Java Spring Microservices
Zensar Technologies Chennai, Tamil Nadu, India
Job Description
"Unlock the power of modern software development with Java Spring Microservices at Zensar Technologies."
In this role, you will design, develop, and maintain high-performance Java-based RESTful APIs and microservices that serve member-facing digital products.
You will be responsible for building and evolving the core Member Services platform capabilities, including account management, card servicing, rewards, benefits inquiry, and transaction history.
Why you should learn this:
The demand for Java Spring Microservices developers is high in the current market, with a growing need for cloud-native, event-driven architectures.
Expected Salary: $120,000 - $180,000 per annum, depending on experience and location.
How it works:
- Design loosely coupled, independently deployable microservices using Java Spring Boot and Spring Cloud.
- Develop event-driven architectures using Apache Kafka for real-time member data processing, notifications, and service orchestration.
- Implement GraphQL APIs to support flexible, efficient data delivery to mobile and web front-end clients.
- Ensure API contracts are robust, versioned, well-documented, and backward-compatible across consumer teams.
Core Concepts to Master
Spring Boot
Spring Boot is a popular framework for building standalone, production-grade Spring-based applications. It provides a simple way to create web applications, RESTful APIs, and microservices using Java.
Spring Cloud
Spring Cloud is a suite of tools for building cloud-native applications using Java. It provides features such as service discovery, circuit breakers, and load balancing, making it easier to build scalable, resilient microservices.
Apache Kafka
Apache Kafka is a distributed streaming platform that enables real-time data processing, notifications, and service orchestration. It provides a scalable, fault-tolerant way to handle high-throughput data streams.
GraphQL
GraphQL is a query language for APIs that allows clients to specify exactly what data they need, reducing the amount of data transferred and improving performance. It provides a flexible, efficient way to deliver data to mobile and web front-end clients.
Microservices Architecture
A microservices architecture is a design approach that structures an application as a collection of small, independent services that communicate with each other using APIs. It provides a scalable, flexible way to build and maintain complex systems.
