React Native Full Stack Developer Jobs in Fort Wayne, IN

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.

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.

• Design and develop standardized, well-documented APIs using Fastify and OpenAPI spec, ensuring clear versioning and predictable integrations.
  
• Use Stainless and similar tooling to generate SDKs for common languages (TypeScript, Python, etc.).
  
• Implement new features and enhancements across the stack using TypeScript / JavaScript (ESModules), React 19, TailwindCSS, Bootstrap 5.3, and MongoDB.
  
• Maintain and extend BlueHive's API-first architecture, focusing on modularity, scalability, and performance.
  
• Collaborate with Product and Partner Engineering to integrate with HRIS, ATS, and EHR systems.
  
• Participate in daily stand-ups, code reviews, and sprint planning to ensure high-quality, maintainable code.
  
• Create automated tests (unit, integration, and end-to-end) to support CI/CD pipelines and prevent regressions.
  
• Track work in GitHub Projects and BlueHive's internal ticketing systems, ensuring progress visibility and alignment with OKRs.
  
• Contribute to internal coding standards and mentor peers on API-driven development best practices.
  
• Leverage AI development tools (e.g., GitHub Copilot, Cursor, OpenAI API) to improve efficiency, generate code prototypes, and maintain code quality.
  

Education

• 5+ years of professional software-development experience (2+ years at senior level).
  
• Bachelor's degree or equivalent practical experience preferred.
  

Technical Experience

• Proficiency in TypeScript / JavaScript (ESModules) and modern Node.js development.
  
• Strong understanding of API design principles (REST, OpenAPI, SDK generation workflows).
  
• Experience with Fastify, Express, or similar high-performance frameworks.
  
• Familiarity with MongoDB and reactive data layers in full-stack JavaScript applications.
  
• Experience building front-end features with React or Blaze, styled with TailwindCSS / Bootstrap 5.
  
• Comfort with Linux / macOS development environments and Git-based workflows.
  
• Familiarity with Meteor 3+ is a plus but not required.
  
• Proficiency with AI-assisted development tools such as GitHub Copilot, Cursor, or OpenAI Codex, including prompt engineering and understanding of AI model limitations and debugging.
  

Preferred Experience

• Exposure to API marketplaces or platform-as-a-service environments.
  
• Knowledge of testing frameworks such as Jest, Mocha, Cypress, or Playwright.
  
• Understanding of authentication/authorization standards (OAuth 2.0, OpenID Connect, SSO).
  
• Experience collaborating on OpenAPI-driven documentation pipelines.
  

• Strong communication and collaboration abilities across cross-functional teams.
  
• Proactive, ownership-driven approach to problem solving.
  
• Thrives in a remote, fast-paced, startup environment where priorities evolve.
  
• Passionate about AI-augmented development, clean code, and building developer-friendly systems.
  
• Curious and experimental mindset—willing to learn, adapt, and teach others how to use AI effectively in software engineering.
