ABOUT SUBSTACK 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 — offering them creative freedom, ownership, and a direct connection to their audiences. We're growing fast. Millions of readers now come to Substack directly, and our app is the primary destination for our most engaged users. We're building the subscription network of the internet, and we're looking for a sharp, execution-oriented growth leader to build paid acquisition from the ground up. THE ROLE This is Substack's first dedicated paid acquisition hire. You'll own the strategy and execution of paid media across all channels — with an immediate focus on driving net-new, app-first user acquisition at efficient cost. You'll report to the Head of Growth and operate as a key member of the growth team at a pivotal moment: we have strong organic momentum, a proven gifting and referral flywheel within the existing user base, and now we're ready to scale growth beyond it. This is a high-ownership role. You'll manage budget, own channel strategy, run creative testing, instrument measurement infrastructure, and work cross-functionally with product, data, and creator partnerships to make it all work. You'll define what paid acquisition looks like at Substack including the frameworks, the channels, the metrics, and eventually the team. WHAT YOU'LL DO - Own paid acquisition end-to-end: strategy, execution, optimization, and reporting across Meta, Google UAC, YouTube, TikTok, podcast, and emerging channels - Design and run rigorous experiments to find efficient CAC on net-new users — people who have never been on Substack before - Build and manage our MMP infrastructure including deferred deep linking, in-app event
