  • 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
• 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

Cross-functional Support

• Work closely with mechanical, electrical, and controls teams
• 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

Qualifications

Education

• Bachelor’s degree in Chemical Engineering or Mechanical Engineering

Experience
