• 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.
