Position Overview

We are looking for a highly hands-on Lead Full-Stack Developer with strong experience in Java, Spring Boot, React.js, Microservices, and healthcare domain applications.

The ideal candidate will have practical experience developing and supporting healthcare applications, particularly healthcare claims processing, pricing workflows, routing rules, and integrations with HealthEdge.

This role requires someone who can independently design, develop, debug, test, and deploy application components while providing technical guidance to a distributed offshore development team.

The candidate should be comfortable working across the entire software development lifecycle, from understanding business requirements and implementing backend services to troubleshooting production issues and supporting deployments.

Candidates with prior HealthEdge integration experience and healthcare claims/pricing domain knowledge are strongly preferred.

Key Responsibilities

1. Healthcare Domain & HealthEdge Integration

• Develop and maintain healthcare applications involving claims processing, pricing, and routing workflows.
• Understand healthcare claims lifecycle, including how claims are received, processed, priced, routed, and transmitted to external healthcare platforms such as HealthEdge.
• Develop and maintain integrations with HealthEdge, including request/response processing, data mapping, validation, and error handling.
• Understand how claims are submitted to HealthEdge, how pricing is performed, and how responses are received and processed by downstream systems.
• Troubleshoot claims processing failures, pricing discrepancies, integration issues, and routing-related problems.
• Collaborate with product owners, business analysts, and technical teams to translate healthcare business requirements into technical solutions.

2. Backend Development – Java & Spring Boot

• Design, develop, and maintain scalable backend applications using Java and Spring Boot.
• Build RESTful APIs and microservices to support healthcare business workflows.
• Work with modern Java versions, preferably Java 17 or Java 21.
• Implement business logic, validation, exception handling, transaction management, and API integrations.
• Develop reusable components and maintain clean, scalable, and maintainable code.
• Implement unit and integration testing using JUnit, Mockito, and related frameworks.

3. Microservices & Distributed Systems

• Design, develop, and support microservices-based applications.
• Containerize applications using Docker and deploy services using Kubernetes.
• Demonstrate practical, hands-on experience with Docker and Kubernetes, including at least six months of production or project implementation experience.
• Work with Kafka or similar event-streaming technologies for asynchronous communication and event-driven processing.
• Implement service-to-service communication, resilience, error handling, and distributed transaction patterns.
• Understand microservice data persistence strategies, including database-per-service architecture, transactional and read-only database access, and shared connection pool management where appropriate.

4. CI/CD, Deployment & Production Support

• Understand and actively participate in the complete CI/CD lifecycle.
• Independently build, troubleshoot, and deploy application code across Development, SQA, and Production environments.
• Work with CI/CD pipelines, automated builds, testing, deployment, and release management.
• Debug application issues locally and across deployed environments without depending entirely on separate DevOps or deployment teams.
• Troubleshoot production incidents, identify root causes, and implement permanent fixes.
• Demonstrate practical experience resolving real-world performance, integration, database, and microservices issues.

5. Frontend Development – React.js

• Develop and maintain frontend components using React.js.
• Integrate React applications with Spring Boot REST APIs.
• Implement reusable UI components, state management, form validation, and API error handling.
• Collaborate with backend and product teams to deliver end-to-end application functionality.

6. Technical Leadership & Offshore Team Collaboration

• Provide hands-on technical guidance and support to offshore development teams.
• Participate in solution design, code reviews, technical discussions, and development planning.
• Review code for quality, maintainability, security, and performance.
• Ensure offshore deliverables align with architecture, engineering standards, and business requirements.
• Support knowledge sharing, technical mentoring, and effective collaboration across distributed teams.
• Remain actively involved in coding and technical implementation rather than focusing exclusively on team management.

Must-Have Skills

• 8–12+ years of professional software development experience.
• Strong hands-on expertise in Java and Spring Boot.
• Experience with modern Java versions, preferably Java 17 or Java 21.
• Strong practical experience developing REST APIs and microservices.
• Hands-on experience with React.js and full-stack application development, with approximately 80% backend and 20% frontend responsibilities.
• Strong healthcare domain experience, preferably involving claims processing, healthcare pricing, and routing workflows.
• Prior HealthEdge integration experience is highly preferred.
• Practical experience with Docker and Kubernetes, with at least six months of hands-on implementation experience.
• Working knowledge of Kafka or similar event-streaming platforms.
• Experience with CI/CD pipelines and the complete Development → SQA → Production deployment lifecycle.
• Ability to independently develop, debug, test, and deploy application code.
• Understanding of microservices data persistence, database transactions, connection pooling, and distributed systems.
• Experience troubleshooting real-world production issues and performing root-cause analysis.
• Experience working with distributed/offshore development teams.

Nice-to-Have Skills

• Direct experience integrating applications with HealthEdge platforms.
• Strong knowledge of healthcare claims adjudication, pricing engines, claims routing, and payment workflows.
• Experience with Oracle Cloud Infrastructure (OCI), AWS, Azure, or other cloud platforms.
• Experience with Kafka streaming and event-driven architectures.
• Familiarity with GitHub Copilot and other AI-assisted development tools.
• Experience with Test-Driven Development (TDD), JUnit, Mockito, Selenium, and Cucumber.
• Experience with cloud-native application development and distributed system observability.
• Experience leading technical delivery across geographically distributed teams.
