About The Position

The Principal Mechanical Engineer, Genset serves as the U.S. technical lead for designing, integrating, and executing gas engine-based power generation systems for data center and distributed energy applications. The role provides technical leadership throughout the project lifecycle, from concept development through commissioning, ensuring compliance with applicable codes, standards, customer requirements, and project objectives. It collaborates with global engineering teams, suppliers, customers, and contractors to align technical work, manage project risks, and support successful delivery. The position leads mechanical engineering for gas engine generator systems, including system architecture, design requirements, technical specifications, and review and approval of engineering deliverables. It leads system integration and performance work across cooling, ventilation, exhaust, fuel, acoustics, vibration, packaging, layout, and maintainability. It also leads compliance and certification efforts, translating applicable codes and standards into engineering requirements and supporting documentation, reviews, testing, permitting, and validation. The role requires travel of 20% as needed by project or customer needs. The standard work week is Monday through Friday; weekend or after-hours work may be required based on project schedules and commissioning activities. Physical requirements include extended periods of sitting; standing, walking, talking, and hearing; frequently lifting or moving up to 10 pounds; and occasionally lifting or moving up to 25 pounds.

Requirements

  • Bachelor’s degree in mechanical engineering or a related technical field.
  • At least 12 years of mechanical engineering experience in industrial power generation, rotating equipment, or energy systems.
  • At least 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.

Nice To Haves

  • 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.

Responsibilities

  • 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, and continuous product improvement.
  • Define and validate performance requirements for cooling, ventilation, exhaust, fuel, acoustics, vibration, and maintainability.
  • Lead packaging, layout optimization, and site integration activities to meet 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.
  • Ensure designs comply with applicable codes, standards, and certification requirements.
  • Translate applicable mechanical codes and standards—including 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.
  • Perform other relevant duties as assigned.
