Full Job Description
ABOUT THE ROLE Hello Patient is seeking a Prompting & AI Agent Research Engineer to bring structure and rigor to how we advance our AI. We build Mia, an AI voice agent that handles inbound patient calls for multi-location healthcare providers - and as we grow, we need someone who can help us make more confident, evidence-backed decisions about how Mia evolves. You'll design experiments we can trust, stay close to what's emerging in the research community, and turn promising ideas into something testable. This role sits at the intersection of prompt engineering and applied AI research. You should be comfortable enough technically to prototype and run local experiments independently. Above all, we're looking for someone with deep, hands-on prompting experience - someone who has deliberately engineered prompts to change how a system behaves. WHAT YOU'LL DO EXPERIMENTATION & EVALUATION - Design structured experiments with real controls and statistical rigor - Build regression test coverage so we know when a global prompt change is breaking things across workflows we didn't expect - Create a pipeline of validated, high-confidence improvements engineering can pull from instead of building on faith - Work with the team to prioritize what actually gets shipped based on what the experiments say PROMPTING & AGENT ARCHITECTURE RESEARCH - Own prompt design across Mia's agent workflows - multi-turn, voice-first, healthcare context - Stay current on what's coming out in prompting research, and agent architecture, and bring back ideas worth testing - Prototype new approaches locally before anything touches production - Be the person the Product team comes to when they're stuck on a prompting problem COLLABORATION & KNOWLEDGE SHARING - Work closely with our Product and Engineering teams - understand where Mia is struggling and help decide what's worth experimenting on - Translate experiment results into clear recommendations people can actually act on - Build out evaluation templat
