Senior Software Engineer – Full Stack (Java, Spring Boot, React)

Location: Bangaluru, India (Hybrid)

Experience: 4–7 years

Domain: Healthcare Technology (Oncology / Clinical Platforms)

We are looking for a Senior Full Stack Software Engineer to design, build, and operate scalable, mission-critical healthcare applications.

This is a backend-first full-stack role (70% backend / 30% frontend) where you will primarily work on Java + Spring Boot microservices, while contributing to React-based UI layers to deliver complete end-to-end features.

You will also operate in an AI-first engineering environment, where tools like GitHub Copilot and Windsurf, Claude are used to accelerate development — with a strong expectation that you validate, refine, and productionize outputs to meet the security by design with enterprise-grade standards.

Key Responsibilities

Full Stack Development

• Design and build scalable microservices using Java, Spring Boot, and REST APIs
• Define clear API contracts (OpenAPI/Swagger) with consistent error handling and versioning
• Implement event-driven architectures using Kafka or equivalent messaging systems
• Build high-performance data access layers using JPA/Hibernate and Oracle/Postgres
• Develop and enhance UI components using React.js and TypeScript
• Build integration layers and admin UIs to support backend workflows
• Ensure end-to-end flow validation (UI → API → DB → events)
• Ensure production-grade reliability: transaction safety, idempotency, and error recovery

AI-First Engineering Mindset (Critical)

• Actively use AI tools (e.g., GitHub Copilot, Windsurf, Claude or any other Mckesson approved tools) to:
• Accelerate coding, refactoring, and test generation
• Improve developer productivity without compromising maintainability
• Critically evaluate AI-generated code for:
• Correctness and edge cases
• Security and data handling risks
• Performance and scalability
• Apply AI responsibly in:
• Code generation, debugging, and clear documentation
• Unit Test case creation and coverage improvement
• Design systems that are:
• AI-friendly (clear APIs, structured data, consistent contracts)
• Observable and diagnosable using logs, metrics, and traces
• Security by design

Engineering Quality & Delivery

• Write clean, maintainable, well-tested code (unit + integration tests)
• Participate in code reviews, design discussions, and architecture decisions
• Work in Agile teams with strong accountability & ownership of delivery
• Diagnose and resolve production issues using observability tools, such as Dynatrace

Platform & System Thinking

• Build services that are:
• Reusable
• Well-documented
• Easy for other products to integrate
• Follow best practices in:
• API design
• Microservices architecture
• CI/CD and DevOps pipelines

Minimum Requirement

Must-Have Skills

• 4–7 years of software development experience in product/enterprise environments
• Strong hands-on experience with:
• Java (17+) and Spring Boot
• REST API design and microservices architecture
• Experience with React.js + TypeScript (at least 1-2 years)
• Solid experience with:
• SQL and relational databases (Oracle/Postgres)
• ORM tools (Hibernate/JPA)
• Experience with:
• Event-driven systems (Kafka or similar)
• Caching (Redis or similar)
• CI/CD pipelines and Git-based workflows
• Automated testing practices
• Strong debugging and production issue analysis skills

AI-First Expectations (Non-Negotiable)

Candidates must demonstrate:

• Practical use of AI coding assistants in development workflow
• Ability to review, validate, and production-harden AI-generated code
• Understanding that:
• AI accelerates development
• Engineers are still accountable for design, correctness, and quality

If someone blindly copies Copilot output, this role is not for them.

Foundational

• Clear written and verbal communication — ability to document services and explain technical decisions

Good-to-Have Skills

• Healthcare domain experience
• Familiarity with:
• FHIR / HL7 / C-CDA standards
• HIPAA compliance and PHI/PII handling
• Experience with:
• Databricks / data pipelines
• Elasticsearch / Redis
• Docker / Kubernetes

What Success Looks Like

• Deliver production-ready features end-to-end, not just code
• Build systems that are scalable, observable, and reusable
• Improve team productivity using AI without degrading quality
• Contribute to raising engineering standards across the team

Why This Role Stands Out

• Work on real-world healthcare systems impacting patient outcomes
• Exposure to modern architecture + AI-driven engineering practices
• Opportunity to build platform-grade services used across multiple teams
