About Us
Quantum Motion is a fast-growing quantum computing start-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. Bringing together 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 areas such as materials modelling, medicine, artificial intelligence and more.

Our Team 
We are one of the “Top 100 Startups worth watching” in the EE Times in 2021 and 2022, 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, 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 and quantum computing theoreticians 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 40+ is based in Oxford and London, with a centre of mass in our Islington lab and office.

The Role & Team

The Quantum Hardware Team specialises in designing, validating and operating quantum processors based on silicon industrial technology. The candidate will contribute to the development of superconducting multi-module assemblies for silicon spin qubit control and readout.

This is a rare and exciting opportunity to be an early employee at a start-up shaping the future of quantum computing. Being a small team and having a flat structure, this is a great opportunity to contribute to new developments within the field. There are vast opportunities for professional growth and to make an impact within the company.

Essentials (Must Haves) 

  • MSc or PhD degree in engineering, physics, or related field
  • Excellent understanding of RF concepts including TM-line theory, resonant structures, matching, two-port noise theory.
  • Practical experience with design of RF/microwave circuitry between DC to 10GHz.
  • Experience with operating test equipment including AWGs, IQ (de)modulators, Oscilloscopes, Spectrum Analysers, VNAs and setting up low noise measurements.
  • Demonstrated ability to debug RF circuitry up to 10GHz.
  • Experience with at least one simulation tool such as Keysight ADS, Sonnet, Ansys HFSS or CST Microwave.
  • Experience in building and setting up test fixtures at RF/Microwave frequencies.
  • Experience of working with multilayer PCB designs at GHz frequencies or working with layout personnel in an advisory capacity.
  • Minimum of 3 years experience in an academic/product-based RF design environment. 
  • Ability to independently design and carry out complex experiments; perform data analysis and preparation of technical reports and presentations 
  • Ability to work in a team.
  • Excellent verbal and written communication skills

Desirable (Nice To Haves)
