POSITION OVERVIEW

Develop and maintain scalable backend services using Java, Go, and React with integrated messaging systems. Build robust microservices architectures with high-performance queue processing and real-time data handling capabilities for enterprise applications.

KEY RESPONSIBILITIES

• Backend Development: Build and maintain backend services using Java Spring Boot and Go for microservices architectures. Develop RESTful APIs, GraphQL endpoints, and event-driven systems that support high-traffic applications with seamless frontend integration.
• Middleware Implementation: Design and implement message queue systems using Kafka, RabbitMQ, Redis, and other messaging technologies. Handle asynchronous processing, event streaming, and inter-service communication in distributed systems.
• Database Development: Work with PostgreSQL, MongoDB, and caching systems to ensure optimal data storage and retrieval. Implement database optimization techniques, connection pooling, and data modeling best practices.
• System Performance: Optimize application performance through efficient coding practices, concurrent programming in Go, database query optimization, and caching strategies to ensure sub-second response times.
• Design and develop backend microservices using Java (Spring Boot) and Go (Golang), following SOLID principles and modular coding practices.
• Implement RESTful APIs and gRPC services to power both internal tools and customer-facing applications with clear versioning and documentation.

TECHNICAL REQUIREMENTS

• Core Programming: Strong proficiency in Java with Spring Boot framework and Go programming language. Experience with concurrent programming, goroutines, channels, multithreading, and modern Java features.
• Messaging & Queues: Hands-on experience with Apache Kafka, RabbitMQ, Redis, and message broker technologies. Understanding of event-driven architectures, stream processing, pub/sub patterns, and distributed messaging.
• Database Skills: Proficiency with PostgreSQL and MongoDB including query optimization, indexing, transactions, and database design. Experience with ORM frameworks like Hibernate, GORM, and database migration tools.
• Development Tools: Experience with Docker containerization, Git version control, Maven/Gradle build tools, unit testing frameworks (JUnit, Go testing), and CI/CD pipeline integration.
• API Development: Strong experience designing and implementing REST APIs, understanding of HTTP protocols, API authentication, rate limiting, and documentation using tools like Swagger/OpenAPI.

EXPERIENCE & QUALIFICATIONS

• Professional Experience: 3-4+ years in backend development with 2+ years using Java Spring ecosystem, 1+ year with Java, and working knowledge of React for full-stack integration.
• Technical Expertise: Proven experience with microservices architecture, distributed systems, message queues, and database technologies in production environments. Understanding of software engineering best practices and design patterns.
• Education: Bachelor's degree from Top Tier Institutes in Computer Science, Software Engineering, or related technical field. Strong foundation in data structures, algorithms, and computer science fundamentals.
• Collaboration Skills: Experience working in agile development environments, collaborating with cross-functional teams, conducting code reviews, and contributing to technical documentation and knowledge sharing.
• Strong problem-solving skills, attention to detail, and a proactive approach to code quality.
