AI Agent Engineer

Ellipsis Health is creating cutting-edge AI/ML products that solve healthcare staffing issues and administrative burdens using conversational AI and our patented voice biomarker technology in the delivery of better healthcare for everyone. We are headquartered in Silicon Valley and are funded and supported by some of the most preeminent venture capital teams.

We’re seeking a creative and technically strong AI Agent Engineer with a passion for language and healthcare to help design, test, and refine prompts, and design tools for our AI-powered healthcare agents. In this role, you’ll work closely with engineers and our deployment team to refine and optimize prompts that ensure both clinical safety and a strong patient experience. You’ll play a central role in shaping how our large language models communicate with patients, providers, and care teams — ensuring that outputs are clinically sound, context-aware, and delivered with empathy. The ideal candidate blends engineering skill with a product mindset, thrives on iteration and experimentation, is meticulous in their approach, and has a deep interest in conversation design and natural language interactions.

Responsibilities

• Design and evaluate prompts for AI agents and tools that support healthcare tasks such as patient outreach, enrollment, symptom screening, and follow-up care
• Work closely with clinical, product, and engineering teams to ensure prompt outputs align with medical accuracy, regulatory guidelines, and user intent
• Develop and maintain a prompt library tailored to different patient populations, clinical scenarios, and communication channels (voice, chat, etc.)
• Evaluate performance of LLM outputs, identify error patterns, and iterate using structured testing and evaluation
• Incorporate inclusive language, health literacy best practices, and cultural sensitivity into prompt design
• Stay informed on LLM capabilities, fine-tuning strategies, and ethical standards for AI in healthcare
