We are creating something that has never been built before. What we are doing is extremely hard, the classic moon shot. Few people in their life will be able to be a part of something like this, where if we are successful, the technologies we develop will solve some of the world’s most challenging problems and literally change the world. And that is something to be excited about!\nYour role and responsibilities:\n Xanadu is looking for a Cryogenic Engineer to lead designing, developing, and building Xanadu’s next generation cryostats as well as contribute to the build-out of our facility-level infrastructure. In this role, you won’t just design; you’ll own the entire hardware lifecycle, ensuring our cryogenic platforms are robust, scalable, and mission-ready. You will collaborate closely with internal teams, subcontractors, and external partners to design, configure, and improve deployable systems while providing operational support for existing platforms.\nWith your deep technical expertise and experience in low temperature engineering, hands-on expertise with cryostats and related technologies, you will play a critical role in designing and enhancing the performance and scalability of our detector systems necessary for our quantum architecture. This role requires a hands-on approach to low-temperature engineering and a proven ability to manage integration efforts across multidisciplinary teams, as well as the ability to work effectively across disciplines in a fast-paced environment.\nYou will take full ownership of their development, from concept through validation and deployment within large-scale cryostat systems.\nResponsibilities include:\n\nDevelop new and innovative cryostats for our photon detector systems\nIndependently operate and test cryogenic systems (e.g. He-4 evaporator based, dilution refrigerators) including performance metrics, maintenance, and troubleshooting \nWork with cryogenic liquid and gas systems to achieve optimized cooling requirements \nHelp deploy large-scale cryogenic facilities with high recovery and efficiency\nWork with our scientific and engineering teams to push the limits on state-of-the-arts detector technologies \nBasic qualifications and experience:\n\nMaster’s degree, in Mechanical Engineering, Applied Physics, or a closely related technical field with at least 5 years of cryogenic industry experience\nExperience leading and iterating on cryostat designs \nCAD and simulation experience for thermal/mechanical modeling (e.g. Solidworks) \nExtensive hands-on experience operating cryostats, including cooldowns, troubleshooting, and maintenance \nKnowledge and experience with high vacuum systems for cryogenic use\nLiquid cryogen handling and distribution experience \nKnowledge of design and fabrication of liquid heat exchangers \nExperience operating a variety of fridges including pulse tube, liquid-cryogen, sorption, and dilution refrigerators \nThermal and mechanical engineering simulation experience, including knowledge of low-temperature material properties \nSelf-motivated, comfortable working both independently and collaboratively with people of all disciplines on complex projects in a fast-paced environment\nDetail-oriented with positive attitude towards work \nExcellent interpersonal and written communication skills \nPreferred qualifications and experience:\n\n7+ years cryogenic industry experience \nExperience with statistical process control and quality management system reporting methods \nExperience writing Python code \nKnowledge of Canadian and international regulations and standards for pressure and electrical systems \nThis is for a new position. Your base salary will be determined based on your location, experience, and internal benchmarks. The base salary range is 150,000 - 200,000 CAD. You will also be eligible for equity and benefits.\nOur values are important. They are fundamental and lay the foundation for culture at Xanadu.
