About The Position

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. As a Senior Software Engineer (Backend) at Amigo, you'll build the core services behind our agent platform. The systems you own handle millions of conversations a month, so concurrency, reliability, and clean design are the job itself, not an afterthought. You'll own services end to end, from design through production.
