Corrosion and Materials Engineer

INEOS Olefins & Polymers USA LLC – Corrosion and Materials Engineer, Grade 37. Salary range $161,100 – $200,365 (commensurate with experience), location TBD (Hybrid).

The Corrosion & Materials Engineer serves as the enterprise technical authority for metallurgy, corrosion control, damage mechanisms, and welding practices across INEOS O&P USA. The role provides expert guidance on material selection, welding procedures, and corrosion mitigation for critical equipment worth over $15B in replacement value. It supports site engineering, inspection, turnaround, and capital projects across three manufacturing sites and the O&P pipeline business.

• Provide authoritative guidance on alloy selection, welding compatibility, and material upgrades for vessels, piping, storage tanks, and critical equipment.
• Review fitness‑for‑service evaluations, repair strategies, and material substitutions for severe or complex integrity challenges.
• Support Management of Change processes for exotic materials or non‑routine material decisions.
• Lead failure analyses and root‑cause investigations involving materials or metallurgical failures.
• Maintain enterprise materials engineering standards and reference documents.

• Lead the enterprise CUI inspection and mitigation strategy across all sites.
• Develop and maintain the CUI inspection program, risk‑based prioritization, and coatings strategy.
• Define standards for insulation systems, protective coatings, and weatherproofing.
• Track program performance and drive continuous improvement.

• Identify, document, and manage active and potential damage mechanisms (e.g., hydrogen attack, sulfidation, chloride stress corrosion cracking).
• Conduct damage mechanism reviews (DMRs) and maintain corrosion control documents (CCDs).
• Collaborate with inspection teams, process engineering, and operations to monitor damage mechanisms.
• Interpret inspection data to identify systemic threats and emerging degradation risks.

• Develop and approve welding procedures and repair practices for all assets.
• Support field execution of critical welds, fabrication methods, and in‑service repairs.
• Ensure compliance with applicable codes (e.g., API, ASME SectionIX).
• Review contractor WPS/PQR documents and align them with enterprise expectations.
• Coach site teams on welding practices, repair planning, and quality expectations.
• Lead resolution of welding‑related issues during turnarounds and capital projects.

• Provide technical support for turnaround planning and execution from a materials, welding, and corrosion perspective.
• Support post‑turnaround reviews and feed findings into DMRs, CCDs, and welding practices.
• Support capital project teams with material selection, fabrication specifications, and quality assurance for new equipment and modifications.
• Influence the materials, welding, and corrosion‑related portion of annual maintenance and inspection spend (~$175MM+).

• Define and maintain technical procedures for weld repair approvals, metallurgical evaluations, and material selection guidance.
• Collaborate with inspectors and engineers to ensure programs meet risk tolerance and design expectations.
• Establish enterprise best practices for documentation, application, and review of materials, welding, and corrosion controls.
• Drive continuous improvement and standardization across O&P USA.

• Provide functional coaching and mentoring to site mechanical engineers, inspection professionals, and reliability personnel.
• Develop competency standards for the materials and corrosion engineering domain.
• Build a network of site‑based engineering and inspection professionals to share technical learnings.

• Ensure alignment with API, NACE/AMPP, and ASME codes.
• Maintain visibility in external forums and represent INEOS interests.
• Stay current on emerging threats, NDE technologies, and industry incidents.
• Bring external learnings into…
