisions.
• Lead and support failure analyses and root‑cause investigations involving materials or metallurgical failures, contributing technical expertise on failure mechanisms, contributing factors, and systemic corrective actions.
• Maintain enterprise materials engineering standards and reference documents that guide consistent application across all O&P USA sites.

• Lead the enterprise CUI (Corrosion Under Insulation) inspection and mitigation strategy across all O&P USA sites, covering both piping and fixed equipment.
• Develop and maintain the enterprise CUI inspection program, including risk‑based inspection prioritization, sequencing, and coatings strategy.
• Define enterprise standards for insulation systems, protective coatings, and weatherproofing as they relate to CUI prevention, inspection, and mitigation.
• Track CUI program performance across sites and drive continuous improvement in inspection coverage, mitigation effectiveness, and risk reduction year over year.

• Lead the identification, documentation, and management of active and potential damage mechanisms across all O&P USA assets.
• Conduct and maintain damage‑mechanism reviews (DMRs) for process units and critical equipment.
• Develop and maintain enterprise corrosion control documents (CCDs) that define expected degradation, inspection requirements, and mitigation strategies.
• Collaborate with the Chief Inspector and site inspection teams to ensure damage mechanisms are properly identified, monitored, and managed through appropriate inspection plans.
• Review and interpret inspection data to identify systemic threats, emerging degradation risks, and trends requiring enterprise‑level attention.

• Develop and approve welding procedures and repair practices used across all INEOS O&P USA assets, ensuring code compliance and field executability.
• Support field execution of critical welds, fabrication methods, and in‑service repairs.
• Ensure welding procedures comply with applicable codes and standards, including API 582, ASME Section IX, and RAGAGEP.
• Review and qualify contractor WPS and PQR and ensure alignment with enterprise expectations.
• Coach site engineers, maintenance leads, and welding contractors on proper welding practices and quality expectations.
• Lead resolution of welding‑related issues during turnarounds and capital projects.
