About the Role

Zingage is hiring a Senior Backend Engineer to own the core decision engine behind our real-time care coordination platform.

We’ve built a system that ingests operational breakdowns (caregiver no-shows, missed visits), stores them as session objects, and supports manual SOP execution by human operators. Now we’re designing the scaffolding for a system that can autonomously coordinate care—in real time, with agents and humans working in a closed loop.

You’ll own the backend runtime that

• Plans and executes resolution loops based on SOPs
• Routes problems to the right agent or human
• Tracks what’s been tried, adapts when things fail, and drives every session to closure

This is the coordination brain of Zingage. You’ll work alongside Ethan (Principal Engineer, architecting the session model) and Jackie (Founding Product & Design Lead, defining the operator interface and SOP UX) to ship the system that actually solves the problems we detect.

What You’ll Do

• Design and implement the backend runtime that drives real-time resolution workflows (e.g., caregiver no-shows, missed documentation, last-minute coverage)
• Encode SOPs as structured, executable logic that can be retried, escalated, or overridden
• Build real-time coordination loops that integrate AI agents, humans, and notifications
• Implement fallback logic, retries, timers, and observability into the session loop
• Define interfaces between the session object and decision-making logic
• Collaborate closely with Ethan and Jackie to unify backend execution, agent routing, and operator control

Who You Are

4–8 years experience building backend system

You’re drawn to fields like robotics, control systems, or multi-agent coordination, and may have explored them in undergrad, grad school, or side projects

• You’ve read (or would read) papers like “BDI Agents: From Theory to Practice” and get excited by bridging cognitive architectures with real-world execution
• You’re decisive, rigorous, and thrive in ambiguous, high-stakes, high-velocity environments

Why Now

• Backed by Bessemer Venture Partners and Ramp’s founder (Ramp mafia DNA)

300+ live healthcare sites already using our system—real traction, not theory

Ingest pipeline and session model already built—now building the decision engine

• One of the only healthcare AI companies touching real care delivery—if our software fails, patients are left unattended in their homes
