About the Role

Join an early-stage healthtech company developing AI agents for clinical trial recruitment and patient support. You will build and own patient-facing conversational agents, helping research teams connect with eligible participants while maintaining safe, consistent experiences in a regulated setting.

What You'll Do

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

• Review production conversations, identify failure scenarios, develop evaluations, and use results to improve agent infrastructure.

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

• Evaluate and incorporate advances in agent tooling and research into the software platform.

What We're Looking For

• Hands-on experience building conversational agents and agent harnesses for real users at scale, beyond prototypes or internal tools.

• Experience developing evaluation and tracing infrastructure for AI agents.

• Strong software engineering fundamentals, with a full-stack background and applied LLM experience.

• Familiarity with conversational AI, multi-agent orchestration, voice or SMS systems, and tools such as LangGraph or Vercel AI SDK.

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