Engineer, IT ​/ Software Sales

Hearth is the AI growth system for local home improvement small businesses. We build revenue-critical software for home improvement contractors — the roofers, HVAC techs, and builders who keep America running.

Our platform helps real business owners win more jobs, protect profit margins, and manage homeowner relationships professionally so they can build generational companies for their families and communities.

We are now building the next layer: a personal AI employee for every small business in the trades focused on autonomously generating sales for America’s home improvement pros. An assistant who answers every call 24/7, qualifies leads, books appointments, follows up on quotes and estimates, and helps small business owners go from missing half of their business to capturing all of it.

With 15,000+ paying customers, default profitability, and backing from some of the world’s best investors (Founder’s Fund, 8VC, Human Capital, etc.), Hearth is focused on bringing AI to the trades.

You own how Hearth acquires customers, and you build the system that does it.

Hearth has already built the AI‑first part. We have an AI acquisition tool running in production today that scores and values inbound demand and feeds our bidding. It works.

Your job is to run it and make it great. You will work hands‑on with our CEO, who built it, as it scales, and you will take it over fully. That means owning whether it is right, whether the people betting budget on it can trust what it tells them, and how much stronger it is each quarter than the quarter before.

Then there is everything around it. The funnel the tool sits inside, the measurement that proves what each stage did, the automation connecting the ad platforms to the sales floor, and the ideas and content that grow the top of it. All of that is still to be built, and it is also yours.

Make the engine great first. The rest gets easier once it is.

• Increase qualified contractor lead volume
• Scale spend while preserving ROAS
• Build a repeatable paid acquisition engine

• The AI acquisition engine. You run it every day, and you make it better. You are accountable for it being accurate, for everyone downstream being able to trust what it says, and for it getting materially stronger under you.
• Customer acquisition cost. You own the number. You move it with code and bid logic, not with a bigger budget.
• Lead volume at a CAC that holds. Scaling spend is easy. Scaling spend without breaking unit economics is the job.
• The funnel. You build it end to end. Ad, landing page, lead, handoff to sales. Every stage is yours to design, instrument, and improve, and no stage belongs to someone else.
• The measurement. You build the way we know what worked. Attribution across stages, conversion tracking that survives contact with reality, daily reporting in SQL and Python that people actually open. If we cannot see what a dollar did, that is yours to solve.
• How we grow. Content, offers, creative, audiences, new channels. You bring the ideas for reaching more contractors, you design the tests that resolve them, and you kill what loses.
• The acquisition stack. Feed automation, ad scripts, bid strategy, pixels, the pipelines carrying data from the ad platforms into the CRM and back out. You build it, you run it, you are on the hook when it is wrong.

One question sits behind every interview:
did you build the system, or did you manage the people and agencies who built it?

• Deep hands‑on Google and Meta. Not oversight of them. You have run real budget in both accounts yourself, and you know where each platform tells you what you want to hear.
• You build AI‑first, and you know the plumbing. You have wired models into real…
