Cambridge Quantum (CQ) is a global leader in quantum computing.  Our software helps our partners, collaborators, and clients to solve the most difficult problems in their industries through quantum computing. Our focus is in the areas of quantum chemistry, quantum machine learning, quantum algorithms and quantum encryption.

Our cybersecurity division is developing a number of quantum-related technologies to enhance the security of our enterprise customers. This includes the world’s only quantum random number generator (QRNG) that uses quantum computers to produce perfectly unbiased entropy.

We are looking for an experienced FPGA engineer to join our cybersecurity team. In this role, you will be part of the group that helps to develop practical quantum devices. You will work closely with your colleagues to develop the support electronics and software for our photonic systems. In addition, using your expertise and knowledge of FPGAs, microcontrollers and their uses in cryptography you will implement novel cryptographic schemes.
You don’t need to have quantum experience to apply for this role, but any background in this area is welcome. Our main goal is to find a high-performing developer who works well in a team and has significant experience working with FPGAs and microcontrollers.


    • Working effectively within an interdisciplinary team during rapid product development.
    • Programming FPGAs and microcontrollers for cryptographic applications.
    • Programming in a variety of languages, including (at least) C and C++.
    • Adapting to new programming languages and frameworks, as needed.
    • Ensuring code quality through development of automated tests and participation in peer reviews.
    • Providing guidance to junior colleagues.

Key Requirements/Skills

    • Experience with programming FPGAs and microcontrollers.
    • Hands-on experience working with high-frequency electronics.
    • Knowledge of low-level system timing and function.
    • Familiarity with standard collaboration tools, including Git, Jira and Confluence.
    • Excellent written and verbal communication.
    • Degree in Mathematics, Computer Science or another STEM subject.

Desirable Skills

    • Knowledge of cryptography and working with hardware security modules.
    • Basic level of understanding of how lasers and photodiodes work.
    • Developing dedicated electronics to interface with optical equipment e.g. lasers/detectors.
What is in it for you?

Working alongside a highly talented team, with leading names in the quantum computing industry. We offer a highly competitive package including equity participation, 28 day’s paid annual leave, a workplace pension and a positive approach to flexible working.
