  • 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

• Collaborate with project managers, fabrication teams, and field crews
• Provide site drawing packages for installation and commissioning
• Participate in:
  • Equipment FAT/SAT
  • Field walkdowns and commissioning support
• Resolve field issues by updating drawings and process documentation in real time
• Support procurement with equipment specs and datasheets

• Work closely with mechanical, electrical, and controls teams
