Global Tax Lead

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 Global Tax Lead to own and scale Lightning’s corporate tax compliance function as the company grows. You will be responsible for managing income tax compliance, tax accounting support, forecasting, risk mitigation, and tax process improvements across the business. This role will partner closely with Finance, Accounting, FP&A, Legal, and external advisors to ensure accurate filings, strong controls, and scalable tax operations.

This is a high-impact role for someone who combines deep technical tax expertise with an operational mindset. You will help build the systems, processes, documentation, and controls needed to support a fast-growing AI infrastructure company operating in a complex and evolving tax environment. The tax scope is broad, leadership visibility is high, and the work directly supports financial accuracy, compliance, risk management, and long-term business scalability.
