Senior Full-Stack Engineer, AI-Powered RCM

We're looking for a senior full-stack engineer to join greenfield product development on a new AI-powered revenue cycle management (RCM) product — built on a platform that moves dental records and imaging (CBCT, DICOM) between general practices, specialists, and dental schools. The engagement is fractional and milestone-based, with a quick sprint cadence and no fixed working hours — work is measured by shipped features and merged PRs. It can grow into a larger ongoing commitment as the product scales. Your responsibilities will include: Building full-stack features in TypeScript / Node.js (Express, MySQL, Redis, Zod) and React 18 (Vite, TanStack Query, Tailwind); Integrating LLMs into product workflows — we build with Claude — including model harnesses, structured outputs, and data pipelines; Working with structured healthcare data and claims flows; Submitting PRs to dev and passing the same review and CI gates as the core team (GitHub Actions, dev → staging → prod). What we expect from you: Senior-level full-stack TypeScript / Node.js experience; Hands-on AI / LLM integration experience in production; Strong React product UI skills; Experience with data pipelines and structured data; Strong English; ability to self-manage as an independent contributor; Daily use of AI tooling (Claude, Cursor) in your workflow; US healthcare / claims / RCM domain experience; HIPAA / PHI handling experience. We offer: Interesting product challenges at the intersection of healthcare data and AI; Work in a small, focused founding team with a modern, AI-native development practice; Flexible fractional engagement — outcome-driven, no fixed hours, fully remote; Milestone-based cadence with room to grow into a larger ongoing commitment; Lack of bureaucracy and direct collaboration with the founding team; Trial period to validate the fit before scaling up the engagement.
