Software Engineer (SWE)

About Cair Health Backed by Y Combinator, Foundation Capital, Soma Capital, and other amazing investors, Cair Health has raised over $3M to build the agent-operated revenue cycle management platform for healthcare. We're at $1M+ ARR, profitable, and grew 21x last year. Our customers include clinics, MSOs, digital health companies, EHRs, FQHCs, billing companies, and more. Day to day, we work with operations leaders, heads of RCM, billers, and sometimes engineers. But the product itself is deeply technical, and every account eventually needs someone who can configure the system, troubleshoot integrations, or work directly with a customer's engineering team on our APIs and their data flow. About the role We're hiring a Software Engineer to build the core agent-operated platform underneath everything Cair does. A lot of what customers need starts as a one-off build for a specific account; your job is to take what works and turn it into a product: generalize it, harden it, and make sure the platform scales as we add customers. As one of our first engineering hires, you'll help shape the architecture, the agent framework, and the engineering practices that every future engineer inherits. What you'll do Own core parts of the agent-operated RCM platform, from architecture through production Take integrations and workflows built for individual customers and generalize them into the core product Design and build the agent framework and infrastructure that the rest of the team builds on top of Ship fast and iterate directly based on what customers and the field team are running into Debug and fix issues across the stack, from data pipelines to the agents themselves Set technical standards, code review practices, and engineering processes as an early hire Stay close to what customers actually need, not just what's on the roadmap Required You'll need a CS degree or equivalent hands-on experience and 3+ years in a technical, customer-facing role (solutions engineering, forward deployed engineering, implementation, or technical customer success). Deep software engineering fundamentals: system design, data modeling, testing, and the judgment to know when to generalize something versus keeping it simple Experience writing Python (or similar), SQL, and React on the front end Working knowledge of REST APIs Experience with AWS and GCP Comfortable with Docker, both running things locally and deploying them Hands-on experience building or working with AI agents Comfortable using AI coding agents (Cursor, Claude Code, OpenCode or similar) as part of your daily workflow, you ship faster because you use these tools well Track record of owning something end-to-end: designing it, building it, and keeping it running in production Comfortable reviewing code and setting technical standards, not just writing your own Nice to have Experience with EHR integrations, claims/billing systems, or healthcare APIs Early-stage startup experience wearing multiple hats Healthcare or RCM background Prior experience as a forward-deployed engineer, solutions engineer, or similar embedded engineering role
