Integration Engineer Job Description Remote · Work from anywhere (minimum 2–3 hours overlap with US Eastern) ** 20–25 hrs/week · 6-month renewable contract** About Zingage Zingage builds AI-powered operations software for US home-care agencies. Hundreds of agencies rely on us every day to keep caregivers scheduled, shifts covered, and families supported. When our system works, someone’s grandmother gets care on time. When it doesn’t, they don’t. We’re a fast-growing US startup, well funded by top-tier US investors, and we move quickly. Our product combines AI agents, automation, and deep integrations into the systems our customers already use. The Role You’ll Play Home-care agencies run on legacy EMR systems (WellSky, AxisCare, AlayaCare, HHAX, others). Our AI and internal tools need to read and write into these systems reliably: update visits, attach notes, change caregiver details, and more. You will be the primary engineer responsible for our EMR integrations: Design and build the integration layer that sits between Zingage and multiple EMRs. Make sure core workflows (like updating a visit) work the same way across different systems. Keep integrations healthy as EMRs change their behavior over time. You won’t just “add endpoints.” You’ll shape how we model and implement integrations across the company. Why This Role Matters You connect our AI to the real world. Without solid integrations, our agent is just ideas and demos. You own a critical path. If integrations break, schedulers and caregivers feel it immediately. You define the pattern. The way you structure the first few EMRs will influence how we scale to the next ten. You touch a lot of surface area. Scheduling, notes, tasks, messaging, payroll flows—many teams will depend on the layer you build. What You’ll Do Build and extend EMR integrations Implement and maintain backend logic to create, update, and read key objects (visits, notes, caregivers, clients, etc.). Normalize different EMR behaviors into consistent flows Zingage can depend on. Design clean integration interfaces Work with our core backend team to define how internal services and AI tools call into EMRs. Avoid per-EMR one-offs; push for patterns that can be reused across systems. Create small tools and CLIs Write TypeScript/Node command-line tools to exercise integrations, debug issues, and help our internal teams operate faster. Keep integrations reliable Add tests and fixtures so we can detect breakage early. Monitor for changes in EMR behavior and ship fixes quickly. Collaborate closely with the core team Work with backend engineers, data engineers, and the AI team on priorities and design. Communicate clearly in writing (Slack, PRs, short docs); most of our collaboration is async. What You’ll Bring 3–7 years of backend engineering experience. Strong experience in at least one modern backend stack (Node/TypeScript, Java, Go, etc.), and willingness to work in TypeScript + Node.js day-to-day. Comfort working with: Web APIs and HTTP semantics Relational databases (PostgreSQL or MySQL) Basic schema and data modeling Real experience dealing with messy production systems, ideally in domains like: E-commerce (JD.com, Taobao, Pinduoduo, Meituan, etc.) Payments, logistics, or other transactional systems Hands-on experience with web behavior and automation, for example: Chrome DevTools (network, cookies, headers, form data) Browser automation tools (Playwright, Puppeteer, Selenium, etc.) HTML parsing (BeautifulSoup, Cheerio, or similar) Traffic inspection tools (e.g., Charles Proxy, Fiddler, Burp, etc.) A work style that: Breaks down unclear systems into clear steps Prefers simple, reusable designs over one-off hacks Communicates crisply and takes end-to-end ownership Clear written English is important. You don’t need to be perfect, but your code, comments, and Slack messages should be easy for the team to understand. What You’ll Gain High-impact ownership. You’ll be the main person responsible for how Zingage talks to multiple EMRs—this is core infrastructure, not side work. Exposure to AI in production. You’ll see how agents, voice, and integrations combine to run real operations at scale. A close-knit engineering team. You’ll work directly with founders and senior engineers, without layers of management or heavy process. Room to grow the scope. As we add more EMRs and more workflows, this role can expand in responsibility and hours if that’s what you want.
