Quantum Motion is a fast-growing quantum computing scale-up based in London. We are developing quantum processors based on industrial-grade silicon chips, with the potential to radically transform computing power in areas such as materials modelling, medicine, artificial intelligence and more. We are based in Islington with state of the art cryogenic facilities and have an outstanding interdisciplinary team spanning quantum physics to IC design.

Since 2021 our team has been listed every year in the “Top 100 Startups worth watching”in the EE Times, and our technology breakthroughs have been featured in The Telegraph, BBC and the New Statesman. Our founders are internationally renowned researchers from UCL and Oxford University who have pioneered the development of qubits and quantum computing architectures. Our chairman is the co-founder of Cadence and Synopsys, the two leading companies in the area of Electronic Design Automation. We’re backed by a team of top-tier investors including Bosch Ventures, Porsche SE, Sony Innovation Fund, Oxford Sciences Innovations, INKEF Capital and Octopus Ventures, and we have so far raised over £62 million in equity and grant funding.

We bring together the brightest quantum engineers, integrated circuit (IC) engineers, quantum computing theoreticians and software engineers to create a unique, world-leading team, working together closely to maximise our combined expertise. Our collaborative and interdisciplinary culture is an ideal fit for anyone who thrives in a cutting-edge research and development environment focused on tackling big challenges and contributing to the development of scalable quantum computers based on silicon technology.

Our team of 100+ is based in Oxford and London, with a centre of mass in our Islington lab.

The IC Team is responsible for the design and test of the integrated circuits which operate at
deep-cryogenic temperatures and interact with the qubits. This role is a unique chance to work
at the bleeding edge of technology development where you will measure, optimise, and analyse
the performance of innovative circuits to tackle the engineering challenge of implementing a
large-scale quantum computer in silicon.

This is a rare and exciting opportunity to join a scale-up company shaping the future
of quantum computing. There are vast opportunities for professional growth and to make an
impact within the company.
