Job Description

PsiQuantum'smission is to build the first useful quantum computers-machines capable of delivering the breakthroughs the field has long promised. Since our founding in 2016, our singular focus has been to build and deploy million-qubit, fault-tolerant quantum systems.

Quantum computers harness the laws of quantum mechanics to solve problems that even the most advanced supercomputers or AI systems will never reach. Their impact will span energy, pharmaceuticals, finance, agriculture, transportation, materials, and other foundational industries.

Our architecture and approachisbased on silicon photonics. Byleveragingthe advanced semiconductor manufacturing industry-including partners like GlobalFoundries-we use the same high-volume processes that already produce billions of chips for telecom and consumer electronics. Photonics offers natural advantages for scale: photonsdon'tfeel heat, are immune to electromagnetic interference, and integrate with existing cryogenic cooling and standard fiber-optic infrastructure.

In 2024,PsiQuantumannounced government-funded projects to support the build-out of our first utility-scale quantum computers in Brisbane, Australia, and Chicago, Illinois. These initiatives reflect a growing recognition that quantum computing will be strategically and economically defining-and that now is the time to scale.

PsiQuantumalso develops the algorithms and software needed to make these systems commercially valuable. Our application, software, and industry teams work directly with leading Fortune 500 companies-including Lockheed Martin, Mercedes-Benz, Boehringer Ingelheim, and Mitsubishi Chemical-to prepare quantum solutions for real-world impact.

Quantum computing is not an extension of classical computing. Itrepresentsa fundamental shift-and a path to mastering challenges that cannot besolvedany other way. The potential is enormous, and we have a clearpathto make it real.

Come join us.

Job Summary:

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 daytoday operation of our monitoring stack-Grafana, Prometheus, Loki, and Tempo-crafting dashboards that surface golden signals and drive realtime insight. You'll codify reliability through SLIs/SLOs, automate runbooks in Python, and lead incident response to maintain worldclass uptime across both onprem and AWS environments.

Responsibilities:

• Define, implement, and iterate on Service Level Indicators & Service Level Objectives (SLIs/SLOs) and error budgets for critical services, with a focus on network reliability and data centre interconnects.

• Build and maintain Grafana dashboards that visualize golden signals (latency, traffic, errors, saturation), extending coverage to network telemetry such as packet loss, jitter, bandwidth utilization, and BGP/EVPN stability.

• Operate and tune the observability pipeline (Prometheus, Loki, Tempo) to ensure scalable, low-latency telemetry ingestion and alerting for networking as well as compute layers.

• Drive incident response: triage, mitigate, perform post-incident reviews, and implement preventive actions-particularly for network-related outages, congestion, or misconfigurations.

• Develop automation and self-service tooling in Python/Bash to streamline alerts, runbooks, and operational tasks, including network monitoring and diagnostics.

• Collaborate with Platform, Product, and Networking teams on capacity planning, performance testing, traffic engineering, and change management.

• Improve CI/CD health checks and release safety nets within GitLab, with attention to network dependencies in deployments.

• Contribute to Infrastructure as Code (Terraform, Ansible) for monitoring stack deployments and upgrades, including network observability tooling and configuration

Experience/Qualifications:

• Bachelor's Degree or higher in Computer Science, Engineering, or related technical field.

• 5+ years in an SRE, DevOps, or Production Engineering role supporting distributed systems in production.

• Hands-on expertise with observability tools: Grafana, Prometheus, Loki, Tempo (or equivalent).

• Proven track record designing dashboards and alerts around golden signals and USE/RED methodologies, extended to network utilization, saturation, and error metrics.

• Solid scripting/automation skills in Python and Bash; familiarity with GitLab CI pipelines.

• Operational experience with Kubernetes and containerized workloads.

• Strong working knowledge of AWS services, data centre networking fundamentals, routing protocols, load balancing, and network overlays (e.g., VXLAN/EVPN).

• Experience running incident response and writing actionable post-mortems, including for network-related events.

• Familiarity with Infrastructure as Code (Terraform, Ansible) and configuration management.

• Exposure to regulated environments, multi-region networking architectures, and hybrid on-prem/cloud topologies is a plus.

• Strong communication and collaboration skills; comfortable acting as a generalist across infrastructure, networking, application, and data layers.
