Job Summary

We are seeking a Senior Full Stack Developer with deep expertise in Angular, React (MUI & React

Hooks), Java Spring Boot, Apache Kafka, GraphQL, and Azure Kubernetes (AKS) deployments.

You will architect end-to-end solutions, optimize performance across the stack, and lead the

security (OAuth2/JWT), and microservices patterns.

virtualized lists (React Window), and Lighthouse/Cypress audits.

• Tune backend performance with JVM profiling, connection pooling, caching (Redis),
  
  
  

query optimization, and async processing.

• Implement end-to-end tracing (OpenTelemetry) and monitoring (Prometheus +
  
  
  

Grafana).

• Cloud-Native Deployment & DevOps
• Containerize applications using Docker and orchestrate with Azure Kubernetes
  
  
  

Service (AKS).

• Implement CI/CD pipelines using Azure DevOps, GitHub Actions, Helm charts, and
  
  
  

infrastructure-as-code (Terraform).

• Ensure zero-downtime deployments, blue-green/canary strategies, and auto-
  
  
  

scaling policies.

• Testing, Quality & Reliability
• Lead comprehensive testing strategies:
  
  
  

 Frontend: Jest, React Testing Library, Cypress, Storybook

 Backend: JUnit 5, Testcontainers, Mockito, Spring Boot Test

 E2E: Playwright or Cypress with Kafka/GraphQL mocking

• Enforce code quality via SonarQube, ESLint, Prettier, and architectural reviews.
• Leadership & Mentorship
