Cryogenic R&D Engineer

Role Overview

You will join the Cryogenic Engineering R&D team, supervised by the Staff Cryogenic Engineer.

This team ensures the smooth running of our UK operations, managing state‑of‑the‑art facilities consisting of 7+ cryogenic fridges, whilst also overseeing off‑site lab deployments and installations.

This position is ideal for a cryogenic engineering specialist with an interest in quantum who enjoys a fast‑moving, collaborative environment with constantly evolving technical challenges.

You will be responsible for design, development, characterisation and troubleshooting of key cryogenic components such as superconducting magnets, RF and DC wiring looms and innovative quantum chip‑cooling technologies for use in dilution refrigerator systems.

You will be working with a team of like‑minded cryogenic and electronics engineers and researchers with whom you will be sharing ideas on a daily basis.

Working collaboratively towards achieving the company goal of a utility‑scale fault‑tolerant quantum computer.

This is a rare and exciting opportunity to be an early employee at a scale‑up shaping the future of quantum computing.

There are vast opportunities for professional growth and to make an impact within the company.

Responsibilities

• Cryogenic R&D: Developing new and innovative approaches to ultra low temperature signal transmission, sample cooling, miniature superconducting magnets, cryostats and other key components required to build a quantum computer.
• Test and measurement: Take control of test and characterisation protocols for cryogenic and electronics components and sub‑assemblies, ensuring repeatability and quality control.
• Lab User support: Giving fast and efficient support to our team of research scientists to develop and maintain our experimental setups (more than 20 to date and growing) to meet constantly evolving requirements.
• Production Support: Your cryogenic R&D work will feed directly into our production department and will require the development of robust assembly and test methodologies.
• Supervision & Mentoring: Act as a reference point for our apprentices and other technical team members, supporting them with advice and training to build essential skills in Cryogenic engineering.

Qualifications

• Academic experience: A higher degree (masters or Ph D level) in a relevant discipline involving low‑temperature quantum measurements or equivalent industry experience.
• Technical background: R&D/production experience in a commercial or laboratory environment. Familiarity with dilution refrigeration.
• Creativity: Proven expertise and demonstrable passion for inventing things.
• Design: Experience working with CAD software, prototyping and communicating technical information with relevant stakeholders.
• Mentorship: Experience in training, supervising and inspiring junior staff or apprentices.
• Problem solving: A strong intuition for hardware debugging and a proactive approach to installation and site work.
• Engineering: Deep understanding of cryogenic methods and material properties. Experience working within Quantum industry Lab support experience.
