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 Cryogenic Scientist. Successful candidates have a deep background in cryogenics, a focus on pulse tube cryocoolers, and demonstrated ability to transfer commercial or academic research to fast-paced innovation, prototyping, and deployment. Primary Responsibilities Provide leadership in the conception, design, development, and manufacture of pulse tube cryocooler hardware. Design and conduct experiments to test modifications to existing compressor and cold head configurations to increase cooling power, efficiency, and reliability. Partner with engineers to translate innovations into functional prototypes and production-ready cryocooler systems. Work across functional areas (cryogenic, mechanical, electrical) to deliver fully integrated cooling solutions. Qualifications Master's degree in a relevant field, or equivalent experience. 3-8 years designing, building, or significantly modifying pulse tube or Gifford-McMahon cryocoolers. Self-starter with the ability to drive results independently. Strong written and verbal communication skills. Don't meet every single requirement? Studies have shown that some people are less likely to apply to jobs unless they meet every single desired qualification. 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.
