The Staff MEP Engineer serves as the senior mechanical, electrical, plumbing technical authority for the power generation and microgrid portfolio and provides technical leadership to all mechanical engineers on the team. This role owns mechanical system architecture, engineering governance, and complex technical decision-making for engine-based power plants, spanning fuel gas systems, heat rejection, lubrication, starting air, exhaust and emissions interfaces, and building mechanical systems.

The Staff MEP Engineer defines scalable, repeatable mechanical solutions across a multi-project portfolio, establishes and enforces engineering standards, and resolves high-risk technical challenges affecting plant performance, reliability, and schedule.

• Lead and direct the mechanical,engineering,plumbing engineering team: assign and review work, set technical priorities, establish checking discipline, and develop engineers across concurrent projects.
• Serve as Subject Matter Expert for mechanical balance of plant on reciprocating engine power generation, including fuel gas systems, cooling water circuits, lube oil, compressed and starting air, exhaust, and emissions equipment interfaces.
• Define and approve mechanical system architectures, equipment arrangements, and plot plans for modular, scalable power plants.
• Lead and approve P&IDs, piping and equipment specifications, line and equipment lists, and issue-for-construction mechanical packages.
• Author, approve, and maintain corporate mechanical standards, specifications, and design guidelines, driving standardization across the portfolio.
• Direct mechanical system studies, including fuel gas hydraulics and pressure regulation, cooling hydraulics and heat rejection, exhaust back pressure, pipe stress, relief and vent design, ventilation and combustion air, and utility consumption.
• Own building mechanical scope for engine halls and electrical buildings, including ventilation, HVAC, and fire protection interfaces.
• Establish the mechanical basis of design for each project, including site ambient and altitude effects on equipment rating and performance.
• Provide final technical authority on vendor mechanical packages (engine auxiliaries, balance-of-plant skids, radiators, emissions systems), including specification, bid evaluation, submittal review, and interface resolution.
• Coordinate mechanical interfaces with the engine OEM, EPC contractor, owner's engineer, gas supplier, and authorities having jurisdiction.
• Support construction and commissioning: respond to RFIs, disposition field changes, witness critical mechanical testing, and support first fuel gas introduction and engine startup.
• Lead high-risk troubleshooting and mechanical failure investigations from root cause through corrective action and standards feedback.
• Participate in executive-level safety and technical risk reviews, and support long-range technical planning and capital strategy.
• Other duties as assigned.

• Bachelor of Science in Mechanical Engineering from an accredited program
• Licensed Professional Engineer
• 12 or more years of progressive mechanical engineering experience, including substantial experience with mechanical balance of plant for engine- or turbine-based power generation or comparable heavy industrial facilities
• Demonstrated design experience with fuel gas systems (pressure regulation, conditioning, valve trains) and closed-loop cooling and heat rejection systems
• Expert working knowledge of ASME codes (including B31.1/B31.3 piping), NFPA standards applicable to engine installations and fuel gas, and applicable mechanical and building codes
• Proven ability to take mechanical designs from basis of design through installable, code-compliant construction packages and support them in the field
• Experience leading, checking, and developing other engineers
• Strong vendor, contractor, and cross-discipline coordination skills, with effective verbal and written…
