Senior Manufacturing Engineer – Cryogenic Cooling System

VEIR • Woburn, MA

4d • $145,000 - $165,000

About The Position

VEIR is seeking a Senior Manufacturing Engineer to own the manufacturing strategy for their Liquid Nitrogen (LIN) cooling system. This system integrates a variety of cryogenic pumps, piping, and tanks. The role involves partnering with an external fabricator and the internal engineering team to transition this system from prototype to a scalable, high-quality, cost-effective production design. It is a hands-on, high-visibility position for someone who thrives at the intersection of design engineering, supplier management, and quality systems.

Requirements

• 7+ years of manufacturing engineering experience, with direct experience taking complex electromechanical or fluid systems from prototype to production.
• Hands-on welding experience (e.g., TIG welding on stainless steel) or strong working knowledge of weld processes, weld quality standards, and weld inspection methods.
• Cryogenics experience — familiarity with liquid nitrogen or other cryogenic fluid systems, vacuum-jacketed piping, cryogenic valves, and associated safety and handling considerations.
• Experience developing incoming inspection and final test/qualification plans for mechanical or fluid systems.
• Strong quality systems background — ISO 9001 (or equivalent) practices, PFMEA and control plans, non-conformance/CAPA management, and measurement systems analysis/gauge R&R.
• Familiarity with weld quality standards and NDE acceptance criteria, and the ability to read and assess WPS/PQR and inspection documentation.
• Comfort using data to drive quality decisions — SPC, process capability (Cp/Cpk), yield and defect Pareto analysis on low-volume, high-complexity builds.
• Experience managing or partnering closely with external fabricators or contract manufacturers on skid-mounted or complex assembled systems.
• Solid understanding of GD&T, root cause analysis (8D, 5-Why, fishbone), and DFM/DFA principles.
• Experience with pilot build management and transitioning designs into scalable production.
• Ability to travel to fabricator/supplier sites as needed.
• Bachelor's degree in Mechanical Engineering, Manufacturing Engineering, or a related field (or equivalent practical experience).

Nice To Haves

• Experience with data center or critical infrastructure cooling systems.
• Familiarity with Turbo-Brayton or similar cryogenic refrigeration/pump technologies.
• Experience with controls/instrumentation integration on skid-mounted systems.
• Quality certifications such as ASQ CQE/CQA, Six Sigma Black Belt, AWS CWI, or ISO 9001 lead auditor.
• Experience with ASME code-stamped fabrication and working with authorized inspectors.
• Working knowledge of relevant codes and standards (e.g., ASME B31.3, ASME Section VIII pressure vessel code, CGA cryogenic standards) is a strong plus.

Responsibilities

• Partner with a contract fabricator and internal mechanical/controls engineering teams to optimize the LIN skid design for lead time, cost, and quality.
• Own Design for Manufacturability (DFM) and Design for Assembly (DFA) reviews across the skid, piping, tank, and controls room integration.
• Define and implement a quality strategy for the system, including incoming material inspection/qualification and final system-level test and qualification plans.
• Own the quality plan for the system: PFMEA, control plans, inspection and test plans (ITPs), and critical-to-quality (CTQ) feature definition with measurement methods and acceptance criteria.
• Establish weld quality controls with the fabricator — WPS/PQR review, welder qualification, and NDE requirements tied to ASME B31.3 and applicable code requirements.
• Drive supplier quality: first article inspection (FAI/PPAP-style) approvals, source inspection, supplier audits, and corrective action follow-through on critical components.
• Build the as-built quality documentation package for each skid for internal and code acceptance.
• Develop test protocols to de-risk the system before it ships to the field.
• Lead pilot/first-article builds, driving root-cause resolution of build issues and feeding learnings back into design and process documentation.
• Build the production process plan in collaboration with the fabricator.
• Drive continuous improvement across pilot and early production builds toward the lowest sustainable cost, shortest lead time, and highest quality steady-state production design.
• Manage fabricator relationship and performance: capability assessment, quoting support, capacity planning, and issue escalation/resolution.
• Interface with supply chain to qualify critical component suppliers.
• Create and maintain manufacturing documentation: BOMs, process flow diagrams, inspection plans, and non-conformance/CAPA processes.

Benefits

• Healthcare coverage with 100% employer paid premiums for medical, dental, and vision
• 401(k) Retirement Savings Program
• 12 Company Holidays + unmetered PTO
• 12 Weeks 100% Paid Parental Leave for all new parents
• Stock Options
• Employee Assistant Program (EAP)
• Regular teambuilding, off-sites, and lunch & learns
