Core Responsibilities

Microservices Development: Architect, build, and maintain scalable, high-throughput microservices leveraging Java, Spring Boot, and cloud-native design patterns.
API & System Integration: Design, implement, and consume secure, highly performant RESTful APIs to integrate internal platforms with external enterprise systems.
Data & Messaging Orchestration: Optimize application interactions with relational databases and event-driven architectures utilizing distributed messaging systems.
Code Quality & Reliability: Lead by example through robust unit testing, system integration testing, strict code reviews, and proactive application performance tuning.
CI/CD & DevOps Alignment: Implement and support continuous integration and deployment pipelines to ensure rapid, secure production releases.

Required Technical Skills

Experience: 6–10 years of progressive, hands-on enterprise software engineering experience.
Core Java Mastery: Elite proficiency in Core Java, including modern language features (Java 8, 11, and 17).
Spring Ecosystem Expertise: Deep, production-grade knowledge of Spring Boot, Spring MVC, Spring Security, and Spring Data JPA.
Distributed Architecture: Proven experience designing and operating Microservices Architectures and handling distributed transactions.
Databases & Messaging: Strong command of SQL databases (PostgreSQL, Oracle, or SQL Server) alongside event streaming/messaging tools (Kafka, RabbitMQ, or JMS).
Foundational Engineering: Complete fluency in Git-based workflows, Unix/Linux environments, and Object-Oriented Design Patterns.
