Staff Software Engineer, Observability/Site Reliability

The Observability team builds and runs the telemetry platform that lets PsiQuantum see how its quantum computing systems, and the infrastructure behind them, are behaving. We collect metrics, logs, and traces from on-premises Kubernetes clusters, cloud infrastructure, and the custom hardware that makes up a photonic quantum computer, including control electronics and cryostats. Engineering, operations, hardware, and research teams rely on this data to run the machine, catch problems early, and work out what went wrong when something fails.

We are looking for a Staff Software Engineer to join the Observability team. You will wire up OpenTelemetry instrumentation and collection, run and scale Prometheus and Grafana, and turn raw signals into dashboards and alerts that people trust. A large part of the job is working with hardware teams: deciding what their devices should report, and getting that data off the device and into the platform reliably.

This is a hands-on role with Staff-level scope. You will own major parts of the observability stack from design through operation, share the team's on-call rotation, and set the conventions other teams follow when they instrument their own systems. You will combine hands-on delivery with technical leadership, sound judgment under ambiguity, and a strong bias toward simple, maintainable systems.
