Lightning AI is seeking an experienced Senior Infrastructure Operations Engineer to help scale and operate its next-generation AI infrastructure platform. The InfraOps team sits at the center of reliability, automation, and operational scale for GPU infrastructure, owning break/fix operations, incident response, customer provisioning, observability, and automation systems that keep complex infrastructure running efficiently.
In this role, you will work hands-on with large-scale GPU environments, Linux systems, bare metal infrastructure, provisioning workflows, and platform reliability. You will partner closely with Infrastructure Engineering, Network Operations, and Software Platform teams to troubleshoot issues, improve operational efficiency, and build automation that reduces manual toil. You will design, build, and roll out new platforms and patterns to minimize incidents and enable customer-facing and internal features. You will deploy updates and improvements to support both Lightning AI's internal and end-customer use cases, collaborate across teams, and participate in an evenly distributed on-call rotation (primary/secondary pattern).
Lightning AI is the company behind PyTorch Lightning, founded in 2019. Through its merger with Voltage Park (a neocloud and AI Factory), Lightning AI combines developer-first software with cost-efficient, large-scale compute. The company serves solo researchers, startups, and large enterprises globally, with offices in New York City, San Francisco, Seattle, and London. It is backed by Coatue, Index Ventures, Bain Capital Ventures, and Firstminute.
The role may be fully remote within the UK or hybrid out of the London office hub, with occasional team and company offsites. Work visa sponsorship is not available for this position.
