8+ years of mechanical engineering experience supporting large capital projects in power generation or process industries such as oil & gas, LNG, refining, chemicals, petrochemicals, or similar facilities
Demonstrated experience reviewing mechanical engineering designs for large, complex industrial facilities through engineering, procurement, construction, and/or commissioning phases
Strong working knowledge of mechanical equipment, piping systems, pressure vessels, heat exchangers, pumps, compressors, valves, piping materials, and related balance-of-plant systems
Working knowledge of applicable engineering codes and standards such as ASME, API, NFPA, ANSI, and other standards relevant to utility-scale power generation
Ability to read and critically evaluate P&IDs, equipment arrangements, piping drawings, vendor drawings, technical specifications, calculations, and engineering change documentation
Demonstrated ability to evaluate technical problems, develop practical recommendations, and communicate effectively with EoR engineers, contractors, OEMs, construction personnel, commissioning teams, and client stakeholders
Ability to perform field walkdowns/observations on foot across active construction areas and moderate to rough terrain and to comply with project PPE and site safety requirements

Nice To Haves

Direct engineering, design assurance, construction, or commissioning experience on utility-scale combined cycle gas turbine (CCGT) or simple-cycle gas generation projects
Experience working in an Owner’s Engineer, Owner’s Representative, EPCM, or independent design assurance role
Experience reviewing Engineer of Record (EoR) deliverables and managing technical interfaces across OEMs, EPC contractors, construction contractors, and owner teams
Experience with projects executed under EPC, EPCM, multi-prime, or owner-managed contracting models
Experience supporting constructability reviews, system turnover, commissioning, startup, and operational readiness
Professional Engineer (PE) license or Engineer-in-Training (EIT) certification, as applicable
Familiarity with digital engineering/document management and project delivery platforms such as Bluebeam, Autodesk/AutoCAD, Navisworks, BIM/3D model review tools, Procore, or equivalent

Responsibilities

Perform independent design assurance reviews of mechanical engineering deliverables prepared by the EoR and major equipment suppliers for utility-scale CCGT projects.
Review mechanical drawings, P&IDs, equipment specifications, data sheets, calculations, equipment layouts, piping designs, line lists, valve specifications, vendor drawings, technical bid evaluations, and other design deliverables for technical completeness, consistency, constructability, operability, and compliance with project requirements.
Support clients by providing technical oversight of major CCGT mechanical systems and interfaces, including gas turbines, HRSGs, steam turbine systems, condensate and feedwater systems, condenser and circulating water systems, cooling systems, fuel gas systems, auxiliary steam, compressed air, water treatment, chemical feed, fire protection, and other balance-of-plant systems.
Evaluate design interfaces and battery limits between OEM equipment, EoR-designed systems, balance-of-plant packages, and construction work packages to identify gaps, conflicts, and integration risks.
Review Requests for Information (RFIs), technical queries, design deviations, field change notices, and proposed scope changes and provide owner-side recommendations.
Review Nonconformance Reports (NCRs), quality observations, and field installation issues; evaluate proposed dispositions and corrective actions; and support development of technically sound mitigation plans.
Support constructability reviews and field walkdowns to verify design intent, access, maintainability, equipment clearances, piping routing, lifting/maintenance requirements, and system interfaces.
Support Management of Change (MOC) by evaluating mechanical scope changes, identifying downstream design and construction impacts, and ensuring affected documents are updated.
Support system completion, turnover, commissioning, startup, and performance testing by reviewing system boundaries, test packages, punch items, temporary configurations, vendor requirements, and technical issues.
Collaborate with civil/structural, electrical, I&C, construction, commissioning, project controls, commercial, and operations-readiness teams to resolve multidisciplinary design and field issues.
Document design assurance findings, maintain technical issue/action logs, support risk identification and mitigation, and provide clear technical recommendations to Project Management and client leadership.
Promote safe design and construction practices and identify engineering conditions that could create safety, reliability, operability, maintainability, environmental, or asset-performance risk.
