Growth Engineer

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.

We are hiring a Growth Engineer. You will own Hearth's paid acquisition function and work directly with the CEO to scale customer acquisition.

We need someone who is an expert in running ads on Facebook and Google - someone who can own that process end-to-end. Not a generalist. Not someone good at referral marketing or brand campaigns. Someone who lives inside Ads Manager, knows what levers to pull and can scale contractor acquisition through paid channels. You will be directly accountable for lead volume, cost per lead, and CAC.

You will own every dollar spent on paid channels - and every lead those dollars produce.

What Success Looks Like:

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

What You'll Do:

• Own and operate Facebook Ads and Google Ads end-to-end — campaign strategy, audience targeting, bid management, creative testing, budget allocation, and daily optimization
• Build and scale programmatic display and native campaigns across additional channels (The Trade Desk, DV360, You Tube, Reddit, or wherever contractors spend time)
• Drive lead generation for Hearth's contractor acquisition — every campaign you run feeds directly into the sales pipeline
• Manage meaningful paid budgets with full P&L accountability — you forecast spend, track CAC and ROAS in real-time, and reallocate budget based on what's working
• Build and optimize landing pages, conversion funnels, and lead capture flows — from ad click to qualified lead
• Run rigorous A/B tests on creative, copy, audiences, landing pages, and bidding strategies — every dollar is an experiment
• Set up and maintain conversion tracking, pixel implementation, and attribution infrastructure — you'll know exactly which campaigns drive revenue, not just clicks
• Build automated reporting dashboards so performance is visible daily, not monthly
• Leverage AI tools to scale creative production, audience modeling, and bid optimization — you'll use AI to outperform competitors who do this manually

What We're Looking For:

• Paid acquisition specialist. 5–10 years running Facebook Ads and Google Ads ’ve managed $500K+ monthly paid budgets and can optimize campaigns in your sleep. You know the platforms at an expert level — not just boosted posts and broad match keywords.
• Performance obsessed. You think in CPL, CAC, ROAS, and LTV — not impressions and reach. Every campaign has a target and you hit it or you know why you didn’t.
• Hands‑on operator. You build campaigns yourself. You're in Ads Manager daily. You write ad copy, test creative, adjust bids, and troubleshoot tracking issues. You don't manage agencies — you are the agency.
• Data‑driven. You can pull your own data, build reports, and make budget decisions based on numbers. Comfortable with SQL, Excel/Sheets, and BI tools. You set up attribution and trust your own tracking.
• Creative tester. You understand that creative is the biggest lever in paid acquisition. You test dozens of variations, know what hooks work for different audiences, and can brief a designer or write copy yourself.
• Technical enough. You can implement pixels, set up conversion events, troubleshoot…
