Key Responsibilities
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 Enterpri
