Staff Software Engineer (Backend)

Amigo builds AI agents that deliver healthcare autonomously—AI doctors, AI nurses, and AI care coordinators. Our agents handle clinical workflows and patient engagement across the entire patient journey: pre-visit intake, triage, care navigation, post-visit care plans, side effect management, and medication adherence. Context-aware with memory across sessions and the ability to take clinical action.

We own outcomes, not just delivery. For our customers, we're responsible for agent performance: clinical safety, continuous improvement, measurable patient outcomes. Agents operate autonomously within bounded clinical domains, with clear scope and handoff protocols. That scope expands as we validate performance across populations.

We're fresh off our Series A from Tier 1 investors like General Catalyst, GSV Ventures, SVA, and CohoVC. Our work is validated with leading academic medical institutions. We're currently reaching 1M+ patient interactions every 90 days, and are on track to 10x this year.

As a Staff Software Engineer (Backend) at Amigo, you'll own the technical direction of the backend systems that power our agent platform at scale. You'll architect high-performance services handling millions of conversations, drive engineering standards, and make critical decisions on system design for real-time inference, LLM orchestration, and healthcare integrations.

You'll mentor engineers, shape technical culture, and ensure we maintain elite engineering standards as the team grows. These systems handle sensitive patient data and support clinical workflows—correctness and reliability are non-negotiable.
