Cryogenic R&D Engineer
Cryogenic Engineer (Staff) at Quantum Motion
About The Role And Team
Quantum Motion is a fast-growing quantum computing scale-up based in London, founded by internationally renowned researchers from UCL and Oxford University with over 40 years’ experience in developing qubits and quantum computing architectures. Combining state-of-the-art cryogenic facilities and an outstanding interdisciplinary team, we are developing quantum processors based on industrial-grade silicon chips, with the potential to radically transform computing power in fields such as materials modelling, medicine, artificial intelligence, and more.
Since 2021, we have been featured in the "Top 100 Startups worth watching" in EE Times for 2021 and 2022. Our technology breakthroughs have been highlighted in The Telegraph, BBC, and The New Statesman. Our team includes founders who are pioneers in qubit and quantum computing architecture, while our chairperson is a co-founder of Cadence and Synopsys, the two leading companies in Electronic Design Automation. Backed by top-tier investors, we recently closed our Series C funding of $160 million.
We unite the brightest quantum engineers, integrated circuit (IC) engineers, quantum computing theoreticians, and software engineers to create a world-leading team. Our collaborative and interdisciplinary culture thrives in a cutting-edge research and development environment, focusing on solving big challenges and advancing scalable quantum computers based on silicon technology.
Our 100+-strong team is based across London, Oxford, San Sebastián, and Sydney, with our primary hub in Islington, London.
Our Team
You will join the Cryogenic Engineering R&D team, supervised by the Staff Cryogenic Engineer. This team ensures the smooth operation of our UK facilities, managing 7+ state-of-the-art cryogenic fridges, while also overseeing off-site lab deployments and installations.
This position is ideal for a cryogenic engineering specialist with an interest in quantum computing, excelling in a fast-paced, collaborative environment with constantly evolving challenges. Your responsibilities will include designing, developing, characterising, and troubleshooting key cryogenic components such as:
- Superconducting magnets
- RF and DC wiring looms
- Innovative quantum chip-cooling technologies for dilution refrigerator systems
