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 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. 

Functions of the Role 

• 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 in heavy research-oriented environments
• Demonstrated experience of CMOS RF IC design in sub-10GHz frequencies for low power systems.
• Industry degree qualification and at least 5+ years of work experience in RF IC Circuit Design
• Demonstrated experience in circuit design on or below CMOS 40nm RF processes.
• Demonstrated experience with the Cadence Design environment and SpectreRF.
• Solid understanding of the fundamentals of RF design. Capable of providing feedback on the validity of the working principles of a circuit without the assistance of simulation software.
• Understanding of RF testing and demonstrated experience in the application of DFT of RF blocks.
• Knowledge of one or more industry-standard EM simulation toolset (ADS, EMX, CDT, HFSS)
• Strong analytical and problem-solving skills with a high-level of self-management and self-motivation
• Excellent verbal and written communication skills

• Experience in block-level Layout
• Knowledge of Verilog-A
• Demonstrated experience of MOSFET device modelling frameworks (BSIM preferred)
• Programming knowledge (Python, SKILL preferably)
• Knowledge of CMOS fabrication technology

• Be part of a creative, world-leading team
• Competitive salary and share options scheme
• Contributory pension scheme
• Private Medical Insurance
• Life Assurance
• Cycle-to-work Scheme 
• Flexible working
• Central London location
