Head of Growth Marketing

Head Of Growth Marketing

We're hiring a Head of Growth Marketing to accelerate Fathom's next stage of growth. In this role, you'll build, test, and scale strategies that drive acquisition, product adoption, and virality. You'll own growth experiments across community, paid, organic, and product-led funnels -- combining creativity with analytical rigor.

You'll report to our VP of Marketing and partner closely with Product, Data, Ops, Sales, and our leadership team. This is an ideal role for someone who thrives in fast-moving startup environments, loves blending strategy with execution, and is obsessed with turning ideas into measurable impact. The rate of iteration in AI excites you, and has fundamentally shaped how you approach your work and problem solving.

You consider yourself a player-coach, and know that the best coaches still get their hands dirty. For now, you'll operate lean with strong internal partners and external resources.

What you'll do:

• Take ownership of our new user acquisition target, driving the strategy across paid marketing, SEO & GEO, and more.
• Design, run, and scale growth experiments across the funnel -- from acquisition channels to influencing in-product activation.
• Build, collaborate, and optimize multi-channel campaigns (paid, organic, lifecycle, referral, partnerships) that drive signups and revenue. Manage agencies to support execution of many campaigns.
• Partner with Product and Data to design in-product growth loops, onboarding flows, and conversion journeys.
• Define, measure, and report on growth KPIs -- owning dashboards and analysis to surface insights and drive decisions.
• Research and test new channels, tactics, and tools to keep us ahead of the curve.
• Build scalable playbooks so wins can be repeated and expanded scalably, while aligning with our leadership team on budgeting.

Who we think will thrive (aka requirements):

• 5+ years in self-serve subscription growth, demand generation, or performance marketing in B2B SaaS (ideally PLG).
• Proven track record of designing and running growth experiments that deliver measurable results.
• Strong analytical skills -- fluent in data analysis, funnel metrics, and growth KPIs.
• Hands-on experience with analytics and experimentation tools (working with WebFlow, HubSpot, Amplitude, Hex, GA4, etc.).
• Creative and scrappy: you can ideate, launch, and measure campaigns quickly.
• Comfortable working cross-functionally with Product, Data, and Sales.
• Bias toward action, resourceful, and energized by fast-paced startup environments.

About our hiring process:

• You'll first meet with the VP of Marketing, then several members of the team. We'll wrap with a very timeboxed exercise.
• We'll ask you to walk us through past growth experiments and outcomes. We're excited to see how you think, test, and measure impact.
• We believe in honest transparency. Ask us anything about the role, company, day-to-day expectations, outcomes, and more.
• We move fast: expect a 2–3 week process from start to finish.
