Senior Engineer III, Mechanical, Projects

This role serves as a senior technical authority and owner’s engineer for fixed equipment and piping scope within the Projects organization for Refining. It provides advanced technical assurance, strategic guidance, and business perspective across multiple projects, complex scopes, and key project decisions involving refinery fixed equipment, piping, materials, fabrication, inspection, and construction. The position applies deep technical knowledge and broad practical experience to ensure mechanical designs, specifications, vendor deliverables, fabrication approaches, and field execution plans are technically sound, safe, reliable, constructable, cost-effective, and aligned with Phillips 66 standards, business objectives, and Process Safety Management / Management of Change requirements.

Responsibilities

• Serve as the owner’s engineer and senior technical resource for fixed equipment and piping scope on capital projects, with responsibility for technical assurance, quality expectations, and early risk identification.
• Provide mechanical technical leadership across multiple projects, complex scopes, or projects with significant technical, reliability, operability, cost, or schedule risk.
• Review project scope, design basis, process conditions, design conditions, and execution strategies to confirm alignment with project objectives, site requirements, company standards, and applicable codes.
• Review and approve key EPC, vendor, and fabricator mechanical deliverables to verify technical adequacy, constructability, completeness, and fitness for service.
• Establish and reinforce expectations for fixed equipment and piping quality across FEL, detailed design, procurement, fabrication, construction, pre-commissioning, and closeout.
• Lead resolution of complex or novel mechanical issues related to equipment design, metallurgy, corrosion, refractory, insulation, bolted joints, welding, inspection, repairs, piping flexibility, and field installation.
• Review and consult on equipment layout, piping routing, plot plan impacts, access, maintainability, operability, and constructability.
• Assure appropriate design conditions, corrosion allowances, metallurgy selections, welding procedures, inspection requirements, and mechanical integrity considerations are incorporated into project designs.
• Perform or guide bolted joint assessments and review flange management strategies for critical service.
• Review pressure vessel, exchanger, tank, piping, solids handling, and related mechanical packages for technical quality and alignment with project requirements.
• Provide technical input to contractor and vendor selection, fabrication strategy, inspection planning, shop surveillance, and quality hold points for critical equipment.
• Participate in design reviews, model reviews, constructability reviews, HAZOP / PHA interfaces, and issue-for-approval / issue-for-construction package reviews.
• Coordinate mechanical engineering aspects of Management of Change and help ensure changes are technically justified, appropriately documented, and effectively implemented.
• Advise project teams on key mechanical risks, scope gaps, execution tradeoffs, and lessons learned so informed business decisions can be made early.
• Support development, improvement, and standardization of mechanical engineering work processes, refinery engineering practices, specifications, guidelines, and lessons learned.
• Coach and mentor project engineers, less experienced mechanical engineers, and EPC personnel on effective mechanical project execution.
• Influence decisions across disciplines and organizations without direct authority and align stakeholders around practical, value-adding solutions.
• Represent the mechanical discipline in broader business, site, corporate, or external technical forums as needed.
• Ensure project scope and cost are controlled and that change is managed appropriately.
• Establish priorities, deliverables, and deadlines aligned with capital project strategies and business objectives.
• Manage competing priorities and multiple assignments simultaneously while maintaining a long-term view of business value and technical quality.
• Manage time and commitments and deliver clear, practical, and technically sound recommendations.
