Senior Process Engineer - Cryogenic Systems

Location: Woburn, Massachusetts, United States

Department: Engineering

In the first 3 months you'll

• Review and develop a working understanding of VEIR's cryogenic system designs, existing documentation, and outstanding technical questions.
• Complete engineering calculations or reports on at least two high-priority system problems, such as liquid nitrogen tank thermal management or manifold flow distribution.
• Build relationships with your cross-functional counterparts in mechanical, electrical, and systems engineering.
• Begin contributing to P&ID reviews, identifying gaps or inconsistencies in current design documentation. 

In the first 6 months you'll

• Own equipment specification and vendor qualification for one or more cryogenic subsystems, including selection of pumps, heat exchangers, tanks, or flow control components.
• Produce formal calculation reports or technical memos that support design decisions and are suitable for design review.
• Actively contribute to process safety reviews (HAZOP or equivalent) for relevant subsystems.
• Begin taking on design and analysis tasks within the 1.0 low voltage product program with limited oversight.

By the end of the first year, you will have

• Lead a cross-functional technical effort, coordinating internally and with external partners to resolve a complex system-level engineering question.
• Own the process engineering documentation library for assigned subsystems, including operating procedures, maintenance guidelines, and specification records.
• Be a recognized internal resource for cryogenic and thermal systems expertise, supporting design decisions across the 1.0 and HTS product lines.
• Demonstrate the ability to scope, structure, and independently drive engineering investigations from problem definition through to a documented, decision-ready output.

To be successful in this role

You bring:

• 6 to 8 years of experience in process or systems engineering, with a focus on thermofluids-intensive systems. Mechanical or chemical engineering degree required.
• Demonstrated proficiency in heat transfer, thermodynamics, and fluid systems design, including cryogenic or low-temperature applications.
• Hands-on experience reading, creating, and reviewing P&IDs and PFDs, with fluency in standard instrumentation and equipment symbols.
• Experience specifying and procuring major equipment items, including pumps, heat exchangers, cryogenic tanks, and associated controls.
• A track record of producing engineering documentation: calculation reports, equipment specifications, operating procedures, or design basis memos.
• Some exposure to process safety review methodologies (HAZOP, FMEA, or equivalent).
• Experience from oil and gas (specifically LNG), industrial gas, fusion energy, or space launch is directly relevant to the work here.

Nice to have:

• Direct cryogenic systems experience, specifically with liquid nitrogen, liquid hydrogen, or liquid oxygen handling.
• Field experience observing or participating in system construction, commissioning, or startup, and feeding those lessons back into design.
• Familiarity with the full project lifecycle: from concept and design through procurement, construction oversight, and commissioning.

You are:

• A systems thinker who can hold the full picture of a complex fluid system while knowing which details matter most.
• Comfortable working with ambiguity and incomplete information, structuring engineering problems before solving them.
• Skilled at communicating technical findings clearly in writing and in cross-functional settings.
• Energized by the pace and ownership that comes with an early-stage, high-impact deep tech environment.
• Collaborative and straightforward: you share what you know, ask when you don't, and hold yourself accountable to your commitments.
