Senior Java Microservices Developer

Microservices Design & Development Design and develop scalable, cloud-native microservices using   Java (17/21)   and the   Spring Boot   framework. Utilize the   Helix Platform   to build, package, and deploy standalone components, reusable blueprints, and serverless   Knative Functions . Ensure clean code architecture, adhering to enterprise design patterns, SOLID principles, and RESTful API standards. Cloud Orchestration & Service Mesh Deploy, manage, and scale microservices on   Red Hat OpenShift Container Platform (OCP)   and Kubernetes. Configure and manage service-to-service communication, traffic routing, and observability using   Service Mesh   (Istio-based control plane). Define and maintain   Helm charts   for consistent, repeatable application deployments across environments.Database Integration & Management Integrate microservices with Citi's   Database as a Service (DBaaS)   platform. Work with relational and non-relational databases, including: PostgreSQL as a Service (PGaaS)   (utilizing PG Vector for advanced search capabilities). MongoDB as a Service (MaaS)   (leveraging multi-datacenter high availability and sharding). Oracle as a Service (OraaS)   (ensuring high-availability and automated scaling). Security & Secret Management Implement robust application security and credential management using   HashiCorp Vault . Configure and manage Vault roles (Kubernetes ServiceAccounts, AppRoles, and PKI roles) to secure application secrets. Utilize   Vault Agent   sidecars in Kubernetes/OpenShift to dynamically inject and render secrets into application pods. CI/CD & DevOps Automation Build and maintain automated CI/CD pipelines using   Lightspeed Enterprise   (Tekton and Harness) and   Lightspeed Classic   (Jenkins shared libraries and uDeploy). Integrate automated quality and security gates into the build process, including   SonarQube   for code quality,   Checkmarx   for static analysis, and   Snyk   for vulnerability scanning. Manage source code repositories using   Bitbucket   and   GitHub Enterprise , adhering to branch protection rules and pull request workflows. Required Technical Skills & Qualifications Education:   Bachelor’s degree in Computer Science, Engineering, or a related technical field. Java Expertise:   5+ years of professional software development experience with   Java (17 or higher)   and   Spring Boot / Spring Cloud . Containerization:   Strong experience with   Docker ,   Kubernetes , and   Red Hat OpenShift (OCP) . Service Mesh:   Hands-on experience with   Istio   or equivalent Service Mesh technologies for traffic management and observability. Database Systems:   Proficiency in SQL and NoSQL databases, specifically   PostgreSQL ,   MongoDB , and   Oracle . Security:   Experience with   HashiCorp Vault   (secret engines, Vault Agent, and role-based access control). CI/CD Tools:   Experience with modern CI/CD platforms such as   Tekton ,   Harness ,   Jenkins , and   uDeploy . Testing & Quality:   Strong commitment to quality, with experience in   JUnit ,   Mockito ,   SonarQube , and security scanning tools ( Snyk ,   Checkmarx ).
