About this role
About the Role
Join an early-stage team building multimodal AI agents for customer communication across voice, SMS, and email. You will own a core product or technical domain, work directly with customers, and help shape product decisions as the platform grows.
What You'll Do
- Own a domain end to end, from system architecture through shipping and operating production features.
- Join customer conversations, identify needs, and make product decisions in a fast-moving environment.
- Build and improve multimodal agents, including low-latency voice experiences and persistent conversations across channels.
- Set quality practices for non-deterministic systems, including evaluations, prompt versioning, guardrails, and drift detection.
- Contribute 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 delivering products from early development through growth at startups, established technology companies, or as a founder.
- Production proficiency with TypeScript, Node.js, React, and Next.js, plus hands-on experience building with LLM APIs or agent SDKs.
- Experience owning and shipping production AI or agent systems, with depth in at least one area such as agent memory and state, evaluations and guardrails, voice or SMS agents, or marketplace and B2B2C products.
- Strong product judgment, including customer discovery and making decisions without relying on a dedicated product manager.
- Full-stack capability, including Python services for real-time systems or evaluation tooling, and experience with low-latency systems and persistent cross-channel data.
- Strong technical fundamentals, an ability to work independently in an early-stage environment, and a record of sustained ownership and measurable product impact.
