Java Developer

We are seeking an experienced Java Developer (57 years) with strong expertise in Core Java 8+, Spring Boot, REST APIs, Microservices, and database-driven backend development. The ideal candidate should be well-versed in building scalable, secure services and integrating with distributed systems. Exposure to AWS, DevOps, Kafka, and service virtualization tools is a strong advantage.

Key Responsibilities

Backend Development

Develop and enhance scalable backend services using Java 8+ and Spring Boot.

Build secure, high-quality RESTful APIs with proper validation, exception handling, and authentication/authorization.

Microservices Architecture

Implement microservices with best practices for service registry, configuration management, resiliency patterns (retry, circuit breaker), and asynchronous communication.

Ensure services are modular, fault-tolerant, observable, and optimized for performance.

Database Development

Work with relational/NoSQL databases: MySQL, PostgreSQL, Oracle, MongoDB.

Write optimized SQL queries, manage transactions, indexing, and database performance tuning.

Code Quality & Reviews

Write clean, testable, maintainable code using OOP, SOLID principles, and design patterns.

Conduct peer code reviews and participate in architecture and design discussions.

Cloud & DevOps Collaboration

Deploy and maintain applications on AWS (S3, EC2, RDS, IAM, CloudWatch, etc.).

Collaborate with DevOps teams on CI/CD pipelines, containerization (Docker), and automated deployments.

Testing & Quality Assurance

Write strong unit tests using JUnit, Mockito and ensure high code coverage.

Support integration testing, debugging, and issue resolution across environments.

Service Virtualization & Integrations

Use tools like WireMock, MockServer, or similar for service virtualization to simulate dependent systems.

Required Skills (Primary)

Core Java (8+)

Strong understanding of OOPs, Collections, Streams, and Lambda expressions.

Familiarity with features from Java 11, 17, and 21 (switch expressions, var, records, virtual threads, pattern matching, etc.).

Spring Boot

Strong experience with Spring Boot modules, annotations, configuration, and application lifecycle.

Hands-on with Spring Web, Spring Data JPA, Spring Validation, Spring Security, and monitoring tools.

REST API Development

Deep understanding of REST architecture, pagination, versioning, idempotency, and API documentation (Swagger/OpenAPI).

Microservices

Good understanding of distributed systems, async messaging, logging/tracing (ELK, Prometheus, Loki, Grafana), and microservice best practices.

Database

Strong SQL and experience with relational database design, optimization, indexing, and ORMs (Hibernate/JPA).

Hands-on Coding

Ability to independently design, develop, debug, test, and deploy features end-to-end.

Secondary Skills (Good to Have)

Cloud AWS (Preferred)

Experience with EC2, S3, IAM, Lambda, CloudWatch, ECS/EKS.

DevOps

Familiarity with CI/CD pipelines: Jenkins, GitLab CI, GitHub Actions.

Experience with Docker and containerization.

Kafka

Understanding of event-driven architecture, producers/consumers, topics, partitions, and offset management.

Unit Testing

Strong skills in JUnit, Mockito; exposure to TDD/BDD is a plus.

Service Virtualization

Experience with WireMock, MockServer, or similar tools.

Soft Skills

Strong analytical and problem-solving mindset.

Ability to work in Agile teams and collaborate cross-functionally.

Excellent communication and documentation skills.

Ownership-driven attitude with a willingness to learn new technologies.
