Role Overview


We are looking for a highly experienced Java Developer with 6–9 years of software development experience and strong expertise in designing and developing scalable, secure, and high-performance backend systems.

The ideal candidate should have deep hands-on experience with Java, Spring Boot, REST API development, database design, and backend integration. The candidate will be responsible for designing robust backend solutions, developing enterprise-grade services, integrating with internal and external systems, and providing technical leadership to engineering teams.

Key Responsibilities


  • Design, develop, and maintain scalable backend applications and services using Java and Spring Boot.
  • Define and drive backend design principles, coding standards, and engineering best practices.
  • Design and develop secure, reliable, and well-structured RESTful APIs.
  • Define API contracts, request/response models, error-handling mechanisms, and versioning strategies.
  • Design efficient and scalable relational and/or NoSQL database models.
  • Develop and optimize database queries, indexing strategies, and data-access layers.
  • Integrate backend applications with databases, third-party services, enterprise platforms, and external systems.
  • Design and implement backend integration patterns for reliable data exchange across systems.
  • Develop reusable backend components, libraries, and common services.
  • Ensure backend systems meet requirements for performance, scalability, availability, security, and maintainability.
  • Identify and resolve complex application, API, database, and integration-related issues.
  • Conduct code reviews and ensure adherence to software engineering and secure coding standards.
  • Collaborate with frontend developers, technical leads, product owners, QA engineers, DevOps teams, and other stakeholders.
  • Participate in technical design discussions, solution reviews, estimation, and implementation planning.
  • Mentor and provide technical guidance to backend developers.
  • Drive improvements in automated testing, build processes, CI/CD, deployment, and observability practices.

Required Technical Skills


  • 6–9 years of overall software development experience, with significant experience in backend application development.
  • Strong hands-on expertise in Java and object-oriented programming.
  • Strong experience with Spring Boot and the broader Spring ecosystem.
  • Strong experience in designing and developing RESTful APIs and backend services.
  • Good understanding of API design principles, HTTP standards, authentication, authorization, and error handling.
  • Strong experience in database design, data modeling, normalization, and performance optimization.
  • Experience with relational databases such as Oracle, PostgreSQL, MySQL, SQL Server, or equivalent technologies.
  • Strong proficiency in SQL and database query optimization.
  • Experience with ORM and persistence frameworks such as Spring Data JPA, Hibernate, or equivalent technologies.
  • Strong understanding of backend integration patterns and enterprise application integration.
  • Experience integrating applications with internal and external services through REST APIs, messaging, or other integration mechanisms.
  • Good understanding of concurrency, multithreading, asynchronous processing, and transaction management.
  • Experience developing modular, reusable, and maintainable backend components.
  • Strong understanding of application security and secure API development.
  • Familiarity with unit testing, integration testing, and automated testing frameworks.
  • Experience with source control systems such as Git.
  • Understanding of CI/CD pipelines and modern software development practices.

Preferred Skills


  • Experience working on large-scale enterprise applications and distributed systems.
  • Experience with microservices-based applications.
  • Knowledge of messaging technologies such as Kafka, RabbitMQ, JMS, or equivalent solutions.
  • Experience with caching technologies such as Redis or similar platforms.
  • Experience with API documentation tools such as OpenAPI/Swagger.
  • Knowledge of containerization technologies such as Docker and Kubernetes.
  • Experience with cloud platforms such as AWS, Azure, or Google Cloud.
  • Understanding of logging, monitoring, tracing, and observability practices.
  • Experience with automated testing frameworks such as JUnit, Mockito, or equivalent technologies.
  • Exposure to event-driven systems and asynchronous integration patterns.
  • Experience with Agile/Scrum software development environments.

Behavioral Competencies


  • Strong problem-solving and analytical skills.
  • Excellent communication and stakeholder-management skills.
  • Ability to translate business and system requirements into robust backend solutions.
  • Strong ownership and accountability for technical deliverables.
  • Ability to lead technical discussions and influence solution decisions.
  • Ability to work independently as well as collaboratively within cross-functional teams.
  • Strong mentoring and coaching capabilities.
  • Ability to troubleshoot complex backend, database, and integration issues.
