Senior Software Infrastructure Engineer

About The Role and Team

Quantum Motion is a fast-growing quantum computing scale-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.

Since 2021 our team has been listed every year in 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 theNew 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 across London, Oxford, San Sebastián and Sydney, with our primary hub in Islington (London).

The Cloud Engineering Team builds cloud-based solutions, supports the cloud platform and helps to drive its adoption and expansion while also collaborating with other teams. Furthermore, the Cloud Engineering Team looks after the on‑prem IT infrastructure.

The primary function of this position will be to take responsibility for the successful development, management and maintenance of software services to ensure that the production services perform effectively, while maintaining a high level of internal customer satisfaction. This includes developing, maintaining, supporting, and optimizing key functional areas, particularly internal applications and servers in a hybrid infrastructure. You will develop, troubleshoot and resolve software and process problems in a timely and effective fashion.

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.
