Senior Legal Counsel

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.

We are looking for a Senior Counsel to join our Legal team at an inflection point. Lightning AI is on a strong growth trajectory—backed by Coatue, Index Ventures, Bain Capital Ventures, and Firstminute—and the legal function is scaling with it. You will be joining a small, high-performing team with solid infrastructure already in place, and stepping into a role with real ownership: primary responsibility for the corporate legal matters that sit at the heart of how we grow, finance the business, and transact. As AI regulation and governance become increasingly central to how technology companies operate, you will also be on the front lines of those emerging issues—advising leadership as the legal landscape around AI infrastructure continues to evolve. You will join the Legal Team and report directly to the VP of Legal.

This is a hybrid role based in our New York City or San Francisco office with in-office requirements of 2 days per week.
