Site Reliability Engineer

Site Reliability Engineer (Quantum Control Systems): Location: Japan Job Summary: As we move from "experiment support" to building an actual machine, the control stack must become reliable enough to run as a product. You will own that reliability - the maintenance, monitoring, deployment, and upgrade path for our quantum control system, across both development and production environments - so that senior engineers stay on the roadmap instead of firefighting, and the machine can move toward continuous, day-long operation. This is a 0→1 operations role. There is no existing ops foundation; you build it. Expect incomplete requirements and shifting constraints. You'll make progress with sound engineering judgment and harden things as the system stabilizes - not wait for a perfect spec. Responsibilities: Build CI/CD, build, and release automation for the control software stack Stand up monitoring, observability, and alerting across the control system and the lab's environmental sensor infrastructure (temperature, vibration, humidity nodes) Build hardware-in-the-loop (HIL) test automation so control-stack changes are validated against the real devices before they ship Drive system reliability: incident response, root-causing, and removing recurring maintenance toil from the engineering teams Own deployment, configuration management, and the upgrade/rollback path Automate regression and validation so changes to the control stack ship safely Scope boundary: partner with the network engineer on lab/infra networking - you own software reliability and deployment, they own the network fabric Partner with the Architecture group on the path to product-level reliability and the next-generation machine's target of continuous operation Required Qualifications: 5+ years in SRE, DevOps, or systems engineering, with demonstrated ownership of production reliability CI/CD and build/release automation Monitoring / observability tooling (metrics, logs, alerting) Python (or equivalent) for automation and tooling Strong Linux fundamentals Business-level English for a global team Self-directed learner comfortable ramping into an unfamiliar (quantum / physics) domain Preferred Qualifications: Infrastructure-as-code (Ansible, Terraform) Containers and orchestration (Docker, Kubernetes) Time-series monitoring stacks (Prometheus / Grafana) and dashboarding Experience operating scientific instruments, lab systems, or hardware-in-the-loop setup Networking fundamentals Experience with high-reliability or 24×7 systems Interest in quantum computing / physics Why this role: Define how a quantum computer is operated and kept alive - from zero Directly unblock the roadmap by taking operational load off senior engineers Own a hard, concrete target: move the machine toward continuous operation Founding-era scope with a clear path into the new quantum computer architecture group
