Ichi is building an AI-powered professional toolset to transform construction permitting and code compliance. We're helping municipalities, plan examiners, architects, and construction professionals streamline the permitting process to reduce bottlenecks—ultimately accelerating construction timelines in an $11T global industry.
We're a small team (you == employee #6) backed by Costanoa Ventures looking for a high-ownership Senior Software Engineer (8+ years exp) who can build from scratch and deeply cares about product quality. You'll design and implement product features that integrate intuitive UX and powerful multi-modal (and multi-model) LLM pipelines, working directly with users to refine our approach.
Tech stack: Ruby, Rails, Python, React, TypeScript, GraphQL, Postgres, AWS.
Must have: Full stack experience, product intuition, and interest in LLMs.
CS degree or equivalent preferred; we work on hard problems and first-principles thinking and attention to detail are essential.
Our name "Ichi" (Japanese for "city", and "one") reflects our mission to improve the physical spaces around us through never-before-possible technology and bridging a fundamental information asymmetry.
