Job summary

Flagler Health is building the clinical operating system for modern musculoskeletal care, and Senior Fullstack Engineers will own the main product surface end to end in a single monorepo using Vue 3, TypeScript, Express, and MongoDB.

You will move across the stack, model health data, design contract-first APIs, and integrate with EHRs and external systems, tackling complex data in a growing healthcare tech platform.

Qualifications

• 5+ years building and shipping production web applications, including 3+ years of health care revenue cycle management experience
• Strong TypeScript across the stack
• Hands-on experience with modern front-end framework such as Vue or React
• Backend experience with Node, Express, and MongoDB/Mongoose
• You know what your queries cost. Patient, clinical, and financial data gets large and wide fast, and the difference between a query that scales and one that falls over is usually an index or a schema decision made months earlier
• You can name the shortcomings of the tools you use, not just their features
• You've designed for growth you couldn’t fully predict, and can explain what you’d do differently now
• You've worked in a large codebase you didn't write and improved it rather than rewriting it
• Experience moving health data between systems: HL7, FHIR, EHR connectivity
• You've built complex yet auditable systems geared towards visibility
• Experience processing financial events while effectively managing states for each transaction
• You've created configurable state machines and rule engines that can be easily tweaked to handle new cases with minimal code changes and long term maintenance

Responsibilities

• Build screens against our internal component library
• Design and implement API routes contract-first, with schemas shared across frontend and backend
• Model clinical and revenue cycle data in MongoDB, and keep it queryable as collections grow
• Work inside shared TypeScript packages every app in the repo depends on
• Take features from spec to production and support them once they’re live
• Work across the full revenue cycle, from pre‑visit clearance through payment
• Integrate with the EHRs and external systems that our clients already run on
