About Lightning AI
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.
What We’re Looking For
We are looking to hire Platform Support Engineers to join our EMEA Customer Experience team, supporting ML engineers running large‑scale training and inference workloads across cloud infrastructure, Kubernetes, and GPU platforms in production environments. This role is not a ticket router or traditional support engineer. You are a technical partner to ML teams—helping diagnose failures, improve reliability, and guide customers through complex distributed systems problems. The problems range from Kubernetes scheduling and GPU orchestration to distributed PyTorch failures, inference latency, networking bottlenecks, storage performance, and platform reliability. You’ll gain exposure to a wide variety of real world AI workloads across industries and help shape the infrastructure powering the next generation of ML applications.
EMEA Shifts
- We are currently hiring for two EMEA shifts (9AM–7PM CET/CEST):
- Sunday–Wednesday
- Saturday–Tuesday or Thursday–Sunday
Location: London office (hybrid). In‑office requirement of at least 2 days per week and occasional team/off‑site events. We are not able to provide visa sponsorship at this time.
What You’ll Do
- Work Directly With ML Engineers
Partner directly with customer engineering teams running training and inference workloads in production. Help customers diagnose and resolve complex distributed systems and ML infrastructure issues. Act as a technical advisor during high‑impact incidents and platform degradation events. Translate infrastructure‑level issues into actionable guidance for ML engineers. Build credibility with customers through strong technical reasoning and clear communication.
- Debug ML Infrastructure & Distributed Workloads
Investigate failures involving distributed training, Kubernetes orchestration, GPU allocation, networking, and storage systems. Troubleshoot PyTorch, CUDA, NCCL, and inference serving related issues. Analyze logs, metrics, traces, and system behavior to isolate root causes. Debug containerized workloads running across Kubernetes and bare‑metal GPU environments. Support customers scaling workloads across multi‑node GPU systems. Diagnose performance bottlenecks involving compute, memory, networking, or storage.
- Improve Reliability & Platform Operations
Identify recurring patterns across customer issues and drive long‑term reliability improvements. Contribute to post‑incident reviews and operational improvements. Build internal tooling, automation, documentation, and runbooks. Partner closely with infrastructure, networking, and platform engineering teams. Help improve observability, operational visibility, and troubleshooting workflows. Improve the customer experience through better processes and technical guidance.
What This Role Is Not
- This is not a traditional help desk or ticket routing support role.
- This is not purely customer success or account management.
- This is not a backend engineering role.
- This is not a passive escalation position.
What You’ll Need
Required Qualifications- Infrastructure & Systems
Strong software engineering and systems troubleshooting background. Experience with Kubernetes and containerized environments. Linux systems knowledge, including networking, storage, process management, and performance tuning. Experience with cloud infrastructure and distributed systems. Experience with observability and debugging tools such as Prometheus, Grafana, or OpenTelemetry.
- ML Infrastructure Experience
Hands‑on experience operating machine learning workloads in production or research environments. Experience with distributed ML systems and tooling such as PyTorch, CUDA, or NCCL. Familiarity with GPU infrastructure and orchestration. Experience troubleshooting performance, reliability, or scaling issues in ML infrastructure. Understanding of the operational challenges involved in running ML systems at scale.
- Collaboration
Strong communication skills and ability to work directly with highly technical customers and engineering teams. Comfortable operating in fast‑moving, highly ambiguous environments. Enjoys solving complex technical problems collaboratively.
Nice‑to‑Haves
- Experience with large‑scale model training or distributed inference systems.
- Familiarity with Ray, Kubeflow, Slurm, or similar distributed scheduling platforms.
- Experience with InfiniBand, RDMA, or high‑performance networking.
- Experience operating bare‑metal infrastructure.
- Familiarity with storage systems commonly used in ML environments.
- Experience working at an AI infrastructure, cloud, MLOps, or developer tooling company.
- Contributions to platform engineering, developer infrastructure, or operational tooling projects.
- Experience writing automation, tooling, or scripts in Python or similar languages.
