Senior Site Reliability Engineer/DevOps

Quantum computing holds the promise of humanity’s mastery over the natural world, but only if we can build a real quantum computer. PsiQuantum is on a mission to build the first real, useful quantum computers, capable of delivering the world‑changing applications that the technology has long promised. We know that means we will need to build a system with roughly 1 million qubits that supports fault tolerant error correction within a scalable architecture, and a data center footprint.
By harnessing the laws of quantum physics, quantum computers can provide exponential performance increases over today’s most powerful supercomputers, offering the potential for extraordinary advances across a broad range of industries including climate, energy, healthcare, pharmaceuticals, finance, agriculture, transportation, materials design, and many more.
PsiQuantum has determined the fastest path to delivering a useful quantum computer, years earlier than the rest of the industry. Our architecture is based on silicon photonics which gives us the ability to produce our components at Tier‑1 semiconductor fabs such as GlobalFoundries where we leverage high‑volume semiconductor manufacturing processes, the same processes that are already producing billions of chips for telecom and consumer electronics applications. We also benefit from the quantum mechanics reality that photons don’t feel heat or electromagnetic interference, allowing us to take advantage of existing cryogenic cooling systems and industry standard fiber connectivity.
In 2024, PsiQuantum announced two government‑funded projects to support the build‑out of our first Quantum Data Centers and utility‑scale quantum computers in Brisbane, Australia and Chicago, Illinois. Both projects are backed by nations that understand quantum computing’s potential impact and the need to scale this technology to unlock that potential. And we won’t just be building the hardware, but also the fault tolerant quantum applications that will provide industry‑transforming results.
Quantum computing is not just an evolution of the decades‑old advancement in compute power. Join the OS/Platform team as a Site Reliability Engineer (SRE) and keep our services healthy, observable, and fast. Partnering with the Platform Engineering group, you’ll own the day‑to‑day operation of our monitoring stack—Grafana, Prometheus, Loki, and Tempo—crafting dashboards that surface golden signals and drive real‑time insight. You’ll codify reliability through SLIs/SLOs, automate runbooks in Python, and lead incident response to maintain world‑class uptime across both on‑prem and AWS environments.
Build and maintain Grafana dashboards that visualize golden signals (latency, traffic, errors, saturation) for engineers and stakeholders.
Operate and tune our observability pipeline (Prometheus, Loki, Tempo) to ensure scalable, low‑latency telemetry ingestion and alerting.
Develop automation and self‑service tooling in Python/Bash to streamline alerts, runbooks, and operational tasks.
Collaborate with Platform and Product teams on capacity planning, performance testing, and change management.
Improve CI/CD health checks and release safety nets within GitLab.
Contribute to infrastructure as code (Terraform, Ansible) for monitoring stack deployments and upgrades.
Bachelor’s Degree or higher in Computer Science, Engineering or other related technical field.
5+ years in an SRE, DevOps, or Production Engineering role supporting distributed systems in production.
Solid scripting/automation skills in Python and Bash; familiarity with GitLab CI pipelines.
Working knowledge of AWS services, networking fundamentals, and load balancing.
Experience running incident response and writing actionable post‑mortems.
Familiarity with Infrastructure as Code (Terraform, Ansible) and configuration management.
comfortable acting as a generalist across infrastructure, application, and data layers.
