Senior Manufacturing Engineer – Cryogenic Cooling System

VEIR • Woburn, MA

3d

About The Position

VEIR is seeking a Senior Manufacturing Engineer to lead the manufacturing strategy for their Liquid Nitrogen (LIN) cooling system. This system incorporates various cryogenic pumps, piping, and tanks. The role involves collaborating with an external fabricator and the internal engineering team to transition the system from prototype to a scalable, high-quality, and cost-effective production design. This is a hands-on, high-visibility position for individuals skilled in 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, including WPS/PQR review, welder qualification, and NDE requirements tied to ASME B31.3 and applicable code requirements.
• Drive supplier quality through first article inspection (FAI/PPAP-style) approvals, source inspection, supplier audits, and corrective action follow-through.
• Build the as-built quality documentation package for each skid.
• Develop test protocols to de-risk the system before field deployment.
• 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, including 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
