Thermal Performance Engineer

Maybell Quantum is growing quickly, and we are expanding our team! If joining an outstanding team at one of the most exciting companies in quantum computing sounds interesting, then Maybell may be the place for you.


Maybell is a venture-backed startup of scientists, engineers, visionaries, and innovators designing and building the hardware that makes quantum science possible.


We are seeking an experienced  Thermal Engineer to help us develop next cooling infrastructure for quantum computers. Successful candidates will have a strong background in cryogenics and thermal engineering, with demonstrated ability to transfer commercial or academic research to fast-paced innovation, prototyping, and deployment.


Research and Analysis: Conduct in-depth research on potential solutions to specific cryogenic challenges, utilizing scientific literature and emerging technologies to inform design strategies.


• Modeling and Simulation: Perform comprehensive analysis and modeling to evaluate and determine the best solutions, employing computational tools (e.g., ANSYS, COMSOL, Python) for thermal and fluid dynamics simulations.


• Solution Implementation: Design and plan the implementation of selected solutions, creating detailed specifications for development and deployment.


• Cross-Functional Collaboration: Work closely with multidisciplinary teams (cryogenic, mechanical, electrical, software) to ensure seamless integration of designs into fully functional products.

Bachelor's or Master's degree in Mechanical Engineering, Physics, or a related field; 5-8 years of hands-on experience with liquid nitrogen and liquid helium systems, including designing, building, or significantly modifying cryogenic systems.


• Proficiency in heat transfer, thermodynamics, and fluid dynamics, with skills in designing mechanical systems that operate reliably at cryogenic temperatures.


• Knowledge of material science, especially how materials behave at low temperatures, and experience with stress analysis under thermal contraction.


• Familiarity with cryogenic equipment and instrumentation, including cryogenic thermometers and data acquisition systems.


• Experience with computational fluid dynamics (CFD), thermodynamic modeling, and material databases like REFPROP.


• Excellent written and verbal communication skills, with experience writing technical reports and documentation.


• Proven ability to work effectively in multidisciplinary teams and lead projects from concept to implementation.


• We are dedicated to building a diverse, inclusive, and authentic workplace, so if you're excited about this role but your experience doesn't align perfectly with every qualification in the job description, we encourage you to apply anyway.
