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

  • Experience with PSV sizing and safety relief device design, with a strong understanding of underlying process fundamentals and relief system behavior.  

  • 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

  • PPE (hard hat, safety glasses, hi-vis vest, steel-toed boots) provided and required on site. 

$110,000 - $160,000 a year
Compensation for all candidates is determined based on experience, qualifications, skill set, certifications, work location, and market conditions.
