Founding Engineer

About the role

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.
