Job summary

IonQ, Inc. in Oxford, UK is seeking a Staff Platform Engineer to join the Quantum System Infrastructure team.

You will own the platform used by engineers and scientists to build, test, and deploy quantum systems, applying DevSecOps to deliver reliable, secure infrastructure on-site and in the cloud. As a senior team member, you will shape clusters, pipelines, monitoring, and remote development environments, collaborating with physicists, firmware and software engineers, IT and production SRE.

Qualifications

• 5+ years in a Platform, DevOps or Site Reliability role, running Linux systems in production
• Infrastructure as code with Terraform or OpenTofu
• Running containerised workloads on Kubernetes in production
• Building and speeding up CI/CD pipelines, ideally in GitHub Actions
• Observability and security for production systems: monitoring, alerting, secrets and access control

Responsibilities

• Run and evolve the Kubernetes platform behind each quantum system, and the release process that promotes software onto it (k3s, ArgoCD, Helm)
• Make CI faster and more reliable for every engineer, including our scarce hardware-in-the-loop and FPGA build runners and build caches (GitHub Actions)
• Make our systems observable: define dashboards and alerts as code for quantum system hardware such as lasers, cryogenics and vacuum, and move them onto IonQ's shared observability platform with our production Site Reliability Engineering (SRE) colleagues (Grafana, OpenTelemetry)
• Give every engineer and physicist a ready-to-use remote development environment, on-site or in the cloud, that works with our quantum system hardware
• Keep our on-site and cloud infrastructure secure, recoverable, reproducible and reviewable as code (OpenTofu, Atmos), from secrets and access to certificates and identity, and work with IonQ's infrastructure team on shared cloud services
• Lead technical decisions and write the runbooks and guides that let other teams change the platform safely themselves
