Corrosion and Materials Engineer 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 the deep technical expertise that underpins sound materials and corrosion decisions across pressure vessels, piping, storage tanks, and critical equipment representing $15B+ in enterprise replacement value assets. Technical guidance provided by this role directly protects long-term asset integrity, weld and material reliability, and the company's license to operate. Within the discipline of materials, welding, and corrosion engineering, the Corrosion & Materials Engineer defines enterprise standards for material selection, welding procedures, damage mechanism reviews, and corrosion control. Site engineering and inspection teams operate within the technical framework established by this role and rely on it as the senior technical resource for severe or complex problems involving metallurgy, weld repair, or corrosion threats. While the position has no direct line authority over site personnel, its functional leadership and structured technical guidance establish how materials and corrosion decisions are made across all O&P USA sites. The role spans three major manufacturing sites and the O&P USA pipeline business, leading enterprise programs for damage mechanism reviews, corrosion control documents, welding procedures, and CUI inspection and mitigation. Through technical leadership in these specialized programs, the role shapes the materials, welding, and corrosion-related portion of $175MM+ in annual maintenance and inspection spend and informs the technical foundations of major capital and turnaround decisions. The Corrosion & Materials Engineer is recognized as a technical authority within INEOS and is expected to actively participate in relevant industry forums and committees, including API committees and NACE/AMPP corrosion groups, ensuring that O&P remains aligned with emerging codes, NDE technologies, and best practices in materials science, corrosion control, and welding engineering. Materials, welding, and corrosion engineering decisions made by this role directly support long-term equipment reliability, the company's regulatory compliance posture, and the avoidance of asset failures with potential for major safety, environmental, and financial impact. This person serves as the enterprise senior technical resource for all materials, welding, and corrosion matters affecting fixed equipment integrity across the O&P USA Business. Skills and Knowledge Requirements Level of education & Experience in general Bachelor's degree in Materials Science, Welding Engineering, Metallurgical Engineering, or Mechanical Engineering; advanced degree preferred.15-20 years of experience in welding, materials, or corrosion engineering in refining, petrochemical, or heavy industrial environments. Certified or highly proficient with API 510, 570, 579 (FFS), 582, and ASME Section IX, with the ability to apply them to varied plant environments. Experience developing or qualifying welding procedures and reviewing contractor WPS/PQR documents. Strong understanding of corrosion mechanisms in hydrocarbon and polymer processing, including CUI, high-temperature sulfidation, and chloride stress corrosion cracking. Demonstrated experience with damage mechanism reviews and corrosion control document development. Active participation in external industry forums (e.g., API committees, NACE/AMPP) preferred. Technical skills Recognized company authority on metallurgy, materials selection, and fabrication methods for pressure equipment and piping in hydrocarbon and polymer service Extensive knowledge of materials and welding codes, including API 510, 570, 571, 579, 580, 581, 582, 653, and ASME Section IXStrong knowledge of degradation mechanisms, corrosion processes, and their interaction with materials of construction, process conditions, and operational history Skilled in developing welding procedures, evaluating weld quality, and supporting field execution of critical repairs Experienced in fitness-for-service assessments, failure analysis, and root cause investigations involving materials or corrosion failures Ability to interpret inspection data and translate findings into actionable corrosion control and materials engineering strategies Knowledge of coatings, insulation systems, and cathodic protection as they relate to corrosion mitigation Strong working knowledge of OSHA 1910.119 (PSM) as it relates to Mechanical Integrity programs, with experience in chemical, refining, or petrochemical operations Actively engages with external industry networks and applies new technologies or practices to improve materials and corrosion performance and reduce risk Behavioral skills Effective communicator, capable of providing field support, authoring technical documents, and coaching stakeholders at all levels Builds credibility through technical depth, practical problem-solving, and consistent follow-through Builds strong, trust-based relationships with site leaders, engineers, inspectors, and welding personnel Persistent and thorough in resolving complex materials and corrosion challenges Steers sites toward standard materials, welding, and corrosion practices through coaching and influence, while recognizing local constraints only where truly necessary Prioritizes and organizes complex workloads with competing stakeholder demands Collaborates effectively across functions, working with inspection, maintenance, operations, process engineering, and project teams Takes a long-term stewardship view of asset integrity, balancing near-term repair needs with lifecycle risk Sees patterns and systemic risks across sites, not just individual materials or corrosion findings Demonstrates sound judgment in high-stakes engineering decisions affecting equipment safety and reliability Operates with a long-term view, connecting daily materials and corrosion work to lifecycle integrity outcomes Brings curiosity and external awareness, staying current with evolving codes, industry practices, and emerging corrosion threats Earns trust by delivering value, not just enforcing compliance Our culture is one of honesty and integrity with an emphasis on safety, health and environmental performance. On our team, people are acknowledged for embracing new practices that help create real value for customers.
