Founding AI Agent Engineer

About the Role

Join an early-stage healthtech team building AI agents for clinical trial recruitment and patient support. You will own the development of patient-facing conversational agents, helping make trial recruitment more efficient while maintaining safe, reliable interactions in a regulated field.

What You'll Do

• Build and orchestrate AI agents that coordinate patient recruitment across multiple clinical trials.

• Review production conversation traces, identify failure scenarios, create evaluations, and improve the agent harness.

• Integrate health profile data sources to support timely, relevant patient outreach and trial screening.

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

• Hands-on engineering experience focused on AI agents or large-scale AI applications, including conversational agents and agent harnesses used beyond prototypes.

• Experience developing evaluations and tracing infrastructure for production AI agents.

• Strong software engineering fundamentals, with applied LLM experience and familiarity with tools such as LangGraph, Vercel AI SDK, voice AI, SMS APIs, and multi-agent orchestration.

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

• A proactive, resourceful approach to solving difficult engineering problems; experience or interest in healthtech, healthcare, or life sciences is valued.
