Senior Accountant - General Ledger

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.

We are looking for a Senior Accountant, General Ledger to support the general ledger close across our legal entities, including the balance sheet, the reconciliations behind it, and the reporting package that comes out of it, and to help rebuild how that close runs.

This is the record-to-report seat. Our Accounting Manager, Revenue Operations owns revenue and AR; our Senior Accountant, Accounts Payable & Procure-to-Pay owns the payables cycle. You will support the rest of the balance sheet such as cash reconciliation, intercompany, payroll accrual, prepaids, fixed assets, leases, and the monthly financial statements and flux analysis that tie it all together.

The transformation half of the title is not decoration. You will close the books each month and help redesign the process you just ran, migrating it into NetSuite, replacing manual workarounds with controls, and documenting it so it no longer depends on any one person.

You will be joining the Finance Team and report to the Director of Corporate Accounting. This is a hybrid role based in our San Francisco office with in-office
