Senior DevOps Engineer at Quantum Motion, London, UK, San Sebastián, ES. A senior-level full time position in the Cloud Engineering team, listed under software engineering.

About The Role and Team

Quantum Motion is a fast-growing quantum computing scale-up based in London founded by internationally renowned researchers from UCL and Oxford University with over 40 years’ experience in developing qubits and quantum computing architectures. Bringing together state-of- the-art cryogenic facilities and an outstanding interdisciplinary team, we are developing quantum processors based on industrial-grade silicon chips, with the potential to radically transform computing power in areas such as materials modelling, medicine, artificial intelligence and more.

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.

Requirements

• 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.

Nice to Have

• 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.
