  • Working closely with mechanical engineers, manufacturing teams and customers.
  • Reviewing technical specifications, process data and heat exchanger performance requirements.
  • Mentoring engineers and supporting technical improvements across the business.

At Principal level, you'll also act as a technical authority, taking responsibility for design approvals and the development of thermal engineering standards.

Requirements

  • A Mechanical or Chemical Engineering degree.
  • Typically 6+ years' experience in heat exchanger thermal design.
  • Strong working knowledge of Aspen EDR or HTRI.
  • Experience designing and rating shell-and-tube heat exchangers.
