SCOPE:

The Principal Mechanical Engineer, Genset, serves as the U.S. technical lead for designing, integrating, and executing gas engine-based power generation systems that support data center and distributed energy applications. This role provides technical leadership throughout the project lifecycle, from concept development through commissioning, ensuring compliance with applicable codes, standards, customer requirements, and project objectives. The position collaborates with global engineering teams, suppliers, customers, and contractors to drive technical alignment, manage project risks, and support successful project delivery.

JOB RESPONSIBILITIES:

Lead Mechanical Engineering for Gas Engine Sets

• Lead mechanical engineering activities for gas engine generator systems from requirements definition through commissioning.
• Define system architecture, design requirements, and technical specifications.
• Review and approve engineering deliverables, including GA drawings, fabrication drawings, 3D models, calculations, and supplier documentation.
• Lead technical planning and execution to support project schedules, cost targets, and deliverables.
• Coordinate suppliers, customers, contractors, and cross-functional teams to ensure technical alignment and successful project execution.
• Identify technical risks, develop mitigation plans, and support issue resolution throughout the project lifecycle.
• Support testing, commissioning, troubleshooting, root cause analysis (RCA), and continuous product improvement.

Mechanical System Integration and Performance Leadership

• Define and validate performance requirements for cooling, ventilation, exhaust, fuel, acoustics, vibration, and maintainability.
• Lead packaging, layout optimization, and site integration activities to satisfy customer requirements, operational objectives, and installation constraints.
• Evaluate system performance through design reviews, simulations, testing, commissioning, and field operational feedback.
• Drive reliability, maintainability, and continuous improvement initiatives throughout the product lifecycle.

Compliance and Certification Leadership

• Ensure designs comply with applicable codes, standards, and certification requirements.
• Translate applicable mechanical codes and standards (EPA, NFPA, UL2200, IBC, IMC, IFC, and local AHJ requirements) into engineering specifications, design requirements, and validation plans.
• Develop compliance documentation and support design reviews, testing, and validation activities.
• Support certification, permitting, and compliance activities with EPA, NRTLs, AHJs, customers, and regulatory authorities.
• This list of responsibilities is not all-inclusive, and an employee may be required to perform other relevant duties as assigned

MINIMUM REQUIRED QUALIFICATIONS:

• Education: Bachelor's degree in mechanical engineering or a related technical field
• Experience: Minimum of twelve (12) years of mechanical engineering experience in industrial power generation, rotating equipment, or energy systems.
• Minimum of six (6) years of experience with generator sets, gas engines, diesel engines, or packaged power generation systems.
• Demonstrated experience with gas engine integration, cooling systems, exhaust systems, fuel systems, and genset packaging.
• Experience reviewing and approving General Arrangement (GA) drawings, fabrication drawings, and 3D models.
• Strong knowledge of structural integration, vibration isolation, ventilation, thermal management, and mechanical system design.
• Experience managing suppliers, engineering contractors, and project technical interfaces.

PREFERRED QUALIFICATIONS:

• Experience supporting data center backup power generation or distributed energy projects.
• Experience with acoustic analysis, vibration analysis, airflow modeling, or thermal simulations.
• Experience with generator enclosure design, structural packaging, ventilation, and thermal management.
• Experience supporting FAT, commissioning, field startup, troubleshooting, and Root Cause Analysis.
• Experience with CAD and 3D modeling software such as SolidWorks, Inventor, AutoCAD, or similar tools.
• Professional Engineer (PE) license.

WORKING CONDITIONS:

• Travel: 20% (as required by project/customer needs).
• Physical Requirements: Regularly required to sit for extended periods; stand, walk, talk, and hear. Frequently lift and/or move up to 10 pounds and occasionally lift and/or move up to 25 pounds.
• Standard Monday through Friday work week. Weekend or after-hours work may be required based on project schedules and commissioning activities.
