What You’ll Do:

We are seeking a Senior Process Systems Engineer to serve as the technical owner for Process & Instrumentation Diagrams (P&IDs) for cryogenic air separation projects.

The successful candidate will have significant hands-on experience developing, owning, and maintaining P&IDs from initial 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.

This engineer will be accountable for ensuring P&IDs accurately translate process design intent into safe, operable, maintainable, and constructible process systems and will lead P&ID coordination across process, mechanical, piping, instrumentation and controls, safety, suppliers, construction, commissioning, and operations.

Primary Responsibilities

• Serve as the technical owner and primary engineering authority for project P&IDs, maintaining technical integrity and consistency throughout the project lifecycle.
• Personally develop and direct P&ID development from conceptual design through detailed design, IFC/construction, commissioning, redlines, and final as-built status.

• 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.

Nice to Have:

• 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.
