[Hiring] Natural Gas Compression Subject Matter Expert @AECOM

Role Description

AECOM is seeking a Natural Gas Compression Subject Matter Expert (SME) to join our multi-disciplinary design team in support of major gas transmission projects. This role is a remote position, allowing the selected candidate to work a remote schedule.

The selected individual will serve as the firm’s lead technical authority for compression stations, establishing:

• Overall compression philosophy
• Equipment selection criteria (reciprocating vs. centrifugal compressors)
• Driver selection (gas turbines, electric motors)
• Station layout standardization

This position serves as the primary technical authority for gas compression process and equipment selection, providing:

• Top-level engineering direction
• Technical governance
• Oversight across all compression station designs

Key responsibilities include:

• Define over-pressure protection systems, relief valves, and blowdown system strategies in accordance with API, ASME, and CFR.
• Lead and review complex thermodynamic and gas hydraulic calculations, including:
• Multi-stage compressor sizing
• Intercooling/aftercooling design
• Fuel gas system conditioning
• Transient gas flow behavior
• Direct and review specialized dynamic analysis, including:
• Pulsation/acoustic studies (API 618/API 688)
• Torsional vibration analysis
• Pipe stress/surge analysis (ASME B31.8 / AFT Impulse)
• Author and review critical technical specifications and data sheet packages for major rotating equipment.
• Lead high-level Technical Bid Evaluations (TBEs), vendor package integration, factory acceptance testing (FAT) witness points, and technical alignment across major OEM suppliers.
• Drive standardization to streamline engineering, procurement, and constructability.
• Review critical project deliverables, including:
• Process Flow Diagrams (PFDs)
• Piping & Instrumentation Diagrams (P&IDs)
• Compressor building layouts
• ESD (Emergency Shut-Down) system logic
• Hazard mitigation plans
• Support proposal development with technical write-ups, compression strategy narratives, engineering hour estimations, and client presentation support.
• Interface directly with client leadership, regulatory bodies, and operations teams as AECOM's key technical representative for gas compression strategy.
• Conduct high-level technical reviews and check engineering calculations produced by design teams.
• Mentor senior and mid-level mechanical engineers on pipeline dynamics, rotating equipment specifications, and industry best practices.

Qualifications

• BA/BS in Mechanical Engineering or related field + 8 years of related experience or demonstrated equivalency of experience and/or education.
• 8 years of experience in mechanical design engineering within the natural gas, pipeline midstream, or energy infrastructure sectors.
• Professional Engineer (PE) License.
• Proven track record as a Lead Engineer or SME on large-scale natural gas compression station projects (greenfield or major brownfield expansions).
• Understanding of design, industrial process, and energy projects.
• Experience in industrial and/or energy-related fields.

Requirements

• Masters Degree in Mechanical Engineering or related field (preferred).
• Extensive experience with major compressor technologies (large reciprocating compressor packages and/or gas-turbine-driven centrifugal units) and associated auxiliary systems.
• Expert-level knowledge of relevant standards and codes (e.g., ASME B31.8, API 618, API 617).
• Hands-on expertise or oversight capabilities with gas hydraulic and compressor performance tools.
• Strong working understanding of environmental, air quality, and acoustic compliance constraints related to compressor station noise and emissions control.

Benefits

• Medical, dental, and vision insurance
• Life, AD&D, and disability benefits
• Paid time off and leaves of absence
• Voluntary benefits and perks
• Flexible work options
• Well-being resources and employee assistance program
• Business travel insurance
• Service recognition awards
• Retirement savings plan
• Employee stock purchase plan
