This posting About this job ABOUT PROBOOK Probook is the AI Operating System for the home services industry, transforming how plumbing, HVAC, and electrical businesses operate. Our impact is real. Dispatching the right technician to the right job can mean the difference between a $300 "band-aid" fix and a $20,000 system replacement. By automating previously high-touch workflows around-the-clock, Probook ensures a consistent customer experience without the need for 24/7 live staffing. We unify our customers' processes into a single, scalable platform, giving businesses one place to run their entire dispatch operation. The Opportunity This isn't a role where you'll optimize existing features—you'll define and ship the product capabilities that unlock our next phase of hypergrowth. The products you build in the next 12 months will serve tens of thousands of users and process hundreds of millions in transactions. You'll own entire product surfaces end-to-end, set technical and product quality standards for the engineering org, and work directly with leadership to translate business strategy into shipped product. Every feature you ship will directly impact our ability to capture market share at speed. You'll see your work drive millions in ARR in real-time, validated by direct customer feedback from our in-person onboarding process.
