Interested in joining a winning team? A team whose employees are empowered to make a difference? Company: Olefins and Polymers USA LLC Job title: Corrosion and Materials Engineer Grade: 37 Offer Range: $161,100 - 200,365 (commensurate with experience) Location: TBD - (Hybrid) How the job fits In 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. The O&P USA Business has been and remains a very dominant contributor to INEOS Group financial performance. Although financially strong, the Business has been and remains devoid of effective operational management systems, practices, procedures and competencies, and this set of structural deficiencies, coupled with an ongoing loss of experience and ageing assets in relatively poor condition is a real and very significant threat to the continued success of the Business in the short- through long-term. The Business has operated over the long-term with a poor understanding of and compliance with many INEOS Group, regulatory, industry and performance standards. A significant intervention to address this structural threat to the Business has been defined and actioned by the O&P USA Board and endorsed by INEOS Capital. Central to this intervention is creation and implementation of a corporate Operations Management System (OMS) that will define, at a corporate level, how all elements of engineering, operations and technology will be defined, structured, standardised and managed going forward. Critical to the successful delivery of the OMS is creation of a Corporate Engineering & Technology Organization, and population of that organization with senior, competent and experienced discipline leaders, with the technical capability and gravitas to design, communicate and manage their engineering / operational discipline to significantly improved and consistent standards across the entire O&P USA Business. The E&T organization will hold all discipline engineering Technical Authorities in the Business, who will set corporate standards, practices, procedures and competency requirements across all operating locations. This is a purposeful and complete reversal in structure to previous / current where personnel at the operating Sites had an assumed authority for all technical discipline policies, practices, structures and standards at their individual location; an approach that has not worked and is the root cause of the many performance issues encountered today. The post holder must have deep understanding of their engineering discipline and have successful experience of setting policy and driving compliance to required standards across a large and diverse manufacturing organization. The post holder must be a proven and resilient agent for change. 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.
