Full Job Description

đź“‹ Description

  • • Design and execute structured, statistically rigorous experiments to evaluate and improve Mia, an AI voice agent handling inbound patient calls for healthcare providers.
  • • Build and maintain regression test coverage to detect unintended side effects of prompt changes across multi-turn, voice-first workflows.
  • • Create a validated pipeline of AI improvements that Engineering can confidently deploy, replacing intuition-based changes with evidence-backed decisions.
  • • Own the design, testing, and iteration of prompts across all Mia agent workflows, ensuring alignment with healthcare context, compliance, and user intent.
  • • Stay current with emerging research in prompting techniques, agentic architectures, and LLM evaluation, translating academic and industry advances into testable prototypes.
  • • Prototype new prompting and agent behavior approaches locally before any changes are introduced to production systems.
  • • Serve as the primary resource for Product and Engineering teams when resolving complex prompting challenges or ambiguous AI behaviors.
  • • Translate experimental results into clear, actionable recommendations for both technical and non-technical stakeholders.
  • • Develop reusable evaluation templates, behavioral test suites, and validation frameworks to institutionalize rigorous AI assessment practices.
  • • Collaborate with cross-functional teams to prioritize experiments based on impact, feasibility, and alignment with clinical and operational goals.
  • • Evaluate and interpret LLM behavior to understand why systems succeed or fail in specific patient interactions, using both quantitative metrics and qualitative analysis.
  • • Work with RAG systems and modern LLM tooling to enhance Mia’s contextual accuracy and reliability in high-stakes healthcare scenarios.
  • • Ensure all AI improvements are validated for safety, consistency, and compliance within regulated healthcare environments.
  • • Communicate findings through written reports and presentations that bridge the gap between research insights and product implementation.
  • • Maintain a deep focus on real-world patient outcomes, ensuring AI enhancements improve both clinical efficiency and patient experience.

🎯 Requirements

  • • 5+ years of experience in a prompting, AI research, or applied AI role
  • • Advanced degree in a research-oriented field (PhD preferred) in CS, linguistics, cognitive science, stats, or similar
  • • Real prompt engineering experience — deliberately designing, testing, and improving prompts to change system behavior
  • • Solid experimental design fundamentals: controls, statistical significance, understanding when results are meaningful
  • • Hands-on experience working with LLMs in applied contexts
  • • Comfort with RAG, agentic architectures, and modern LLM tooling

🏖️ Benefits

  • • Base salary: $180,000 - $230,000
  • • Meaningful equity ownership in a fast-growing healthtech startup
  • • Work on an AI voice agent used in real healthcare settings with direct patient impact
  • • Collaborate with a founding team with proven experience scaling technology at Carbon Health
