Senior Process Engineer

At Nexus Engineering Group, our Process Engineers turn client requirements into safe, buildable process designs — from first calculation to field startup. As a Senior Process Engineer, you’ll own the basic process design of unit operations and the deliverables that drive projects forward, working shoulder-to-shoulder with project teams, vendors, and clients to get it right.

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.

-

Bachelor of Science in Chemical Engineering from an ABET-accredited program.

-

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).

-

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.
