Job Summary:

We are seeking an accomplished Backend Engineer with 3 -10 years of experience in developing scalable, secure, and cloud-native backend systems. This role demands deep hands-on expertise in Java, Spring Boot, Spring Security, gRPC, PostgreSQL, Gradle, Docker, and Google Kubernetes Engine (GKE). You should have a solid grasp of various microservice design patterns, cloud infrastructure, and modern CI/CD pipelines.

You will lead end-to-end solution design and drive implementation of distributed systems that are resilient, observable, and easy to evolve. You will also work on security architecture, performance tuning, and designing robust communication strategies between services using REST and gRPC.

Key Responsibilities:

• Design, develop, and maintain high-performance backend services using Java (Spring Boot).
• Build and maintain gRPC-based APIs and services for real-time communication between microservices.
• Design REST API and rRPC services
• Manage and optimize Gradle build configurations.
• Containerize applications using Docker and deploy them on GKE (Google Kubernetes Engine).
• Write and maintain efficient, reusable, and reliable code with unit/integration tests.
• Use PostgreSQL for data storage, design schemas, and optimize queries.
• Set up and manage CI/CD pipelines using Jenkins.
• Monitor services and troubleshoot production issues using logs and metrics.
• Collaborate with frontend, QA, DevOps, and product teams to deliver high-quality features.

Required Skills & Qualifications

• Hands-on experience in backend software development using Java 11+ and Spring Boot.
• Proficient in Functional and Reactive Programming paradigms in Java.
• Solid understanding of Java multithreading and concurrent programming principles.
• Deep expertise in Spring Security, including implementation of custom security filter chains, authentication providers, and role-based access control.
• Strong background in designing extensible and maintainable codebases using design patterns such as Builder, Factory, and Strategy.
• Skilled in building and consuming gRPC services for efficient service-to-service communication.
• Extensive experience in containerizing applications with Docker and deploying them on Google Kubernetes Engine (GKE).
• Proficient in debugging and monitoring applications using Google Cloud Logging and Monitoring tools.
• In-depth knowledge of Gradle, including multi-module project setup, task customization, and dependency management.
• Strong command of PostgreSQL, with expertise in indexing, partitioning, and performance tuning.
• Well-versed in configuring and maintaining CI/CD pipelines using Jenkins, with a focus on automation and reliability.
• Solid grasp of distributed system architecture, RESTful API design, networking fundamentals, and applicationsecurity.
• Experienced in using observability tools and logs for troubleshooting production issues.
• Committed to writing efficient, reusable, and well-tested code, supported by thorough unit and integration testing.

Educational Qualifications:

Bachelor’s/master’s degree in computer science, Information Technology, or a related field.
