What You'll Do
  • Develop the documented design basis, process descriptions, BFDs, PFDs, P&IDs, and material selection diagrams that define each project.

  • Build process simulation models in Aspen HYSYS and develop heat and material balances.

  • Perform hydraulic calculations and produce equipment sizing data sheets for compressors, pumps, heat exchangers, columns, separators, reactors, and more.

  • Design and size safety relief devices that protect personnel, equipment, and the process.

  • Interface directly with clients and provide field support throughout project execution.

  • Deliver work that meets quality standards and applicable codes - on schedule and within budgeted hours.

What You'll Bring (Required)

  • 10+ years of experience in the oil & gas or chemical industries.

  • Hands-on experience designing process equipment (vessels, pumps, exchangers, fired heaters, compressors).

  • Process simulation experience with Aspen HYSYS and hydraulic analysis tools (e.g., AFT Fathom/Arrow, Visual Flare).

  • Strong Microsoft Office skills.

  • Excellent written and verbal communication, with the ability to work in teams and present a positive image to clients.

  • Detail-oriented with a commitment to quality and timely delivery.

Nice to Have (Preferred)
