Founding AI Agent Engineer

About the Role

Join an early-stage healthtech team building conversational AI agents for clinical trial recruitment. You will own the patient-facing agent as it scales across trials and communication channels, with a focus on making it both effective and safe in a regulated environment.

What You'll Do

• Build and orchestrate AI agents that coordinate patient recruitment across clinical trials.
• Review production conversations, identify failure scenarios, turn them into evaluations, and use the results to improve the agent harness.
• Integrate health profile data sources to support timely outreach and patient qualification.
• Scale language model experiences across voice, SMS, and email while keeping conversations consistent and personalized.
• Evaluate emerging agent research and tools, and incorporate relevant capabilities into the product.

What We're Looking For

• 0 to 4 years of experience as a software engineer, agent engineer, or applied AI engineer.
• Professional experience focused on agents or large-scale AI applications, including conversational agents and agent harnesses deployed beyond prototypes.
• Experience building evaluation and tracing infrastructure for AI agents and working with production traces.
• Familiarity with conversational AI, LLMs, agent orchestration, and tools such as LangGraph, Vercel AI SDK, voice AI, and SMS APIs.
• Strong CS, mathematics, or related technical fundamentals, typically supported by an undergraduate degree in a relevant field.
• Resourcefulness, strong execution, and the ability to work through ambiguous technical problems independently.
• Healthtech experience or a strong interest in healthcare is valued; consumer-facing conversational AI experience is relevant.
• Authorized to work in the United States without visa sponsorship and available to work on-site in the San Francisco Bay Area.
