Founding Product Engineer for AI-Native Ops

TechTree, a pre-seed startup in San Francisco, is building an operating system for AI-native service businesses. You will be the first dedicated product engineer, owning the entire product experience from sketch to production. You’ll design and ship interfaces that businesses trust to manage their AI agents, turn customer learnings into product decisions, and set the design bar as the team grows. This is a founder-level, in-person role.
