• Perform simulations using Aspen HYSYS (preferred) or equivalent tools
• Develop:
• Process Flow Diagrams (PFDs)
• Piping & Instrumentation Diagrams (P&IDs)
• Heat & material balances
• Evaluate system performance, troubleshoot operational issues, and recommend improvements

Design & Drafting

• Develop detailed 2D/3D CAD drawings using SolidWorks (preferred) or AutoCAD:
• Skid layouts and modular equipment packages
• General Arrangement (GA) drawings
• Piping isometrics and spool drawings
• Equipment layouts for field installation
• Translate process requirements into constructible, field-ready designs
• Ensure designs comply with:
• ASME, ANSI, CSA (as applicable)
• Company and client specifications
• Support redlines, as-builts, and revision control

Project Execution & Field Support

• Collaborate with project managers, fabrication teams, and field crews
• Provide site drawing packages for installation and commissioning
• Participate in:

• Field walkdowns and commissioning support
• Resolve field issues by updating drawings and process documentation in real time
• Support procurement with equipment specs and datasheets

Cross-functional Support

• Work closely with mechanical, electrical, and controls teams
• Assist in development of:
• Equipment sizing (vessels, compressors, heaters, valves)
• Instrumentation and control philosophies
• Contribute to continuous improvement of design standards and templates

Safety, Compliance & Standards

• Participate in HAZOP and safety reviews
• Ensure compliance with engineering and design standards
• Support permitting and regulatory documentation

• Bachelor’s degree in Chemical Engineering or Mechanical Engineering

Experience

• 2-8 years in natural gas processing, CNG/LNG or midstream systems
• Experience with natural gas decompression / decanters, compression systems, and/or oilfield / industrial site designs and layouts

Technical Skills

• SolidWorks (preferred) or AutoCAD - strong proficiency required
• Aspen HYSYS (preferred) or similar process simulation tools

• Applicable codes and standards (ASME B31.3, Section VIII, etc.)

Preferred Skills

• Experience with packaged gas systems (CNG trailers, PRUs, VRUs, dehydration skids)
• Exposure to compressor systems (e.g., Ariel, screw compressors, etc.)
• Experience with 3D plant modeling or layout optimization
• Field commissioning or startup experience
• Professional Engineer (P.Eng / PE) designation or eligibility

Soft Skills

• Entrepreneurial mindset and ability to work in a fast-paced environment
• Strong communication across technical and commercial teams
• Hands-on, field-oriented approach
• High attention to detail with execution focus
