Ruby Rails Python React TypeScript GraphQL Postgres AWS Full Stack Senior LLM AI Construction Compliance Remote AI Engineer Full Stack Engineer

Company: Ichi
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 are a small team (employee #6) backed by Costanoa Ventures. 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.

Role & Responsibilities:
We’re looking for a high-ownership, high-accountability Full Stack Senior Software Engineer who isn’t just here to write code but to deeply care about the outcome of what we build. You will own the full product lifecycle—from brainstorming and technical design to implementation and release. You'll design and implement product features that integrate intuitive UX and powerful multi-modal (and multi-model) LLM pipelines. You'll navigate trade-offs thoughtfully, making decisions with customer impact in mind. Collaborate closely with internal customers to deeply understand their needs, ensuring we’re building the right things. Develop and scale a system that seamlessly integrates multiple LLMs while avoiding dependence on a single model. Work within a small team to define and execute the technology strategy, reporting to the Head of Engineering. Engage directly with users, gathering feedback to continuously refine and improve our solutions.

Technical Skills & Experience Required:
*   8+ years of professional engineering experience in tech and product-driven companies (excluding internships).
*   Full stack experience in some capacity— with a willingness to learn and grow across the stack (Tech stack: Ruby, Rails, Python, React, TypeScript, GraphQL, Postgres, AWS).
*   Experience building and launching software from scratch that others have used.
*   Rails and/or React expertise and experience building production-grade applications.
*   Interest in AI / LLMs – you’ve used AI-powered tools in your workflow or even experimented with building AI-powered prototypes.

Ideal Candidate:
*   Strong product intuition—you care about the impact of what you build, not just checking off tasks.
*   Ability to work with limited direction and thrive in ambiguity, driving initiatives forward independently.
*   Deeply cares about product quality and thinks long-term about what makes a product truly great.
*   First-principles thinking and attention to detail are essential.
*   Comfort working in a Pacific Time-based environment (remote within the U.S.).
*   CS degree or equivalent foundational experience in computing preferred.
