Projects Phillips 66 & YOU - Together we can fuel the future The Senior Engineer III, Mechanical, Projects role serves as a senior technical authority and owner's engineer for fixed equipment and piping scope within the Projects organization for Refining. This role 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.

This position applies deep technical knowledge and broad practical experience to ensure that 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. This position is expected to operate with independence, influence, and organizational impact;

resolve unusually difficult or high-consequence technical issues; coach and mentor engineers and project teams; and help improve mechanical engineering practices, standards, and execution quality across projects.

What You'll Do Serving 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. Providing mechanical technical leadership across multiple projects, complex scopes, or projects with significant technical, reliability, operability, cost, or schedule risk. Reviewing project scope, design basis, process conditions, design conditions, and execution strategies to confirm alignment with project objectives, site requirements, company standards, and applicable codes.

Reviewing and approving key EPC, vendor, and fabricator mechanical deliverables to verify technical adequacy, constructability, completeness, and fitness for service. Establishing and reinforcing expectations for fixed equipment and piping quality across FEL, detailed design, procurement, fabrication, construction, pre-commissioning, and closeout. Leading 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.

Reviewing and consulting on equipment layout, piping routing, plot plan impacts, access, maintainability, operability, and constructability. Assuring appropriate design conditions, corrosion allowances, metallurgy selections, welding procedures, inspection requirements, and mechanical integrity considerations are incorporated into project designs. Performing or guiding bolted joint assessments and reviewing flange management strategies for critical service. Reviewing pressure vessel, exchanger, tank, piping, solids handling, and related mechanical packages for technical quality and alignment with project requirements.

Providing technical input to contractor and vendor selection, fabrication strategy, inspection planning, shop surveillance, and quality hold points for critical equipment. Participating in design reviews, model reviews, constructability reviews, HAZOP / PHA interfaces, and issue-for-approval / issue-for-construction package reviews. Coordinating mechanical engineering aspects of Management of Change and helping ensure changes are technically justified, appropriately documented, and effectively implemented. Advising project teams on key mechanical risks, scope gaps, execution tradeoffs, and lessons learned so informed business decisions can be made early.

Supporting development, improvement, and standardization of mechanical engineering work processes, refinery engineering practices, specifications, guidelines, and lessons learned.
