About Xanadu: Xanadu’s mission is to build quantum computers that are useful and available to people everywhere. At Xanadu, we are learners, innovators, researchers, collaborators, and problem solvers. 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! Your role and responsibilities: Xanadu is seeking a Cryostat Technician to support our next-generation cryostats and ongoing low-temperature device development. In this role, you will ensure our cryogenic platforms are robust, scalable, and mission-ready. You will collaborate closely with the low-temperature devices, hardware operations, and packaging teams to support a high volume of device analysis while providing operational support for our existing platforms. With your technical expertise and hands-on experience with cryostats and related low-temperature technologies, you will play a key role in supporting the daily operations and performance testing of our detector systems necessary for our quantum architecture. This role requires a practical approach to low-temperature engineering and a proven ability to collaborate effectively with multidisciplinary teams in a fast-paced environment. You will assist in the assembly, testing, maintenance, and routine operation of large-scale cryostat systems. Responsibilities include: * Support the assembly, setup, and testing of new cryostats for photon detector systems * Operate and assist in testing cryogenic systems (e.g., He-4 evaporator-based), performing routine maintenance, performance logging, and troubleshooting * Work with cryogenic liquid and gas systems to achieve optimized cooling requirements * Assist in the maintenance and operation of large-scale cryogenic facilities to ensure safe and efficient gas/liquid recovery * Collaborate closely with scientific and engineering teams to support ongoing detector characterization and testing Required Qualifications and Experience: * Bachelor’s degree in Mechanical Engineering, Applied Physics, Technical/Engineering Technology diploma, or a closely related field with 2–3 years of hands-on cryogenics experience. * Practical experience assembling, testing, or assisting with cryostat operations * CAD and experience for mechanical part design or 3D printing (e.g. Solidworks) * Hands-on experience operating cryostats, including cooldowns, troubleshooting, and maintenance * Knowledge and experience with high vacuum systems for cryogenic use * Liquid cryogen handling and distribution experience * Self-motivated, comfortable working both independently and collaboratively with people of all disciplines on complex projects in a fast-paced environment * Detail-oriented with positive attitude towards work * Excellent interpersonal communication skills Preferred Knowledge and Experience: * 3+ years of hands-on experience in a cryogenic laboratory or industrial environment * Hands-on experience with silicon chip handling and mounting * Experience with fiber handling and routing * Experience writing Python code This is for a new position.
