Role:
We are looking for a Analogue Designer, CMOS Modelling to join our Cryo-CMOS IC team at IonQ based in our Oxford office. In this role, you will be responsible for owning full-chip mixed-signal CMOS modelling as a first-class part of our Cryo-CMOS development flow. This includes building the behavioural model of the chip that the whole team will simulate against, allowing the team to design, verify and validate the integrated circuits that control our quantum processors - the novel technology that sits at the very heart of our world-leading quantum computers. You will enable the team to work in conditions from room temperature down to a few kelvin. This work will allow the team to meet our research and development goals, contributing directly to our ability to deliver on our technological milestones.
In this role you’ll play an important part in shaping the modelling methodology, standards and sign-off criteria that support our work in building the world’s most advanced quantum systems.
Responsibilities:
In this position, you will work on deriving behavioural models from first-principles mathematics to support
