We are solving incredibly challenging problems at the cutting edge of physics and engineering. 

The Opportunity 

Maybell Quantum is seeking a Manufacturing Engineering Specialist to bridge the gap between Senior Production Technicians and Manufacturing Engineers. This is a highly hands-on role focused on building, troubleshooting, improving, and stabilizing manufacturing processes for dilution refrigerators. The position is ideal for a technically strong individual with an associate degree who demonstrates engineering aptitude, structured problem-solving skills, and ownership of manufacturing outcomes. 

This role is 100% hands-on and execution-focused, with increasing responsibility for process improvement, lean initiatives, and small project leadership.  

Key Responsibilities 

• Perform hands-on mechanical and electrical assembly and testing of dilution refrigerators and critical subassemblies
• Execute complex fabrication and rework while developing and refining manufacturing methods and procedures
• Serve as the primary technical problem solver on the production floor, leading root cause analysis and corrective actions
• Operate production equipment (ovens, presses, leak checkers, etc.) and drive improvements to safety, reliability, and throughput
• Own and lead manufacturing improvement initiatives, including yield improvement, defect reduction, and cycle-time reduction
• Support and mentor technicians by providing hands-on guidance, technical coaching, and troubleshooting support
• Create, maintain, and continuously improve work instructions, standard work, and visual aids
• Actively participate in Lean manufacturing systems, including tier meetings, daily management, and structured problem-solving
• Collaborate closely with Manufacturing Engineering, Quality, and Design Engineering to support design-for-manufacturing and change implementation
• Promote a strong culture of safety, quality, ownership, and continuous improvement 

 Required Skills and Experience 

• Associate degree in Mechanical Technology, Manufacturing Technology, or equivalent hands-on experience
• Minimum of 5 years of experience in an R&D, prototype, or manufacturing environment
• Strong hands-on experience building complex, precision mechanical and electromechanical assemblies
• Proficiency with machine shop equipment (mill, lathe, drill press, power tools, etc.)
• Experience operating and troubleshooting production equipment such as ovens, presses, and leak detection systems
• Demonstrated ability to perform mechanical and electrical troubleshooting using structured approaches
• Ability to interpret BOMs, manufacturing drawings, electrical schematics, and engineering documentation
• Strong attention to detail with a safety-first mindset
• Willingness to support off-hours work as required for builds, troubleshooting, or qualification activities 

Desired Skills and Experience 

• Experience with vacuum systems and vacuum leak checking
• Hands-on experience with pneumatics, pumps, valves, or high-voltage electrical systems
• Proven ability to work effectively with cross-functional teams (engineering, quality, supply chain)
• Working knowledge of Lean manufacturing principles, tiered accountability, and continuous improvement tools
• Experience leading or supporting small technical projects or improvement initiatives
• Familiarity with MES systems, CAD tools, Microsoft Office, and basic data analysis
