About the Role
Join an early-stage AI company building multimodal agents for customer conversations across voice, SMS, and email. You will own a core product or engineering domain end to end, working closely with customers and the team to shape the product and bring improvements into production.
What You'll Do
Own a product or infrastructure domain from architecture through daily production releases.
Speak with customers, synthesize feedback, and make product decisions without a dedicated product manager.
Build and optimize multimodal agents, including low-latency voice experiences and persistent 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
Three to eight years of full-stack engineering experience, with a track record of shipping and scaling products from early development into broader use.
Production proficiency in TypeScript, Node.js, React, and Next.js, plus experience building Python services.
Hands-on experience shipping production systems with LLM APIs or agent SDKs.
Depth in at least one area: production voice or SMS agents, long-running agent state and memory, agent evaluations and guardrails, or B2B2C and marketplace products.
Experience making independent product decisions, conducting customer discovery, and owning projects through launch.
Strong AI or agentic systems experience, including work with low-latency requirements and unpredictable system behavior. Voice pipeline or evaluation tooling experience is useful.
Comfort working in an early-stage environment with changing priorities and limited process.
