Lightning AI is the company behind PyTorch Lightning. Founded in 2019, we build an end‑to‑end platform for developing, training, and deploying AI systems—designed to take ideas from research to production with less friction.

Through our merger with Voltage Park, a neocloud and AI Factory, Lightning AI combines developer‑first software with cost‑efficient, large‑scale compute. Teams get the tools they need for experimentation, training, and production inference, with security, observability, and control built in.

We serve solo researchers, startups, and large enterprises. Lightning AI operates globally with offices in New York City, San Francisco, Seattle, and London, and is backed by Coatue, Index Ventures, Bain Capital Ventures, and First minute.

Lightning AI is seeking an Observability Infrastructure Engineer to join our Infrastructure Engineering team.

In this role, you will own and evolve observability systems across large‑scale, GPU‑enabled bare‑metal infrastructure. You’ll operate at the intersection of infrastructure, data, and product, building platforms for metrics, logs, traces, and alerting that power both internal operations and customer‑facing visibility.

You will play a key role in productizing observability, enabling scalable, multi‑tenant monitoring experiences while keeping pace with rapid infrastructure buildouts. This includes designing telemetry pipelines, improving signal quality, and delivering actionable insights that ensure reliability and transparency across our platform.

We’re flexible on location for this team. This role can work hybrid out of one of our U.S.‑based hubs (Seattle, NYC, or SF) or fully remote within the U.S., with occasional company and team offsites. We are not able to provide visa sponsorship for this position at this time.

• Own and evolve a scalable observability platform spanning metrics, logs, traces, and events
• Drive the productization of observability capabilities for both internal teams and external customers
• Design multi‑tenant observability systems with scoped access, RBAC, and customer‑facing visibility
• Continuously improve observability systems to keep pace with rapid infrastructure buildouts

• Design and operate telemetry pipelines ingesting data from GPUs, CPUs, networking (Ethernet & Infini Band), containers, APIs, and BMC/Redfish
• Build systems to correlate signals across infrastructure layers to enable faster debugging and root cause analysis
• Implement streaming and real‑time data pipelines using tools such as Kafka, OTEL, Promtail, or similar

• Design and implement noise‑resistant alerting systems to improve signal quality and reduce operational load
• Create dashboards and alerting for Infra Ops, Engineering, and Customer Success teams
• Build automated insights and enable proactive detection, forecasting, and system health visibility at scale
• Contribute to broader infrastructure engineering projects beyond observability
• Partner with infrastructure and platform teams to embed observability into core systems and workflows
• Support large‑scale, distributed systems across compute, networking, and storage environments

• Work closely with customer‑facing teams to deliver external observability experiences
• Collaborate with engineering, operations, and support teams to improve system transparency and reliability
