Founding Full Stack Software Engineer (Backend-focus)

Summary

Build the backend APIs, data model, and integrations for an AI platform that optimizes construction cost estimation and project wins using FastAPI, PostgreSQL, and React.

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.


Competitive salary and equity.
