Founding GTM Engineer

About the role

You build the systems that run Hearth's go-to-market: the whole engine, one motion at a time. You're a business builder, not an engineer who needs a brief. You find the lever that moves the number and ship the system that pulls it, fast: a sales lead flags a broken handoff on Monday, the fix is live on the floor by Wednesday.

Opportunity

Hearth is the AI growth system for local home-improvement contractors. Over 50% of these businesses go under without software like Hearth, and when you ship a system that works, a roofer stops losing 40% of his inbound calls and gets home for dinner. The loop between your work and someone's livelihood is short. You're the first hire on our GTM engineering function, and the timing is the point: we're launching new products, and each one needs its own go-to-market built around it: the routing, the outreach, the tooling, the measurement.

What You'll Build

• Move the numbers, and build whatever moves them. Sometimes that's a routing change, sometimes a new scoring layer, sometimes an AI agent that takes a rep's busywork.
• The thread through all of it: decide where the leverage is, then build it.
• We've started on inbound conversion (routing and next-best-action on our existing lead-scoring model), but it needs scale and a real rethink.
• From there the surface is wide: the outbound motion, marketing automation and testing, the measurement model that points spend at what actually converts, and the repfacing AI that handles research and follow-up so reps sell.
• Underneath it is one backbone, the data and integrations that connect our CRM, enrichment, and scoring, so the motions run on one system instead of four bolted together.
• We already run AI in production today (lead scoring, Clay workflows); your job is to push it deeper across every motion.

Who You Are

• Think in revenue, not features. Look at a funnel and know which fix is worth the most.
• Ship in days, not quarters. A week spent planning instead of building feels like a loss.
• Grow as the tools grow. What was prompts and personas last year is Claude Code and full apps now; you reinvent your workflow the moment something better lands.
• Get things done through people. Co-drive with the sales and marketing leaders and earn the trust to change how they work.
