Principal Fullstack Engineer (Member of Technical Staff)

Role overview

A principal fullstack engineering role focused on the foundation layer of a web application that brings humans and AI together to work on construction takeoffs. The position carries Member of Technical Staff responsibilities, reflecting broad influence over technical direction across the product. Work centers on architecture and core build rather than a single feature area, and suits engineers who enjoy defining the surface area other teams build on.

Responsibilities

- Own the product foundation that the rest of the engineering organization builds on - Architect the web application that supports human and AI collaboration - Build the core systems that enable construction takeoff workflows, where users measure and quantify materials from building plans - Set technical standards and patterns for fullstack development at the foundation level - Influence engineering direction across the stack through foundational decisions

Requirements

- Principal-level experience as a fullstack engineer in production environments - Demonstrated ability to architect and ship foundational web application layers - Depth across frontend and backend systems, including how they integrate - Track record of cross-cutting engineering impact that other teams rely on - Comfort owning foundational decisions and the trade-offs that come with them
