# Principal Software Engineer (Remote)

About Dalton Mills Dalton Mills is the AI operating system for the trades. Any contractor can build the software their business actually runs on, in plain language, no code. The platform you build on. Not the software you put up with. Backed by Founder Collective, FPV, and angels including Gokul Rajaram. Every operator in the trades has a list of things their software can't do. The features aren't hard. They're too specific for any vendor to build for one slice of one trade, so the list sits there for years. Every item got the same answer from their software company: too niche to build. Ours is different. They build it themselves. We give every trade the same agentic rails underneath. From there, each operator shapes the software around how they actually work. The same product, opened by a forty-truck plumbing operation and a two-person pest control shop, becomes two different products. Every field service tool treats them the same. We're the first platform built to learn the difference. The role A true 0 to 1. No legacy code, no inherited stack, no roadmap handed down. You take a problem end to end. Design it, build it, ship it, watch it in production, iterate. Often in a day. In
