Senior Full Stack Developer

MIE is seeking a Senior Full-Stack Developer to help shape the next chapter of our occupational health platform—a system that connects employers, providers, and employees through a secure, intelligent API layer.

In this role, you’ll work across the stack to build scalable services and standardized APIs that form the backbone of BlueHive’s API-first architecture—our effort to become the DoorDash Drive / Stripe of occupational healthcare. You’ll design and implement OpenAPI-defined endpoints using Fastify, leverage tools like Stainless to generate SDKs (TypeScript, Python, etc.), and ensure consistency across integrations with HRIS, ATS, and EHR platforms.

Beyond backend excellence, you’ll contribute to a modern web experience using TypeScript, React 19, TailwindCSS, and MongoDB, collaborating closely with product, design, and DevOps teams to deliver clean, reliable, test-driven code.

We’re especially looking for developers who embrace AI-assisted development—engineers who can harness tools like GitHub Copilot, Cursor, or OpenAI Codex, understand prompt design, and know how to collaborate effectively with AI coding agents to increase productivity without compromising quality.

If you’re an adaptable engineer who thrives on autonomy, values good API design, and wants to help standardize how occupational health services connect across the industry, we’d love to hear from you.

Company Overview

MIE and BlueHive’s mission is to simplify occupational health management through automation and connectivity. Our platform helps organizations stay compliant, keep teams healthy, and streamline communication with a network of more than 18,000 healthcare providers.

We’re building an API-first infrastructure for the industry—embedding BlueHive directly within HRIS, ATS, and EHR systems to make ordering and managing occupational health services as easy as placing a delivery or running a payment.

As part of the Medical Informatics Engineering (MIE) family, we combine the stability of a proven healthcare organization with the agility of a startup—developing innovative, web-based solutions that improve health outcomes and operational efficiency.
