Sr. Process Systems Engineer

Nucor•Bethlehem, PA

About The Position

Universal Industrial Gases, LLC, a wholly owned subsidiary of Nucor, is seeking a Senior Process Systems Engineer to serve as the technical owner and primary engineering authority for Process & Instrumentation Diagrams (P&IDs) on cryogenic air separation projects. The engineer will maintain P&ID technical integrity and ensure drawings translate process design intent into safe, operable, maintainable, and constructible systems throughout the project lifecycle, from concept through detailed engineering, construction, commissioning, and final as-built documentation. Direct experience with cryogenic Air Separation Units (ASUs) producing oxygen, nitrogen, and argon is strongly preferred. The role leads P&ID coordination across process, mechanical, piping, instrumentation and controls, safety, suppliers, construction, commissioning, and operations. It also supports equipment specification, technical bid evaluation, vendor reviews, construction, commissioning, startup, performance testing, and troubleshooting. The position is based in Bethlehem, Pennsylvania. Safety is emphasized as the most important part of work at Nucor, and teammates are expected to uphold safety policies, procedures, practices, and housekeeping standards.

Requirements

Bachelor’s degree in Chemical Engineering or a closely related engineering discipline.
8+ years of process or process systems engineering experience.
Minimum 5 years of substantial hands-on P&ID development experience, beyond review or approval responsibilities.
Demonstrated experience taking P&IDs through at least two major project phases, such as conceptual design, detailed engineering, construction/IFC, commissioning, or as-built.
Experience serving as P&ID owner, lead developer, or responsible process engineer on at least one significant industrial process project.
Demonstrated ability to develop P&IDs for complete process systems, including equipment, piping, valves, instrumentation, controls, safeguards, relief systems, vents, drains, and utility interfaces.
Experience leading multidisciplinary P&ID reviews and resolving comments across engineering disciplines.
Strong knowledge of fluid flow, heat transfer, process equipment, process controls, hydraulics, and process safety.
Ability to initiate, lead, and uphold safety policies, practices, procedures, and housekeeping standards.
Successful completion of pre-employment drug screening, including urine and hair follicle testing, is required.

Nice To Haves

5+ years of direct experience developing P&IDs for cryogenic ASUs or industrial gas facilities.
Demonstrated P&ID ownership for at least one ASU project from detailed design through commissioning or as-built status.
Experience with oxygen, nitrogen, and argon systems, cryogenic distillation, brazed aluminum heat exchangers, molecular sieve purification, compressors, expanders, and cryogenic pumps.
Familiarity with applicable ASME, API, CGA, NFPA, OSHA/PSM, IEC, and ISA requirements and practices.

Responsibilities

Serve as the technical owner and primary engineering authority for project P&IDs, maintaining technical integrity and consistency throughout the project lifecycle.

Translate PFDs, heat and material balances, equipment requirements, operating philosophies, and process design criteria into complete P&IDs.
Define piping, equipment, isolation, bypass, vent, drain, relief, instrumentation, control, alarm, trip, shutdown, and safeguarding requirements.
Lead formal multidisciplinary P&ID reviews and resolve comments and technical interfaces.
Incorporate vendor information, HAZOP/PHA actions, design changes, field modifications, and commissioning discoveries into controlled P&ID revisions.
Perform field walkdowns and reconcile engineering drawings against installed systems to support accurate as-built documentation.
Establish and maintain P&ID standards, symbology, design conventions, checklists, and quality requirements.
Mentor engineers and designers in P&ID development and review.
Participate in or lead HAZOP/PHA and other process safety reviews.
Support equipment specification, technical bid evaluation, vendor reviews, construction, commissioning, startup, performance testing, and troubleshooting.
