AI Startup · Toronto, Canada (In-Person downtown Toronto)

About Us
We're solving one of the largest problems in the physical world: housing that's too slow and too expensive to build. The $2 trillion construction industry runs on human expertise that doesn't scale - so we're building the AI that understands what to build and how to build it.
We start with the costliest problems for general contractors - the multi-million-dollar decisions that Claude cannot solve. Tyce Agent wins more projects and estimates costs on multi-million-dollar builds live at one of the landmark construction companies today.
We just closed a 7-figure round and are hiring to build the best AI platform for construction.

What You'll Do
You'll own the backbone: the APIs, data model, integrations, and systems that everything else stands on. A true generalist who's happiest owning a problem end-to-end.
• Build core backend systems in FastAPI + PostgreSQL - APIs, data model, auth, org/permissions.
• Handle the but critical parts: security, multi-tenancy, reliability, observability.
• Drop into the frontend (React / TypeScript) whenever the product needs it.
• Ship new features day-to-day alongside the founders and make real architectural decisions.
We're on a modern, lean stack: React Router framework, TypeScript, FastAPI, PostgreSQL, Pydantic-AI, Logfire, AWS.

Required Qualifications
• Mid-to-senior level of engineering experience.
• Expert in Python; strong in TypeScript / React.
