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 Senior 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.

What you'll do

• Experiment across channels and tactics to drive user acquisition, including SEO, content marketing, social media, and new formats worth testing.

• Use data analytics and user insights to find optimization opportunities across the funnel, design rigorous experiments, and measure real impact.

• Manage performance marketing across paid channels, partnering on creative testing, audience development, and ROI optimization.

• Scale and mange affiliate and creator program from the ground up.

• 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

• 3+ years in growth marketing with a focus on user acquisition, ideally at a startup or high-growth product company where you built things from scratch.

• Strong analytical skills, with the ability to move from data to decision quickly — SQL fluency is a real plus.

• Deep hands-on experience with owned and earned media: you know how to scale SEO, content, and social, not just manage them.

• A self-starter mindset: you're comfortable with ambiguity, move fast, and don't wait for a perfect brief to get started.

• Experience as a founder or in a prosumer or consumer product environment (Nice to have)

Compensation range:

The base salary for this full-time position, which spans multiple internal levels depending on qualifications, ranges between $150K - $250K plus benefits & equity.
