Product Development Technician

About the Role 

Maybell Quantum is redefining the future of computing. As a venture-backed quantum hardware innovator experiencing rapid growth, we're building technology that will transform industries for decades to come. Quantum computers will be as transformative to the next 30 years as the internet was to the last 30 — and our team is creating the hardware foundation to make this revolution possible. 

We are seeking a hands-on Product Development Technician to support the build, test, and iteration of our cryogenic systems and quantum hardware products. This is a critical role at the bench level of our product development lifecycle — you will be the person who physically assembles, characterizes, and helps validate the hardware that our customers depend on. Working closely with our engineering, product, and quality teams, you will help bring new products from prototype to shippable, production-ready state. 

This role is ideal for someone who thrives in a fast-paced startup environment, takes pride in meticulous hands-on work, and is excited to contribute directly to some of the most advanced hardware being built anywhere in the world. 

What You'll Do 

Assembly & Build 

• Assemble and integrate cryogenic hardware prototypes, including next generation dilution refrigerators and associated components. 

• Follow and contribute to work instructions, assembly procedures, and build travelers to ensure consistent, high-quality builds. 

• Perform precision mechanical assembly tasks including torque-to-spec fastening, leak-tight plumbing connections, and careful handling of sensitive cryogenic and vacuum components. 

• Prepare and manage hardware kits and bill-of-materials (BOM) staging for build activities. 

Testing & Characterization 

• Execute functional and acceptance tests on assembled hardware prototypes 

• Operate test equipment including leak detectors, vacuum gauges, multimeters, oscilloscopes, and data acquisition systems. 

• Collect, record, and organize test data in a clear and traceable manner, flagging anomalies or out-of-spec results to the engineering/product team. 

• Support cooldown and warm-up cycles on dilution refrigerator systems, monitoring system behavior and logging relevant parameters throughout. 

Iteration & Continuous Improvement 

• Provide hands-on feedback on design for assembly (DFA) and design for manufacturability (DFM), surfacing practical build and test challenges to the engineering and product teams. 

• Assist in the root cause investigation of hardware failures or test escapes, participating in teardown and failure analysis activities. 

• Support the development and refinement of assembly procedures, test scripts, and inspection checklists as products mature from prototype to production. 

• Help identify and implement process improvements that improve build efficiency, quality, or repeatability. 

Cross-Functional Collaboration 

• Work closely with mechanical engineers, cryogenic SMEs, and the product leadersihp to execute build and test plans aligned with the product development roadmap. 

• Participate in design reviews, build readiness reviews, and production handoff discussions, contributing a technician's perspective on practicality and workmanship. 

• Collaborate with supply chain and operations to receive, inspect, and manage incoming hardware and consumables. 

• Support customer system installations and on-site commissioning activities as required 

Who You Are 

• 3+ years of hands-on experience as a technician in a hardware development, manufacturing, or laboratory environment  

• Demonstrated experience with precision mechanical assembly, including working with small fasteners, fluid/vacuum fittings, and sensitive electromechanical components. 

• Experience operating and interpreting results from standard lab and test equipment (multimeters, leak detectors, vacuum gauges, oscilloscopes, etc.). 

• Strong attention to detail and a commitment to workmanship quality — you take pride in clean, correct builds. 

• Ability to read and work from engineering drawings, schematics, assembly procedures, and BOMs. 

• Clear and organized written communication skills for test data recording, build notes, and discrepancy reporting. 

• Comfortable working in a fast-paced startup environment where priorities evolve and ambiguity is part of the job. 

Preferred 

• Experience working with cryogenic systems, vacuum systems, or dilution refrigerators — even partial or adjacent experience (e.g., liquid nitrogen or liquid helium handling) is a plus. 

• Familiarity with clean room or cleanroom-adjacent handling procedures for sensitive optical, electrical, or vacuum components. 

• Experience in scientific instrumentation, aerospace, semiconductor, or advanced manufacturing environments. 

• Exposure to RF/microwave connectors, cabling, and handling procedures. 

• Associate's degree or technical certification in a relevant field (Mechanical Technology, Electromechanical Technology, Engineering Technology, or similar). Equivalent hands-on experience is equally valued. 

Why Maybell Quantum 

Build hardware that matters 

You won't be assembling commodity products. Every system you build at Maybell sits at the frontier of quantum computing — operating at temperatures colder than outer space and enabling experiments that were impossible five years ago. Your hands-on work directly enables scientific breakthroughs and the long-term future of computing. 

• Competitive compensation and equity participation. 

• Comprehensive health, dental, and vision benefits. 

• A collaborative, transparent, and high-performance team culture. 

• Direct exposure to world-class cryogenic engineering and quantum hardware development. 

• Opportunity to grow with a rapidly scaling company from the ground floor. 

This is a non-exempt FT role. The hourly rate is $32-$40, based on experience.
