Job summary

PsiQuantum in Palo Alto, CA (remote) seeks a Senior Test Infrastructure & Reliability Engineer, Photonics, to own the data pipeline and ensure reliability of test systems feeding the central data platform as part of the Photonics Integration team.

You will build fleet-wide observability, define alerts, and work with test software and data platform teams to prevent data-loss incidents while improving hardware test environments.

• Build fleet-wide observability: dashboards, log pipelines, and metrics for station and data-pipeline health.
• Define and maintain alerting/guardrails that catch regressions early before data-loss incidents.
• Harden shared infrastructure against common distributed-systems failure modes.
