Workplace: hybrid

Description

At OQC, we aren’t just theorising about the future; we’re building it. Born from a philosophy of bold innovation, we’ve successfully transitioned quantum computing from an academic dream into a commercial reality.

The most exciting thing is that we’re just getting started and we’ve recently closed our £260 million Series C funding round – the largest fundraise ever completed by a quantum computing company in Europe.

The Purpose

As an IT Support Engineer, you’ll help keep OQC’s technology estate reliable, secure and ready to scale.

You’ll provide hands-on 1st and 2nd line support, contribute to more complex 3rd line issues, and make sure our teams have the technology, systems and support they need to do their best work.

This is an opportunity to go beyond ticket resolution: you’ll help improve how IT operates, strengthen our processes and contribute to the technology foundations of a growing quantum computing business.

The Role

Reporting to the Head of IT, you’ll take ownership of IT support across a varied environment spanning Windows, macOS, Linux, cloud platforms, networks and end-user hardware.

You’ll work closely with colleagues across IT and the wider organisation, managing issues through their full lifecycle while contributing to security, compliance, service improvement and cross-functional projects. You’ll also have opportunities to build your technical depth by collaborating with 3rd line specialists and working with emerging technologies.

What You'll Be Working On

Own 1st and 2nd line support requests from diagnosis through to resolution, working to agreed SLAs and escalating complex or high-impact issues when needed.
Troubleshoot and maintain a diverse IT estate spanning Windows, macOS and Linux desktop/server environments, cloud services, applications and end-user hardware.
Monitor IT systems proactively, identifying performance or availability risks and supporting incident, problem, backup, recovery and resilience processes.
Deliver smooth onboarding and offboarding while maintaining accurate records across hardware, software, licences and other IT assets.
Strengthen our IT knowledge base by maintaining clear documentation, sharing expertise and supporting the development of junior colleagues.
Improve how we operate by identifying opportunities to automate, streamline and strengthen systems and processes, researching emerging technologies and implementing approved changes.
Contribute technical expertise to cross-team projects, audits and security initiatives, ensuring work aligns with relevant policies, ISO standards and GDPR requirements.

What We're Looking For

Experience delivering 1st and 2nd line IT support, with exposure to 3rd line support, in an SLA-driven technical environment.
Strong troubleshooting capability across hardware and software, including Windows 10/11 and Windows Server, macOS, and Ubuntu Linux desktop/server environments.
Hands-on experience with modern workplace and cloud technologies such as Google Workspace, Microsoft 365 and Azure/Entra, alongside general application support.
Experience using ticketing, task tracking, documentation and support desk tools, with confidence maintaining IT documentation and knowledge bases.
Practical experience across IT asset management, endpoint management, software/licence management, backup and disaster recovery, and user onboarding/offboarding.
Understanding of incident and problem management, networking and cybersecurity fundamentals, with awareness of compliance frameworks such as ISO 27001 and GDPR.
A BSc in IT or a relevant discipline, or equivalent industry experience, combined with an adaptable, detail-focused approach and a strong commitment to quality.

The 'Nice-to-Haves'

Experience supporting global teams across multiple offices or working within a fast-moving start-up environment.
Exposure to high-performance computing or quantum computing environments.
Experience with Cisco or Juniper networks and firewalls, virtual machines, cybersecurity tooling and security best practices.
Scripting or automation experience using technologies such as PowerShell or Bash.
Experience contributing to IT projects, audits, compliance reviews or security assessments.
Familiarity with emerging technologies, including practical applications of AI within IT environments.
Certifications such as Microsoft or Linux certifications, Cisco CCNA, Juniper JNCIA, CompTIA Security+/Network+, ISO 27001, ITIL, or other relevant IT, networking or security qualifications.

Why Join OQC

You will join a world-class team at the forefront of the next computational era. We offer a culture of bold innovation, the chance to work with unique lab infrastructure, and the opportunity to see your work redefine the limits of computation.

About the company

Oxford Quantum Circuits (OQC) is a UK quantum computing company that builds superconducting quantum systems using its Coaxmon architecture and offers Quantum Computing as a Service through cloud access and colocated data centers. Its products work by using superconducting qubits implemented with the Coaxmon design, allowing users to run quantum programs remotely via a cloud interface or at partner data centers, with plans for larger TITAN systems aimed at fault-tolerant computing. What sets OQC apart from competitors is its specific Coaxmon architecture and its focus on scaling up infrastructure across international locations, backed by a large Series C funding round and strategic investors, to push toward practical, fault-tolerant quantum computing. The company’s goal is to expand its global infrastructure and develop next-generation TITAN quantum systems to achieve fault-tolerant quantum computing at scale.

Simplify's Take

What believers are saying

Bullhound Capital, British Business Bank, and Chevron funded OQC's £260 million June 2026 Series C.
Barcelona's €92 million manufacturing centre adds 210 jobs, expanding capacity and talent access.
OQC's June 2026 partnership with JPMorganChase and AMD validates demand from regulated buyers.

What critics are saying

Toshiko remains 32 physical qubits; enterprise value stalls until GENESIS proves usable by 2027.
JPMorganChase becomes first dedicated London user within twelve months, creating concentration and deadline pressure.
TITAN's 2028 fault-tolerant claims face brutal physics; failure would crush OQC's commercial narrative.

What makes Oxford Quantum Circuits unique

Coaxmon packaging puts wiring behind the chip, enabling denser superconducting systems.
OQC deploys quantum computers inside commercial data centres across the UK, Japan, Spain, New York.
GENESIS targets secure hybrid quantum-AI workflows with JPMorganChase and AMD in London.

OQC raises $330M as quantum computing shifts from research to critical infrastructure

Quantum computing firm OQC has completed a £260 million Series C funding round, positioning itself as one of the best-capitalised private quantum computing companies globally. Chief executive Gerald Mullally said the capital will enable OQC to expand internationally and build secure, scalable quantum infrastructure for enterprise and government customers. Mullally noted that recent public market activity, including Quantinuum's initial public offering, is helping build investor confidence in the sector. He described the developments as signalling a shift for quantum computing beyond research towards practical infrastructure. The funding will support OQC's technology roadmap, advancing its quantum processors and software platforms. Mullally indicated the company's strategy includes shaping the industry's next phase through technological innovation and strategic partnerships.

Oxford Quantum Circuits bags $348M ($350M) Series C, Europe's largest private quantum computing round

Oxford Quantum Circuits has raised £260m ($350m) in a Series C round, marking the largest funding for a private quantum computing company in Europe. The round was led by Bullhound Capital, with participation from British Business Bank, European investors including Fynveur and Cofides, and US and Singapore-based firms. The UK-based scaleup builds quantum computers using superconducting qubits and offers them as a service through partner data centres in London, Tokyo and New York. Customers buy computing time rather than purchasing systems outright, an approach particularly attractive to regulated sectors like finance and defence requiring secure data storage. The funding will support geographic expansion and development of next-generation systems. OQC's current most advanced computer has 32 qubits, with CEO Gerald Mullally stating the goal is building systems for the "commercial era of quantum".
