About Able Able is the AI front office for Wholesale Plumbing, HVAC, and Electrical Suppliers. We're automating the soul-crushing manual work that buries inside sales teams - starting with fixture quoting. The Wholesale Supply market is a $350B+ market running on spreadsheets and tribal knowledge. We're building the infrastructure to change that. About the Role Founding Engineer, with a focus on shipping Agents. You'll spec features, debug weird edge cases, scale infrastructure and help us figure out what to build next based on what customers actually need. We're not looking for someone who needs a roadmap handed to them. We're looking for somebody who wants to help build the roadmap. If you see a problem, you fix it. If you don't know something, you learn it.

You don't need to be an infra specialist but you shouldn't be scared of it Document intelligence - comfortable working with document parsing & extraction pipelines (OCR, layout analysis, structured extraction, etc) You're Likely a Fit If You've designed, built, and shipped something with LLMs or Agents with real users You're comfortable making decisions and backing up your logic You default to shipping over planning.
