Staff Software Engineer - Backend/Infra NYC or SF - 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 a Staff Backend/Infra Engineer 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.

WHAT YOU'LL DO

• Designing high-throughput services that handle concurrent conversations at scale
• Owning a core platform service from design to production
• Building systems that stay available and degrade gracefully when things fail
• Handling sensitive healthcare data with the care it requires
• Improving performance, observability, and operational health across services
• Shaping architectural decisions as the platform grows

WHAT WE'RE LOOKING FOR

• You've built and operated production backend systems at scale and owned the outcome
• You're strong with concurrency, distributed systems, and service design
• You prefer simple, maintainable solutions to hard problems
• You debug well across services, queues, and databases
• You're low ego, direct, and hold yourself to a high bar
• You can work on site in New York City or San Francisco

NICE TO HAVE

• Experience in a regulated or high-reliability domain (healthcare, finance, legal)
• High-throughput or low-latency system design
• Event streaming and message queues
• Experience with production AI or ML systems
