Job description

• Core Tech Stack: Core Java, Spring Boot, Apache Kafka, Oracle RDBMS (PL/SQL)


• Bonus Tech: React (Modern Frontend Ecosystem)


• Role Focus: High-throughput backend engineering, relational data modeling, and intentional system design.

Must-Have Backend Expertise

• Core Java: Deep comprehension of concurrency models, memory management (JVM tuning), generics, Collections framework, and functional paradigms introduced in Java 8+.


• Spring Ecosystem: Comprehensive experience with Spring Boot, Spring Data, Spring Security, and Spring Cloud. Must be able to explain how dependency injection functions at a runtime level.


• Distributed Messaging: Production experience using Apache Kafka. You should understand partitioning strategies, retention policies, replication factors, and delivery guarantees (at-least-once vs. exactly-once).


• Relational Databases: Exceptional Oracle SQL and PL/SQL skills. Proven capability in debugging locks, understanding isolation levels, and optimizing complex joins or batch processing jobs.

Must-Have Design Metrology

• Mastery of SOLID principles and classic Gang of Four (GoF) design patterns.


• Experience architecting microservices with distributed communication vulnerabilities in mind (handling partial failures, retries, and dead-letter queues).

Nice-to-Have (The Accelerator)

• Frontend Ecosystem: Practical experience with React, state management libraries (Redux, Context API), and modern build tools (Webpack, Vite). Comfortable managing state synchronization between client and server.
