Infrastructure & Capital Projects – Mechanical Engineer - Power Generation (CCGT), ANS

You’ll perform independent design assurance reviews of mechanical engineering deliverables prepared by the EoR and major equipment suppliers for utility-scale CCGT projects.

· You’ll 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.

· You’ll support our 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.

· You’ll 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 before they affect field execution or commissioning.

· You’ll review Requests for Information (RFIs), technical queries, design deviations, field change notices, and proposed scope changes and provide owner-side recommendations regarding technical acceptability, cost/schedule implications, and required follow-up.

· You’ll review Nonconformance Reports (NCRs), quality observations, and field installation issues; evaluate proposed dispositions and corrective actions; and support development of technically sound mitigation plans in coordination with the EoR, construction team, OEMs, and project leadership.

· You’ll support constructability reviews and field walkdowns to verify that design intent, access, maintainability, equipment clearances, piping routing, lifting/maintenance requirements, and system interfaces are appropriately addressed.

· You’ll support Management of Change (MOC) by evaluating mechanical scope changes, identifying downstream design and construction impacts, and helping ensure affected drawings, specifications, calculations, schedules, costs, and commissioning documents are updated.

· You’ll support system completion, turnover, commissioning, startup, and performance testing by reviewing system boundaries, test packages, punch items, temporary configurations, vendor requirements, and technical issues affecting readiness.

· You’ll collaborate with civil/structural, electrical, I&C, construction, commissioning, project controls, commercial, and operations-readiness teams to resolve multidisciplinary design and field issues.

· You’ll 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.

· You’ll promote safe design and construction practices and identify engineering conditions that could create safety, reliability, operability, maintainability, environmental, or asset-performance risk.

· Onsite at client site: The work location for this role is onsite in St. Louis, Missouri, with our clients and project partners to enable delivery and cultivate strong client relationships.
