Founding Engineer
About the Role
Join a small, fast-moving team building multimodal AI agents across voice, SMS, and email. As a founding engineer, you will own a core product or engineering domain end to end, shape product decisions with customers, and help establish the quality and architecture of production AI systems.
What You'll Do
Own a domain from architecture through implementation, shipping and improving production features.
Speak with customers, synthesize feedback, and make product decisions independently.
Build and optimize multimodal agents, including low-latency voice experiences, messaging workflows, and conversation state across channels.
Set quality practices for non-deterministic systems, including evaluations, prompt versioning, guardrails, and drift detection.
Work across React and Next.js frontends, Node.js backends, and Python services.
What We're Looking For
Typically 3 to 8 years of full-stack engineering experience, with a record of building and scaling products from 0 to 1 in a startup, founder, or new-product environment.
Production proficiency in TypeScript, Node.js, React, and Next.
