Product Manager - Growth

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 come to Substack directly every month, and our app is the primary destination for our most engaged users. We're looking for a rare hybrid — someone who thinks like a product manager, works closely with engineers, and has deep expertise in the organic growth levers that compound over time: SEO, ASO, and new user onboarding.

The Role

This is a new role on the Growth team, focused on growing the entire Substack ecosystem. You'll own product-led growth across both sides of our network: helping more creators successfully launch and grow, helping more readers discover and engage with great work, and converting more of that engagement into paid subscriptions.

You'll report to the Head of Growth and work primarily with the Activation engineering team, in close partnership with Data, Growth Marketing, Creator Experience, and other product teams. Your scope will span new user app acquisition, reader onboarding and activation, payer funnels, and creator onboarding and activation. You'll identify the highest-leverage opportunities across these connected journeys and turn them into durable growth loops that strengthen the ecosystem as a whole.

This is a product management role for someone who can move fluidly between strategy and execution. You'll diagnose funnel constraints, build a clear roadmap, write crisp PRDs, partner closely with engineers and designers, and run experiments from idea through measurement. You should be equally comfortable improving an individual conversion step and reasoning about how creators, readers, and payers reinforce one another across the network.

What You'll Do

Consumer Growth

Build and improve product loops that bring new readers into the Substack app through sharing, referrals, creator distribution, content discovery, and other scalable channels

Own the consumer journey from first touch through app install, account creation, onboarding, engagement, and early retention

Improve payer funnels, helping more engaged readers discover publications they value, understand the benefits of subscribing, and become long-term paid subscribers

Partner with Growth Marketing, Data, Design, and Engineering on acquisition strategy, attribution, experimentation, and campaign-to-product handoffs

Creator Growth

Own the creator journey from initial intent through publication setup, launch, onboarding, activation, and early retention

Identify the behaviors that predict creator success and build experiences that help more creators reach those milestones quickly

Improve creator growth loops across audience import, sharing and referrals, reader conversion, paid offering setup, and pathways from publishing to earning

Partner across Creator Experience, Partnerships, Growth Marketing, Data, Design, and Engineering to diagnose funnel constraints, run experiments, and build a holistic creator growth roadmap

What We're Looking For

An ambitious, founder-type product manager with 5–8 years of experience

Comfort with ambiguity: you can find structure in an unclear problem, form a strong point of view, and move from strategy to execution without waiting for perfect information

The curiosity and analytical depth to go very deep on a problem, understand its underlying mechanics, and keep pushing until you've found the highest-leverage solution

Experience working on multi-sided marketplaces, networks, or ecosystems, with a strong intuition for how to create value for and balance the needs of different participants

Familiarity with Substack, alignment with our mission, and a thoughtful perspective on media, publishing, and the creator economy
