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.

• Move Fast: We act with speed and precision, breaking down big challenges into achievable steps.

• Focus: We complete one goal at a time with care, collaborating as a team to deliver features with precision.

• Balance: Sustained performance comes from rest and recovery. We ensure a healthy work-life balance to keep you at your best.

• Craftsmanship: Innovation through excellence. Every detail matters, and we take pride in mastering our craft.

• Minimal: Simplicity drives our innovation. We eliminate complexity through discipline and focus on what truly matters.

What We're Looking For

We are looking for an FP&A Manager to own the financial planning and analysis function at Lightning AI following our merger with Voltage Park. You will build and run the planning cadence for a combined business that spans a developer-first software platform and a large-scale GPU cloud, translating a complex P&L into the clearest possible picture of performance, unit economics, and capital efficiency for leadership, the board, and our investors.

You will be the financial backbone behind decisions that span GPU capacity and CapEx, software ARR growth, merger integration, and long-range planning. You will own the model, own the forecast, and own the narrative behind the numbers. You will work directly with senior executives across Infrastructure, Sales, Product, Engineering, Marketing, and Accounting.

This role is ideal for someone who wants to graduate from building models to shaping how an AI cloud runs its business and who finds it energizing to bring order to a fast-moving, post-merger environment.

This is a hybrid role based in either New York City or San Francisco with in-office requirements of 2 days per week. The salary range for this role is $185,000–$210,000.

What You'll Do

• Own the company-wide operating model, including P&L, balance sheet, and cash flow, built on a driver-based framework that reflects both software and infrastructure dynamics
• Lead annual planning, forecasting, and long-range planning, coordinating inputs from every function and delivering a single source of truth
• Run the monthly and quarterly close-to-report cycle: variance analysis, KPI commentary, and executive-ready narratives on what changed and why
• Prepare board decks, investor updates, and lender reporting packages
• Lead post-merger financial integration between Lightning AI and Voltage Park, including intercompany reporting, addback schedules, synergy tracking, and more
• Contribute to GPU financing, debt, and equity fundraising workstreams, including model support, data room preparation, and lender and investor communications
• Support M&A diligence and integration modeling as opportunities arise
• Own and evolve the FP&A tech stack (NetSuite, planning tools, BI) to improve data accuracy, close speed, and self-service reporting for business partners
• Design reporting automations and dashboards that free the team from manual refresh work and scale with the business
• Build the FP&A team as Lightning AI scales

What You'll Need

• Bachelor's degree in Finance, Accounting, Economics, or a related field
• 7+ years of progressive experience in FP&A, strategic finance, investment banking, private equity, or corporate development
• Experience at a cloud infrastructure companies and/or AI startups
• Expert financial modeling skills: you can build a three-statement, driver-based model from scratch and defend every assumption
• Strong command of SaaS and consumption metrics alongside infrastructure economics
• Fluency with NetSuite and modern planning/BI tooling
• Excellent written and verbal communication
• Track record of cross-functional partnership
• Bias to action, high ownership, and comfort operating in a startup environment where priorities shift
• Experience with post-merger integration, intercompany reporting, or purchase accounting
• Exposure to debt financing, asset-backed lending, or GPU-as-collateral structures
• CPA, CFA, or MBA
