About The Role and Team Quantum Motion is a fast-growing quantum computing start-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 have recently moved into a new office in Islington with state of the art cryogenic facilities and have an outstanding interdisciplinary team spanning quantum physics to IC design. Our Team 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. Functions of the Role The primary function of this position will be to undertake CMOS RF IC designs implementing functionalities at the deep-cryogenic temperature regime. In this role you will be part of the IC Design team. The goal of the team is to design circuits that interface with quantum devices. No background in quantum physics is required. This is a rare and exciting opportunity to be an early employee at a start-up shaping the future of quantum computing, and in particular to form a new team within the company. There are vast opportunities for professional growth and to make an impact within the company. Architecture-level design of low power Tx chain. Block-level schematic design (pre and post layout) of RF Blocks such as LNA, PLL, LO, Mixer, VGA, Filters (depending on experience). Provide guidance for the layout of designed blocks and review layout work. Document own work for peer-review and perform design reviews of other team members work. Support the post-silicon validation and characterization of designed RF blocks. Experience - Essentials Experience in heavy research-oriented environments Demonstrated experience of CMOS RF IC design in sub-10GHz frequencies for low power systems.
