Head of Strategic FP&A; Financial Planning & Analysis

Substack is building a new economic engine for culture, giving the brightest, most interesting, and most creative people on the internet the power of their own publishing platform. Substack empowers independent writers, artists, videographers, podcasters, and creators of all types to create, share, and make a living off their work through subscriptions, while offering them creative freedom, ownership, and a direct connection to their audiences.

By leveraging modern technology, automation, and AI tools, you and your team will bypass traditional spreadsheet busywork to operate as an ultra-high-leverage "tiger team"—one that asks the sharpest strategic questions, uncovers crucial business drivers, and rapidly executes on the answers alongside the CEO, CFO, and executive team.

At Substack, you will hold a front-row seat—and a hands-on steering wheel—in shaping the business model behind the future of independent media. You’ll work directly alongside our founders and executive team to build a durable, generation-defining company.
