They will lead the technical vision and guide the development team to create robust, cloud-native solutions.Responsibilities? Architecture Design: Define and implement the overall architecture of Java-based microservices applications, ensuring scalability, maintainability, and performance.? Microservices Development: Lead the development of microservices using Java, Spring Boot, and potentially reactive frameworks like Spring WebFlux or Project Reactor.? Database Integration: Design and implement data models using MongoDB, ensuring efficient data storage and retrieval, and potentially explore NoSQL alternatives like Cassandra or DynamoDB.? Kubernetes Deployment: Manage the deployment and orchestration of microservices on Kubernetes, optimizing resource utilization and ensuring high availability, potentially using service meshes like Istio or Linkerd.? Oracle Cloud Integration: Utilize Oracle Cloud platform services (e.g., OCI Compute, OCI Database, OCI Container Engine for Kubernetes) to enhance application functionality and performance, potentially integrating with other cloud services like messaging queues or serverless functions.? Performance Engineering: Conduct thorough performance testing and optimization to ensure applications meet or exceed performance expectations, using tools like JProfiler, VisualVM, Gatling, or JMeter.? Technical Leadership: Mentor and guide developers, fostering a culture of technical excellence and continuous improvement, promoting best practices and code reviews.? Collaboration: Work closely with product managers, DevOps engineers, and other stakeholders to deliver high-quality solutions, participating in Agile ceremonies and ensuring alignment with business goals.Requirements? Expertise in Java: 8years of proven experience developing complex Java applications with a strong understanding of object-oriented design principles and expertise in Java 8features (streams, lambdas, etc.), including experience with testing frameworks like JUnit and Mockito? Microservices Architecture: Deep knowledge of microservices architecture patterns (e.g., Domain-Driven Design, CQRS, Event Sourcing) and best practices, with experience in API design (REST, GraphQL) and API gateways.? MongoDB Proficiency: Hands-on experience with MongoDB database design, implementation, and optimization, including data modeling, indexing, and aggregation, with potential exposure to other NoSQL databases.? Kubernetes Mastery: Experience managing containerized applications on Kubernetes, including deployment, scaling, and monitoring, with proficiency in Helm charts, Kubernetes networking concepts, and potentially experience with service meshes.? Oracle Cloud Familiarity: Exposure to Oracle Cloud platform services (e.g., OCI Compute, OCI Database, OCI Container Engine for Kubernetes) and their integration with Java applications, potentially including experience with other cloud providers (AWS, Azure, GCP).? Performance Engineering Skills: Demonstrated ability to identify and resolve performance bottlenecks in Java applications using tools like JProfiler, VisualVM, Gatling, or JMeter, with understanding of profiling and load testing techniques? Strong Leadership: Proven track record of leading technical teams and delivering successful projects, with experience in Agile methodologies and fostering a collaborative environment? Excellent Communication: Ability to clearly articulate technical concepts to both technical and non-technical audiences, with strong written and verbal communication skills.Preferred Qualifications? Experience with Spring Cloud or other microservices frameworks.? Familiarity with CI/CD pipelines and DevOps practices using tools like Jenkins, GitLab CI, or CircleCI? Experience with cloud-native monitoring and observability tools like Prometheus, Grafana, ELK stack, or Jaeger? Contributions to open-source projects or active participation in tech communities? Knowledge of security best practices and experience in implementing secure coding practices
