About the Opportunity

Operating in the Information Technology & Software Development sector, this role supports enterprise-grade application development for customers across domains such as finance, SaaS, and digital platforms. We build scalable, resilient microservice-based systems that power mission-critical services and high-throughput integrations.

Primary title: Java Developer – Spring Boot & Microservices. Location: India (On-site). This role is being hired through Viraaj HR Solutions for client engagements requiring hands-on backend engineering and system ownership.

Role & Responsibilities
  • Design, develop and maintain Spring Boot microservices that expose secure, well-documented RESTful APIs.
  • Implement data persistence using JPA/Hibernate and optimize SQL queries for performance and scalability.
  • Collaborate with architects and product teams to translate requirements into robust, modular service designs and API contracts.
  • Deliver automated unit and integration tests, participate in peer code reviews, and uphold engineering best practices for quality and maintainability.
  • Containerize services and collaborate with DevOps to enable CI/CD pipelines, automated deployments, and environment provisioning.
  • Troubleshoot production incidents, perform performance tuning, and add observability (logs, metrics, traces) to support SLAs.
Skills & Qualifications
Must-Have
  • Proven experience building backend services in Java using Spring Boot and Spring ecosystem (Spring MVC/Security).
  • Practical knowledge of microservices architecture and designing RESTful APIs.
  • Experience with ORM frameworks: Hibernate / JPA and strong SQL skills for relational databases.
  • Experience containerizing applications with Docker.
  • Expertise in version control using Git and build tools such as Maven or Gradle.
  • Familiarity with writing unit and integration tests using JUnit and Mockito.
Preferred
  • Experience with Spring Cloud, service discovery, and distributed configuration.
  • Hands-on with Kubernetes, CI/CD pipelines (Jenkins/GitHub Actions/GitLab CI) and cloud platforms (AWS/Azure).
  • Knowledge of observability stacks (Prometheus, Grafana, ELK) and Chaos/Resilience patterns.
Benefits & Culture Highlights
  • Opportunity to work on greenfield and modernization projects that impact large-scale production systems.
  • Structured engineering practices: code review culture, test-driven development, and continuous delivery focus.
  • On-site collaboration with cross-functional teams—fast feedback loops and strong mentorship for technical growth.

How to apply: Candidates based in India who can work on-site and meet the technical criteria are encouraged to apply through Viraaj HR Solutions with an updated CV and portfolio of relevant projects or GitHub links.
