Job summary

PsiQuantum is building photonic quantum computers and this role sits within the team delivering data reliability for test stations. As Senior Test Infrastructure & Reliability Engineer you will own the data pipeline from test stations to the central data platform and ensure immediate visibility when issues occur.

You will build fleet-wide observability, dashboards and logs, define guardrails for early regression detection, and collaborate with data platform and test software engineers to close

Qualifications

• BS in Computer Science, Electrical Engineering, or related field; 5+ years of relevant experience (MS with 3+ years, or PhD with 0-2 years).
• Experience building and operating reliable distributed systems or data pipelines.
• Strong Python skills, comfortable with async and multi-process/service architectures.
• Experience with observability stacks (Grafana, Loki) and designing effective alerts.
• SQL proficiency for ad hoc investigation against production data.
• Track record of root-causing distributed-system issues from fleet-scale evidence.
• Experience in lab, manufacturing, or hardware test environments.
• On-call or incident-response experience.

Responsibilities

• Own the data pipeline connecting test stations to the central data platform: measurement uploaders, run creation, and run-to-test-request linking.
• Build fleet-wide observability: dashboards, log pipelines, and metrics for station and data-pipeline health.
• Define and maintain alerting/guardrails that catch regressions early (upload latency, stale heartbeats, clock drift) before they become data-loss incidents.
• Harden shared infrastructure (uploader processes, heartbeat reporting, notification integrations) against common distributed-systems failure modes.
• Investigate and root-cause fleet-wide reliability incidents using logs, timestamps, and API data, distinguishing station-side, server-side, and network/clock causes.
• Partner with the data platform team and test software engineers to close gaps between station software and the central system of record.
