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

We are looking for a Treasury Lead to own and scale key treasury accounting, reporting, and control processes as Lightning grows. You will play a critical role in supporting treasury-related activities across financing arrangements, capital investments, vendor obligations, cash management, hedging, and financial reporting. This role will partner closely with Finance, Accounting, Legal, Tax, Infrastructure Operations, Accounts Payable, and external auditors to ensure accurate reporting, strong controls, and scalable treasury processes.

This is a high-impact role for someone who combines strong technical accounting knowledge with an operational mindset. You will help evaluate complex financing structures, support accounting conclusions, maintain documentation, and strengthen the control environment around treasury activities. The treasury scope is deep, leadership visibility is high, and the work directly supports capital allocation, infrastructure growth, audit readiness, and financial accuracy.

This is a hybrid role based in San Francisco with in-office requirements of 2 days per week.
