Probook is the AI dispatcher for the home services industry, transforming how plumbing, HVAC, and electrical businesses operate. Our impact is real.

We unify these processes into a single, scalable platform, giving businesses one place to run their entire dispatch operation.The OpportunityThis is not a role where you'll work on incremental features—you'll architect and ship the fundamental capabilities that define our platform.Every feature you build will directly impact ARR.
