Founding AI Agent Engineer

About the Role

Join an early-stage healthtech company building conversational AI agents for clinical trial recruitment and patient support. You will own the development of a patient-facing agent, helping shape the product as it expands across clinical trials and communication channels.

What You'll Do

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

• Review production conversation traces, identify failure scenarios, turn them into evaluations, and use results to improve the agent harness.

• Integrate health profile data sources to help agents contact and qualify potential trial participants.

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

• Evaluate emerging agent tools and research, and incorporate useful capabilities into the product.

What We're Looking For

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

• Hands-on experience building production conversational agents and agent harnesses at scale, beyond prototypes or personal projects.

• Experience developing evaluation and tracing infrastructure for AI agents.

• Applied LLM experience and a full-stack software engineering background; familiarity with agent orchestration, voice AI, SMS APIs, and tools such as LangGraph or the Vercel AI SDK is relevant.

• Strong CS, math, or related fundamentals, typically demonstrated through an undergraduate degree or equivalent experience.

• Interest or experience in healthtech, healthcare, or life sciences is valuable.

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