The Senior Engineer I, Mechanical, Projects serves as the owner’s engineer and mechanical project resource for fixed equipment and piping scope within the Refining Business Unit Projects organization for Phillips 66. This role is responsible for providing technical support, helping maintain expectations for quality and completeness, and reviewing key mechanical deliverables developed by EPC contractors, vendors, fabricators, and third-party engineering firms.

This position is a project-focused mechanical engineering role that applies strong technical knowledge and practical industry experience to support development and execution of capital projects. The role helps verify that proposed mechanical designs, specifications, materials selections, fabrication approaches, inspection plans, and execution strategies are technically sound, safe, reliable, constructable, economical, and aligned with Phillips 66 standards, business objectives, and Management of Change requirements.

The successful candidate must have solid working knowledge of fixed equipment and piping engineering and design activities across FEL, detailed design, procurement, fabrication, construction, and closeout, and be able to work effectively with project personnel, project management teams, less experienced engineers, and third-party engineering contractor teams to improve quality and consistency of deliverables. At this level, the engineer is expected to operate with growing independence, take ownership of assigned scopes, lead complex project tasks, and help guide junior engineers.

What You’ll Do

• Support mechanical scope development and execution for capital projects, with responsibility for technical input, scope development, and early risk identification.
• Review mechanical 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 provide technical guidance on pressure vessels, exchangers, tanks, piping systems, solids handling equipment, and related mechanical scope.
• Review EPC, vendor, fabricator, and third-party engineering mechanical deliverables to verify completeness, technical adequacy, constructability, and compliance with Phillips 66 requirements.
• Support quality assurance over mechanical deliverables to verify that fixed equipment and piping designs meet site expectations and project requirements.
• Review equipment layout, piping routing, access, maintainability, operability, and constructability considerations during project development.
• Help assure appropriate design conditions, metallurgy selections, corrosion allowances, welding procedures, inspection requirements, and mechanical integrity considerations are incorporated into project designs.
• Perform or review bolted joint assessments and flange management considerations for critical service applications.
• Review IFA and IFC mechanical design packages to verify technical quality, completeness, constructability, and alignment with project requirements and approved design basis.
• Participate in project milestone reviews including kickoff meetings, design reviews, model reviews, constructability reviews, and issue-for-approval / issue-for-construction package reviews.
• Support mechanical engineering aspects of Management of Change and help ensure changes are technically justified, properly documented, and effectively implemented.
• Provide technical input to contractor and vendor selection, fabrication strategy, inspection planning, and quality hold points for critical equipment.
• Support project teams in identifying mechanical risks, scope gaps, and early engineering needs during FEL to reduce execution risk.
• Coordinate with inspection, corrosion, reliability, process safety, operations, maintenance, procurement, construction, and project management stakeholders to ensure mechanical scope is integrated into the overall project.
• Support field execu
