About the role

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.
