Senior Java Developer / Software Engineer (Junior - Senior Openings)

About the Opportunity

We are actively hiring for Java Software Engineering and Backend Developer positions across multiple experience tiers.

• System Design & Architecture: Design, build, and maintain robust, high-throughput backend services using Java, Spring Boot, and Spring Cloud microservices architecture.
• Next-Gen AI Integration (Senior Focus): Build intelligent services, explore LLM integrations, and independently design and deploy autonomous AI Agents within core business applications.
• Database & Performance Optimization: Architect and tune complex database structures and queries across PostgreSQL, MySQL, and Oracle, eliminating bottlenecks via indexing and query optimization.
• Distributed Resilience & Messaging: Integrate distributed messaging middleware (Kafka, RabbitMQ) to ensure message consistency, reliability, and asynchronous processing.
• End-to-End Delivery & Maintenance: Work across the full SDLC in Agile/Scrum sprints, supporting code analysis, bug diagnostics, CI/CD delivery, and operational resilience.
