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 together 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. This is a rare and exciting opportunity to be an 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. Our team of 100+ is based across London, Oxford, San Sebastián and Sydney, with our primary hub in Islington (London). Functions of the Role 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. Functions of the Role • Design, provision, and manage large-scale, highly available cloud infrastructure platforms, optimizing for heavy compute workloads and high-concurrency applications. • Implement and maintain modular IaC (Terraform or CloudFormation) to automate the provisioning of secure, low-latency, and multi-region cloud environments. • Architect and maintain high-performance, high-IOPS cloud storage solutions, ensuring seamless data synchronisation, backup strategies, and optimal throughput. • Automate the deployment, configuration, and auto-scaling of workload orchestrators, container platforms, and core service components to ensure high resource utilisation and cost efficiency. • Enforce strict security protocols across all environments by implementing Zero Trust architectures, secure IAM roles, and automated configuration management (e.g., Ansible, Packer) for hardened OS images. • Provide expert-level support for complex infrastructure and platform issues, documenting automated workflows and mentoring junior team members on cloud-native best practices. Experience - Essentials • Proven track record of architecting, deploying, and maintaining production-grade, highly scalable workloads on AWS. • Deep expertise in Terraform (preferred) and CloudFormation for building modular, version-controlled infrastructure environments. • Solid knowledge of high-performance and distributed cloud storage solutions (e.g., Amazon FSx, EFS, EBS, NetApp ONTAP). • Expert-level proficiency with Enterprise Linux distributions (RHEL/Rocky/Ubuntu) and systems-level troubleshooting. • Professional proficiency in Python or Bash for building automation tooling, custom monitoring scripts, and complex system integrations. • Deep understanding of enterprise IAM patterns, including Active Directory/LDAP integration for consistent access control across hybrid environments. • Ability to translate complex infrastructural scaling decisions into actionable guidance for development teams and cost-benefit updates for leadership. Experience - Desirable • Proven track record of architecting and deploying production HPC workloads on AWS using AWS ParallelCluster, SOCA or custom Slurm fleets. • Ability to architect for maximum cost efficiency, implementing automated spot-instance utilization, auto-scaling strategies, and Savings Plans optimization. • Proficiency in monitoring infrastructure health and application performance using tools like Prometheus, Grafana, ELK stack, or CloudWatch, with a focus on identifying bottlenecks. • Experience designing and implementing automated CI/CD pipelines (e.g., GitLab CI, GitHub Actions, Jenkins) for software and infrastructure deployment. • Certifications: AWS Certified Solutions Architect Professional, AWS Certified DevOps Engineer Professional, or AWS Certified Advanced Networking.
