Senior Test Infrastructure & Reliability Engineer, Photonics
PsiQuantum · Palo Alto, CA · Posted 1 day ago
Own the data pipeline and reliability systems that carry test results from a fleet of photonic quantum computer test stations into the central data platform, so failures surface immediately.
As an integral part of the team developing a photonic quantum computer, the Senior Test Infrastructure & Reliability Engineer will own the data pipeline and reliability of the systems that carry test results from our fleet of electro-optical test stations into our central data platform, making sure that when something breaks, we know about it immediately.
- 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.
Experience/Qualifications:
- BS in Computer Science, Electrical Engineering, or related field with 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 (e.g. 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.
- Zone 1 - Bay Area and NYC
Zone 1 $201,400 — $236,600 USD
Zone 2 $181,200 — $212,900 USD
