Rebar develops a vertical AI operating system that automates estimating and quoting for HVAC, electrical, and plumbing contractors.
ABOUT REBAR Rebar is building the next-generation operating system for commercial HVAC, electrical, and plumbing suppliers and subcontractors. Over the past year, our V1 quoting product has scaled to thousands of quotes completed weekly, doubled revenue six weeks into 2026, and gained adoption across many of the top suppliers in North America. Fresh off a $14M Series A backed by leading construction tech investors, we're entering our next phase of growth, and we are looking for a Client Success Manager to support our Success motion. You’ll work directly with the Client Success (CS), Product, and Sales teams to support clients and build the systems that will define Rebar’s client experience. We’re transforming the $250B HVAC industry with AI-native software—an industry still largely untouched by modern tools. This is your chance to get in early. THE ROLE: CLIENT SUCCESS MANAGER (POST-IMPLEMENTATION & GROWTH) This is not a traditional “CSM” role. Our Implementation team owns onboarding. We’re looking for someone with industry experience to take full ownership of the client relationship post–handoff—driving adoption, solving day-to-day problems, and ensuring clients get real value from Rebar in their workflows. You’ll be part operator, part problem-solver, part product feedback loop. You’ll work directly with clients, the CS team, Sales, Product, and Engineering to make sure our software works in the real world, and improves continuously. This role is high intensity, high ownership, and high upside. If you’re looking for a highly structured, low-pressure CS role, this is not it.
