Job description

We are seeking an experienced Mechanical Auxiliaries Engineer specializing in heavy-duty industrial gas turbines. In this role, you will be responsible for the specification, integration,and life-cycle management of fluid, pneumatic, and mechanical support systems essential for the reliable operation of large-scale turbomachinery packages. You will collaborate cross-functionally with structural, electrical, and controls teams, manage global vendors, and ensure seamless system execution from initial design through commissioning.

Essential Duties and Responsibilities

The essential functions of the job include, but are not limited to, the following:

• System Design & Engineering: Develop process flow diagrams (PFDs), piping and instrumentation diagrams (P&IDs;), fluid consumption schedules, and component sizing calculations for utility and auxiliary subsystems.
• 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.
• Enclosures: 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.
• 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%.
