Full Time Cryogenics Engineer - Singapore Jobs, in Maybell Quantum Industries - Maukerja

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 team to elevate our products, drive customer success from installation through long-term operation, and deliver an exceptional customer experience.

What You'll Do

Test, Validate, & Iterate

• Develop Test Plans: Build 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 Troubleshoot: 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 tests 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.
