What you will do

• Own process engineering scopes for complex, semi-ambiguous systems from early concept through engineering, construction, commissioning, and operation.
• Develop process design bases, operating envelopes, PFDs, heat and material balances, utility balances, P&IDs, process datasheets, and control philosophies.
• Apply chemical engineering fundamentals and steady-state or dynamic process models to define system architecture, operating boundaries, and equipment selection.
• Size, specify, and evaluate equipment with suppliers, fabricators, EPC organizations, contractors, and multidisciplinary engineering teams.
• Lead HAZOPs, design reviews, relief and depressurization studies, commissioning plans, test procedures, start-up strategies, and performance testing.
• Troubleshoot operating equipment using first-principles engineering and field data, manage project risks, drive solutions, and mentor less-experienced engineers.

Requirements

• Bachelor’s degree in Chemical Engineering or a closely related discipline.
• 10+ years of relevant industrial process engineering experience, potentially fewer with a PhD, or equivalent demonstrated depth of experience.
• Deep domain or broad cross-domain expertise, with the ability to independently own complex, semi-ambiguous work.
• Strong chemical engineering fundamentals and experience taking systems through structured FEL or phase-gated development.
• Experience scaling loosely defined process requirements into commercial-scale equipment and facilities.
• Expertise with process design bases, PFDs, P&IDs, heat and material balances, industrial equipment sizing and selection, commissioning, operation, and troubleshooting.
• Proficiency with process simulation tools such as EcoSim, Aspen HYSYS/Plus, or AVEVA, and experience with ASME B31.3, ASME BPVC Section VIII, API 520/521, and related industry standards.
• Strong process safety, hazard identification, risk analysis, HAZOP, and relief-system design experience; ability to integrate disciplines and work with vendors, EPC organizations, or construction contractors.
• Ability to lift up to 50 lbs occasionally; perform stooping, climbing, typing, standing, and extended sitting; work hands-on in industrial, construction, commissioning, and operating environments; and comply with export control laws.

Nice to have

• Experience with large-scale cryogenic systems, especially supercritical or liquid helium, and industrial high-vacuum systems.
• Background in power generation, petrochemical, LNG, industrial gas, nuclear, or other large-scale process facilities.
• Expertise in steam, molten salt, industrial gas processing, fueling, cooling water, chilled water, compressed or instrument air, and nitrogen utilities.
• Experience scaling first-of-a-kind technologies from pilot or demonstration scale to commercial operation, dynamic process simulation, or consequence analysis.
• Professional Engineer license.

Culture & Benefits

• Values include integrity, execution, impact, self-critique, safety, and diverse perspectives.
• Equity, competitive compensation, health, dental, and vision insurance, and a 401(k) with employer matching.
• Thirteen company-wide holidays, flexible vacation days, ten sick days, and generous parental leave.
• Professional growth opportunities and team-building activities.
• Work may involve heat, cold, noise, fumes, strong magnets, lead, high voltage and current, pressure and vacuum systems, hazardous materials, and cryogenics.
