• Manage and optimize Kafka infrastructure, including topics, partitions, and consumer groups to ensure high availability and fault tolerance.
• Collaborate with architects and technical leads to define and refine system architecture, ensuring the scalability, resilience, and high availability of our microservices ecosystem.
• Design and optimize MongoDB schemas, indexing strategies, and aggregation pipelines for efficient data storage and retrieval.
• Write clean, maintainable, and well-documented code, adhering to industry best practices and established design patterns.
• Champion code quality by performing thorough code reviews, implementing comprehensive testing strategies (unit, integration, and end-to-end), and mentoring junior developers.
• Work with DevOps teams to implement and manage CI/CD pipelines for automated builds, testing, and deployments in cloud environments (e.g., AWS, Red Hat OpenShift).
• Utilize containerization tools like Docker and orchestration platforms like Kubernetes for deploying and managing applications.
• Collaborate closely with product managers, business analysts, and other cross-functional teams to translate complex business requirements into technical solutions.
• Proactively monitor application performance, troubleshoot, and resolve production issues in a timely and efficient manner.

Qualifications

• 6+ years' professional experience in Java development with a strong emphasis on building backend, distributed systems.
• Expert-level proficiency in the Spring Framework, including Spring Boot, Spring MVC, Spring Data, and Spring Security.
• Extensive hands-on experience designing, building, and maintaining a microservices architecture and creating RESTful APIs.
• Deep expertise in Apache Kafka, including its architecture (topics, partitions, replication), and practical experience developing producers, consumers, and stream processing applications.
• Strong proficiency with MongoDB, including data modeling, schema design, indexing, and writing efficient aggregation pipelines.
• Hands-on experience with containerization technologies such as Docker and container orchestration with Kubernetes.
• Experience with deploying and managing applications on cloud platforms (e.g., AWS, Azure, GCP).
• Proven experience with CI/CD principles and tools like Jenkins, GitLab CI/CD, or GitHub Actions.
• Solid understanding of object-oriented programming (OOP) principles and software design patterns.
