Senior DevOps Engineer in London

About The Role and Team

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 optimising 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. As a Senior DevOps Engineer, you will bridge the gap between high‑level strategy and hands‑on execution. This role requires a robust software engineering background, a diagnostic problem‑solving mindset, and a relentless passion for automation. Given our hybrid footprint, this position offers the unique challenge of managing both cloud‑native services and physical on‑site infrastructure.

Our Team

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 the New 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, and we have recently closed our Series C funding of $160 million. 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 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).

Functions of the Role

• Design and manage large‑scale HPC clusters using cloud‑based services, optimising for CAD workloads.
• Implement Infrastructure as Code (IaC) with Terraform/CloudFormation to automate the provisioning of specialised EC2 instances for low‑latency networking.
• Architect and maintain high‑performance storage solutions, ensuring seamless data synchronisation and high‑IOPS throughput.
• Automate the deployment and scaling of job schedulers (e.g., PBS, Slurm, etc.) and manage cloud‑based license servers to ensure high utilisation and cost‑efficiency.
• Enforce strict security protocols within the HPC environment, implementing Zero Trust architectures and hardened Linux images specifically tuned for EDA tool compatibility and performance.
• Provide expert‑level support for complex CAD tool environment issues, documenting specialised workflows and mentoring junior staff on the nuances of high‑concurrency cloud environments.

Experience - Essentials

• Proven track record of architecting and deploying production HPC workloads on AWS using AWS ParallelCluster, SOCA or custom Slurm fleets.
• Deep expertise in Terraform (preferred) or CloudFormation for building modular, version‑controlled environments specifically tuned for compute‑heavy stacks.
• Advanced knowledge of high‑performance storage such as Amazon FSx for Lustre, NetApp ONTAP (FSxN) and EFS.
• Professional proficiency in Python or Bash for automating EDA job submissions, custom monitoring scripts, and complex integrations with other services.
• Deep understanding of IAM patterns, specifically focused on Active Directory/LDAP integration; Ability to translate complex HPC scaling decisions into actionable guidance for design engineers and cost‑benefit updates for leadership.

Experience - Desirable

• Ability to architect for cost efficiency, implementing automated spot‑instance interruption handling and Reserved Instance/Savings Plan optimisation for massive compute bursts.
• Proficiency in monitoring HPC cluster health and job performance using Prometheus, Grafana, or CloudWatch, with a focus on identifying I/O bottlenecks.
• Experience implementing technical controls and automating audit logging across hybrid compute environments.

Certifications: AWS Certified Solutions Architect Professional, AWS Certified Data Engineer, or AWS Certified Advanced Networking.
