Here at TreQ, we are accelerating the path to useful quantum computing by designing, deploying, and operating open-architecture quantum computing infrastructure that evolves as quantum technologies advance.

We are shaping the future of quantum computing and as we expand, we are searching for a Cryogenic Systems & Infrastructure Engineer. Based in Milton Park, Abingdon, your primary responsibility will be to ensure the reliable installation and operation of TreQ’s cryogenic systems and infrastructure at our manufacturing and innovation centre. As a Cryogenic Systems & Infrastructure Engineer with TreQ, you will be responsible for the full lifecycle of cryogenic systems — from shipment and delivery through installation, testing, and operation at TreQ, to preparation, transport, and installation at customer sites.

You will work closely with our engineers, operations teammates, and external partners to keep critical systems running and ready for use. This role is for someone who wants to take ownership of critical infrastructure systems, bringing them online, keeping them running, and seeing them deployed into the field.

As a Cryogenic Systems & Infrastructure Engineer, your day will include:

• Operating cryogenic systems and optimising uptime > driving systems to reliable performance through troubleshooting, coordination with manufacturers, and hands-on intervention
• Leading installation, commissioning, and bring-up of systems including integration with facility infrastructure and the validation of system readiness
• Establishing and maintaining facilities infrastructure, including cooling systems, chilled water, electrical systems, and access control
• Managing end-to-end system logistics and deployment, including coordinating shipment, customs, receiving, repackaging, and installation at customer sites
• Building and maintaining operational discipline, including creating documentation, organising workspaces, managing parts and consumables inventory, and defining repeatable operating procedures

Requirements

You will be a success in this role if:

You know about:

• Dilution refrigerators or closely related low-temperature systems
• Facility infrastructure required for advanced computing hardware systems (cooling, power, plumbing, environmental controls)
• System installation and commissioning in technical environments
• Working with equipment under warranty, including troubleshooting and escalation
• Safety practices and operational constraints in manufacturing environments

You can:

• Troubleshoot complex physical systems methodically in time-sensitive situations
• Work hands-on across mechanical, electrical, and system-level challenges
• Collaborate across internal engineers, business leads, vendors, and partners to resolve issues
• Stay organised and maintain clarity in environments that are initially unstructured
• Exercise judgement on when to intervene directly vs. coordinate or escalate

You’ve had experiences like these:

• Operating cryogenic, vacuum, and similarly complex physical systems
• Bringing new systems online, including early-stage troubleshooting
• Working with systems that were not yet stable or fully performing to specification
• Supporting deployment or installation of equipment at external sites
• Managing or contributing to facility or infrastructure setup for technical operations

You like:

• Working with others to solve complex, practical problems that don’t have clean documentation
• Keeping critical systems operating
• Working with your hands as much as your head
• Creating order and repeatable processes in environments that are still being built
• Seeing systems go from crates and components to fully operational

You can demonstrate:

• Deep experience with dilution refrigerators in quantum, low-temperature physics, or related environments
• Familiarity with CAD tools or working with machine shops for custom parts
• Experience supporting system deployments across multiple sites and customers

Here at TreQ, we value practical engineering experience as much as formal academic credentials. People join TreQ from industry, national laboratories, startups, academia, and military service.

TreQ is a veteran-owned, woman-owned small business and an equal opportunity employer. We hire based on capability, character, and the ability to contribute to our mission.

Work Location & Collaboration

TreQ is a hands-on engineering organisation tackling complex systems at the frontier of computing. This work requires close collaboration, trust, and rapid iteration, so most roles work primarily in person where our teams design, build, and operate systems together. Some hybrid flexibility may be available, though candidates should expect to spend the majority of their time on-site with teammates.

Export Control Work Authorisation Compliance

Some roles at TreQ involve access to technologies subject to export control laws in the United States, the United Kingdom, and other jurisdictions (including ITAR and EAR). Candidates for these roles must be eligible to access export-controlled technology without TreQ obtaining an export license. In accordance with applicable law, TreQ may also verify citizenship, immigration status, and the right to work where required. Certain roles may not be eligible for visa or export license sponsorship.

We believe that solving complex technical, scientific, and operational challenges requires a diversity of thought, background, and perspective. We are an equal opportunity employer committed to creating an inclusive, barrier-free, and supportive workplace where every team member can thrive and perform at their best.

We welcome applications from all qualified candidates regardless of age, disability, gender reassignment, marriage or civil partnership status, pregnancy or maternity, race, religion or belief, sex, sexual orientation, or socio-economic background. In full alignment with the UK Equality Act 2010, all hiring decisions are made strictly on merit, technical capability, and candidate potential. We want every applicant to have a positive, fair, and transparent recruitment experience. We are committed to making reasonable adjustments throughout all stages of our application, assessment, and interview process for candidates with disabilities, physical or mental health conditions, or neurodivergent requirements.

If you require any support, adjustments, or alternative information formats such as extended time for technical assessments, adjusted interview timings, accessible meeting spaces, or specific software compatibility, please inform our talent team
