Growth Marketing Manager

About the role

==================

Gamma has grown to over 100 million users, and a significant part of that story is organic. Now we're building the engine that accelerates what's already working. As our Growth Manager, you'll own top-of-funnel growth: finding the channels, experiments, and levers that bring the right users to Gamma and turn them into active creators.

This is a hands-on role. You'll run experiments across SEO, content, social, and emerging channels, use data to figure out what's actually moving the needle, and build the infrastructure to do more of it. You'll work closely with product, engineering, and design to identify high-impact growth opportunities and turn them into shipped initiatives. If you're the kind of person who builds the playbook rather than follows one, and who gets genuinely excited about finding growth in unexpected places, this role is for you.

Our team has a strong in-office culture and works in person 4–5 days per week in San Francisco. We love working together to stay creative and connected, with flexibility to work from home when focus matters most.

• Drive site-to-signup conversion optimization, turning traffic into activated users
• Collaborate with product, engineering, and design to identify and prioritize growth-specific improvements that compound at scale

What you'll bring
