About the role
About the Role
Join a small team building multimodal AI agents for customer communication across voice, SMS, and email. You will own a core product or engineering domain end to end, shape decisions directly with customers, and help bring reliable AI systems into production.
What You'll Do
Own a domain from architecture through frequent production releases.
Speak with customers, synthesize feedback, and make product decisions independently.
Build and optimize multimodal agents, including low-latency voice experiences and persistent, cross-channel 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 services, and Python systems.
What We're Looking For
Three to eight years of full-stack engineering experience, with a record of shipping and scaling products from early stages in fast-paced environments.
Production proficiency in TypeScript, Node.js, React, and Next.js, plus experience building Python services.
Hands-on production experience with LLM APIs or agent SDKs, such as Anthropic, OpenAI, or comparable tools.
Strong 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 product decisions, conducting customer discovery, and owning shipped work without relying on a dedicated product manager.
Understanding of backend infrastructure and data structures for persistent conversations, as well as low-latency systems and non-deterministic behavior.
Python experience with real-time voice pipelines or evaluation tooling is useful. Strong computer science fundamentals or founder experience with demonstrated product traction are also valued.
Compensation & Benefits
Base salary: $180,000 to $250,000 annually. Visa sponsorship is not available.
Location
On-site, five days per week in New York, New York.
