About the Role
Join an early-stage AI-powered sales automation startup as a Founding Engineer. You will own a core product or engineering domain, work directly with customers, and help shape multi-channel AI agents across voice, SMS, and email.
What You'll Do
Own a domain end to end, from system architecture through daily production releases.
Join customer calls, gather feedback, and make product decisions independently.
Build and optimize multi-channel AI agents, including low-latency voice experiences and persistent conversation state.
Set quality practices for non-deterministic systems, including evaluations, prompt versioning, guardrails, and drift detection.
Work across React and Next.js interfaces, Node.js backends, and Python services.
What We're Looking For
Three to eight years of full-stack engineering experience, including experience shipping early-stage products at startups, as a founder, or on new product teams.
Strong production skills in TypeScript, Node.js, React, and Next.js, plus experience building with LLM APIs or agent SDKs.
