• Specification Procurement

  Author comprehensive Request for Quotations (RFQs) and technical specifications for major balance-of-plant (BOP) and auxiliary equipment. Evaluate technical bids from global vendors.

  
  

• Vendor Management

  Oversee auxiliary skid suppliers to ensure compliance with engineering standards, project milestones, quality requirements, and cost targets.

  
  

• Design Reviews

  Lead and participate in design reviews, focusing on equipment performance, layout, maintenance accessibility, and structural skids interface.

  
  

• Cross-Functional Integration

  Interface directly with EPC (Engineering, Procurement, and Construction) partners and internal electrical/controls engineering teams to ensure accurate physical and functional boundaries.

  
  

• Testing & Field Support

  Support Factory Acceptance Testing (FAT) at vendor facilities, and provide remote or on-site technical resolution during package commissioning, field installation, and troubleshooting.

  
  

• Core Technical Domain & Subsystems The ideal candidate will have direct design or integration ownership over the following subsystems:
• Seal Oil / Lube Oil Systems

  Lube and Lift oil skid, conditioning systems, and seal oil for hydrogen cooled generator.

  
  

• Fuel Delivery Systems

  Gas fuel regulating skids and fuel filtration.

  
  

• Air Management

  Inlet air filtration systems (evaporative coolers, pulse filters) and turbine enclosure ventilation/cooling.

  
  

• Water Wash

  Water Wash pumps, nozzles and piping

  
  

• Fire Protection: Fire detection and suppression systems (CO2, water mist), fire protection control panels, and associated distribution piping and nozzles.
• E nclosures

  Gas Turbine, Load Compartment, and Exhaust sound barrier

  
  

• Cooling Water

  Glycol-Water specification and cooling requirements

  
  

• Instrument Air

  Air compressors, dryers, filters, receivers, and distribution piping for pneumatic valves, actuators, and instrumentation

  
  

• Exhaust Systems

  Exhaust ducting, expansion joints, silencers, exhaust stack, emission reduction equipment, and thermal insulation.

  
  

• Ventilation & Heating Systems

  Enclosure ventilation fans, air filtration, dampers, ductwork, space heaters, and temperature control systems.

  
  

Minimum Requirements

• Education

  Bachelor's degree in Mechanical Engineering, Aerospace Engineering, or an equivalent technical field.

  
  

• Experience

  Minimum of 5+ years of relevant experience in turbomachinery, rotating equipment packages, or industrial process plant design.

  
  

• Standards Expertise

  Strong working knowledge of API standards (specifically API 614 for lubrication systems, API 617/616), ASME B31.1 / B31.3 piping codes, and standard ASME Section VIII pressure vessel design rules.

  
  

• Software Proficiency

  Authoring and/or reviewing CAD drawings and P&IDs, experience with thermodynamic/fluid modeling tools is a plus.

  
  

• Skills

  Analytical troubleshooting, attention to documentation detail, supplier management, and strong communication skills.

  
  

• Must be able to travel up to 25%.
