About the Role

Join an early-stage healthtech company building conversational AI to support patient recruitment for clinical trials. As a founding engineer on the agent team, you will own production AI systems that communicate with patients across multiple channels in a regulated setting.

What You'll Do

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

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

Integrate health profile data sources to help agents reach patients at relevant times and support trial recruitment.

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

Evaluate emerging agent research and tooling 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 agents and large-scale AI applications, including conversational agents or agent harnesses used in production.

Experience developing evaluation and tracing infrastructure for AI agents, beyond personal projects or prototypes.

Working knowledge of conversational AI, LLMs, agent orchestration, LangGraph or the Vercel AI SDK, voice AI, and SMS integrations.

Strong software and computer science fundamentals, supported by an undergraduate degree in computer science, mathematics, or a related field.

Resourcefulness, strong work ethic, and ability to independently unblock challenging engineering work.

Healthtech experience or interest is valuable, as is experience building consumer-facing AI products.

Must be authorized to work in the United States without visa sponsorship, and able to work on-site in the San Francisco Bay Area.

Compensation & Benefits

Base salary: $150,000 to $220,000 annually. Visa sponsorship is not available.
