Requirements
Minimum 8 years of active, hands‑on Java development – candidates must demonstrate current, working proficiency, not experience from several years ago.
Strong, up‑to‑date expertise in Java OOP principles, concurrency, and modern Java features; recent and regular practice is essential.
Proven, current hands‑on experience with Spring Boot – candidates must be able to build and discuss Spring Boot applications confidently during technical evaluation.
Real‑world coding experience in microservices architecture – candidates must be able to describe actual implementations and write microservices code; conceptual understanding alone is not sufficient.
Solid practical knowledge of Apache Kafka in a production setting, including producing, consuming, and managing topics – basic or introductory exposure will not meet the requirement.
Experience working in Agile / Scrum delivery environments.
Good communication skills and ability to collaborate effectively with onsite and distributed teams.
Responsibilities
Design, develop, and maintain scalable backend services using Java and Spring Boot.
Build and evolve microservices within a distributed systems architecture.
Develop and maintain Kafka‑based event‑driven pipelines.
Conduct and participate in code reviews to uphold code quality standards.
Collaborate with architects, product owners, and cross‑functional teams to deliver features end‑to‑end.
Contribute to technical documentation, design decisions, and best practices.
