Applied AI Engineer II - Amigo, Inc - New York, NY

ABOUT AMIGO

Amigo partners with healthcare organizations to deploy robust AI infrastructure that directly serves patients and providers. Our agents handle clinical workflows and patient engagement across the entire journey: pre-visit intake, care navigation, post-visit care plans, patient monitoring, and more.

We're fresh off our Series A backed by Tier 1 investors like Madrona, General Catalyst, and Optum Ventures. Our work is validated with leading academic medical institutions. Our agents have reached 3M+ patient encounters and are on track to 10x this year.

ABOUT THIS ROLE

As an Agent Engineer II at Amigo, you'll independently design and implement production AI agents for healthcare customers. You'll architect context graphs that model complex clinical workflows, design agent personalities that maintain clinical safety, and build evaluation frameworks that catch problems before patients encounter them. This role requires you to make design tradeoffs -- balancing conversation quality, clinical safety, and system reliability -- with minimal oversight.

WHAT YOU'LL DO

- Design context graphs (hierarchical state machines) that model multi-step clinical workflows -- choosing between linear arcs and routing hubs, calibrating state density, and preventing conversation loops

- Architect agent identities: background, motivations, expertise, behaviors, and communication patterns that produce clinically safe and engaging conversations

- Build dynamic behavior sets that inject contextual instructions at runtime -- designing trigger conditions, choosing override modes, and testing activation patterns

- Design user memory systems by defining extraction dimensions that are bounded, orthogonal, and actionable -- preventing the dimension overlap and storage explosion that collapse memory systems

- Write tool integration specs that define when tools fire, what parameters they receive, and how results persist in conversation context

- Diagnose production conversa
