Job description

Platform Network Engineer

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 a Platform Network Engineer, you'll design, build and evolve the networking platforms that power OQC's cloud, lab and office environments. You'll help deliver secure, resilient and high-performance infrastructure that enables cutting‑edge quantum computing research, experimentation and commercial product delivery.

The Role

Working within our DevOps team, you'll be responsible for designing, implementing and maintaining network infrastructure across on‑premises and cloud environments. You'll collaborate with engineers across the business to deliver scalable networking solutions, automate infrastructure wherever possible, and continuously improve the resilience, performance and security of our platforms.

What You'll Be Working On

• Design, implement and maintain secure network infrastructure across cloud, lab and office environments.
• Deliver network upgrades, new deployments and infrastructure improvements in collaboration with DevOps and project teams.
• Build and maintain Infrastructure as Code solutions, dynamic documentation and network architecture standards.
• Implement network monitoring, performance optimisation and incident response to ensure highly available services.
• Strengthen network security through access controls, encryption, security reviews and collaboration with IT teams.
• Partner with internal stakeholders to design networking solutions that support research, engineering and product delivery.
• Mentor colleagues, share technical expertise and contribute to the continuous improvement of networking practices across OQC.

What We're Looking For

• Experience in a Network Engineering role supporting enterprise or production environments.
• Hands‑on experience configuring and managing firewalls, routers and switches.
• Experience provisioning and supporting cloud networking across Azure, AWS or GCP.
• Strong knowledge of LAN, WAN, software‑defined networking, TCP/IP, DNS and network monitoring tools.
• Experience using Infrastructure as Code tools such as Ansible and version control systems such as Git.
• Experience working with Linux and Windows operating systems.
• CCNA, JNCIA or equivalent networking qualification.
• A collaborative approach with excellent problem‑solving, adaptability and a passion for continuous improvement.
• Willingness to travel to UK and international OQC locations when required.

The 'Nice-to-Haves'

• Experience working in data centre environments.
• Experience designing networks for R&D or global production environments.
• Knowledge of Kubernetes networking, Docker, Terraform, BGP, Python or advanced Azure networking.
• Experience working across Platform or DevOps engineering.
• Experience mentoring engineers and supporting technical development.
• Degree in Computer Science or a related discipline, or equivalent practical experience.
• Experience working within scientific or high-performance computing environments.

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.
