Infrastructure Engineer (Observability)

Who We Are 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 Firstminute. The Way We Work The people who thrive here are builders who move fast, communicate openly, take ownership, and continuously improve themselves, their teams, and our company. Here's what that looks like in practice: Move with Urgency: We move quickly, make thoughtful decisions, and keep momentum. We value action over perfection and learn by shipping. Take Ownership: We own outcomes, not just our individual work. We make decisions that move the company forward and follow through. Communicate Openly: We communicate directly, seek to understand, and create clarity for others. Honest conversations help us move faster together. Build Great Teams: We lead by example, empower others, and create healthy teams where people can do their best work. Raise the Bar: We're always improving ourselves. We learn from feedback, consistently challenge ourselves to grow, and focus on the work that matters most. Think Long-Term: We design for what's next. We create scalable systems, simplify complexity, and use AI and automation to amplify our impact.   What We’re Looking For 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. This role is based in one of our hubs (NYC, SF, Seattle, or London), with a minimum of 2 in-office days per week and occasional team and company offsites. We are not able to provide visa sponsorship for this position at this time. What You’ll Do Observability Platform & Productization 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 Telemetry & Data Pipelines Design and operate telemetry pipelines ingesting data from GPUs, CPUs, networking (Ethernet & InfiniBand), 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 Alerting, Reliability & Insights Design and implement noise-resistant alerting systems to improve signal quality and reduce operational load Create dashboards and alerting for InfraOps, Engineering, and Customer Success teams Build automated insights and enable proactive detection, forecasting, and system health visibility at scale Systems & Infrastructure Engineering 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 Cross-Functional Collaboration Work closely with customer-facing teams to deliver external observability experiences Collaborate with engineering, operations, and support teams to improve system transparency and reliability Help define best practices for observability across the organization What You’ll Need Required Qualifications 5+ years of experience in infrastructure engineering, SRE, or observability-focused roles Strong experience with monitoring systems such as Prometheus, Grafana, ELK, or VictoriaMetrics Experience building and operating observability platforms at scale Proficiency in Python, Go, or bash for automation and data integration Familiarity with containerized environments and Kubernetes observability Experience with streaming telemetry pipelines (Kafka, OTEL, Promtail, or equivalent) Experience with multi-tenant monitoring architectures Strong written and verbal communication skills Ideal Experience Experience with GPU observability, particularly NVIDIA DCGM Experience monitoring large-scale GPU or HPC clusters Familiarity with InfiniBand fabric observability Experience building customer-facing or productized infrastructure systems Experience with correlation engines, RCA workflows, or predictive alerting systems Broad exposure to infrastructure domains including networking, storage, and provisioning Compensation We are committed to offering competitive compensation that reflects the value each team member brings to our mission. Final offers are based on factors such as experience, skills, geographic location, and role expectatio
