Founding AI Agent Engineer

About the Role

Build and own patient-facing AI agents for a healthtech platform supporting clinical trial recruitment. This founding engineering role focuses on creating conversational experiences that can scale while remaining safe in a regulated industry.

What You'll Do

• Orchestrate AI agents that coordinate patient recruitment across multiple clinical trials.

• Analyze production conversations, identify failure scenarios, create evaluations, and improve the agent harness.

• Integrate health profile data so agents can engage patients at relevant moments and support trial recruitment.

• Scale language-model experiences across voice, SMS, and email while maintaining consistent, personalized conversations.

• Evaluate emerging agent tools and research and incorporate useful advances into the software platform.

What We're Looking For

• Zero to four years of experience as a software engineer, agent engineer, or applied AI engineer.

• Experience focused on building production AI agents or large-scale AI applications, beyond prototypes or internal tools.

• Experience building conversational agents and agent harnesses at scale, for text or voice.

• Experience developing evaluation and tracing infrastructure for AI agents.

• Familiarity with conversational AI, LLMs, multi-agent orchestration, LangGraph, Vercel AI SDK, voice AI, SMS APIs, or CTMS and CRM integrations.

• An undergraduate degree in computer science, mathematics, or a related field, with strong technical fundamentals.

• Ability to work independently, tackle difficult engineering problems, and make progress through ambiguity.

• Healthtech experience or a strong interest in the field is valued, as is experience with consumer-facing conversational products.
