About Us Maybell Quantum is building the hardware foundation of the quantum era. Our redesigned dilution refrigerator gives labs more fridges per room, more experiments per fridge, and a level of reliability and usability the field has never had. We are a fast-growing, venture-backed team of scientists and engineers, and the cryogenic systems we design in Denver ship to leading quantum computing groups around the world. We are seeking a Cryogenics Engineer to test , validate, troubleshoot , and refine our products and the subsystems that comprise them . You will work alongside our R&D scientists, mechanical and electrical engineers, and manufacturing tea m to elevate our products , d rive customer success from installation through long-term operation , and delive r an exceptional customer experience . What You'll Do Test , Validat e, & Iterate
- Develop Test Plans : B uild comprehensive experiments that push our products to the limit to ensure the highest quality standards — and to find ways for “ the best to perform even better. ”
- Operate and T roubleshoot: Become the equivalent of a “test pilot” for the most advanced cryogenic systems in the world , with a heavy focus on evaluating the user experience and risks to uptime.
- Drive Innovation : Work with our product and engineering teams to refine our platforms ’ designs based on your te sts and discoveries. Support our Customer Success Team
- Support Global Operations: Partner with our customers to root-cause and solve issues , allowing them to achieve the next breakthrough in quantum computing. Occasionally travel on site to assist when required .
- Build our Customer Success Infrastructure: Document test, and inspection procedures to ensure a common standard across the company and the highest level of customer support . Safety & Standards
- Engineer for Safety: Apply pressure-safety, relief-sizing, and oxygen-deficiency hazard practices to systems that handle helium-3/helium-4 mixture, liquid nitrogen, and high vacuum. Who You Are Required:
- Bachelor's degree (or higher) in mechanical engineering, physics, or an equivalent technical field.
- 3+ years of hands-on experience designing, building, or operating cryogenic systems.
- Strong grounding in heat transfer, thermodynamics, and fluid mechanics at cryogenic temperatures, including low-temperature material properties.
- Hands-on experience with high-vacuum systems and helium leak detection.
- Experience safely handling cryogens such as liquid nitrogen and liquid helium.
- Proficiency in 3D CAD (SolidWorks preferred) and analysis tools such as Python, MATLAB, or ANSYS.
- Strong written and verbal communication skills .
- Self-starter who can drive results independently in a fast-moving environment.
- Able to work on-site in Denver, CO. Preferred:
- Experience designing, building, or significantly modifying dilution refrigerators or other sub-kelvin systems (ADRs, helium-3 systems).
- Master's degree or PhD in a relevant field.
- Experience with helium-3/helium-4 gas-handling systems.
- Experience with brazing, welding, indium seals, or other cryogenic joining and sealing methods.
- Background in quantum computing, scientific instrumentation, or superconducting hardware.
- Experience with pressure-system design under ASME or equivalent codes.
- Experience in a high-growth, venture-backed startup.
