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.
