Key Responsibilities:

1. Security Gateway & Java Microservice Development

• Java Application Engineering: Develop, test, and maintain high-performance, resilient microservices using Java (Java 11/17+), Spring Boot, Spring Security, and RESTful APIs.
• Security Gateway Implementations: Support reverse-proxy and gateway integrations (e.g., PingAccess, OpenShift/ECS container services) to secure Green Network (GRN) enterprise application traffic.
• Authentication & Federation Support: Assist in implementing modern authentication protocols (SecureSSO, OIDC, OAuth 2.0, COIN tokens) and participate in migrating legacy security protocols (e.g., SiteMinder to OIDC/COIN).
• API Routing & Fault Tolerance: Configure and maintain routing downstream from API Gateways (Apigee / APIM), integrating service discovery (Eureka/CCP) and implementing resilience patterns (resilience4j/circuit breakers, retries, and rate limiters).

2. Software Lifecycle, Quality & Code Execution

• Full Development Lifecycle: Participate actively in all phases of the Agile SDLC (sprint planning, daily standups, backlog refinement, and retrospectives).
• Code Quality & Testing: Write clean, modular, and maintainable Java code adhering to SOLID principles; build comprehensive unit, integration, and contract tests utilizing JUnit, Mockito, and test containers.
• Root Cause Analysis & Defect Remediation: Investigate, debug, and resolve application bugs, performance bottlenecks, and runtime errors in non-production and production environments.
• CI/CD & DevOps Integration: Build and manage automated build/deploy pipelines using Git, Maven/Gradle, and enterprise CI/CD tools (e.g., Tekton/Lightspeed, Bitbucket/GitHub, OpenShift).

3. Security, Risk & Collaboration

• Secure Coding & Vulnerability Remediation: Ensure all developed code complies with enterprise security benchmarks (SonarQube, Snyk, Checkmarx, MCD scans) and remediate identified vulnerabilities promptly.
• Peer Reviews & Collaboration: Actively participate in peer code reviews, contribute to technical documentation, and collaborate effectively with quality assurance, architecture, and platform operations teams.
• Risk & Controls Adherence: Adhere to Citi’s technology risk and governance policies, applying sound judgment to safeguard firm assets and data.

• Solid understanding of REST APIs, HTTP/HTTPS protocols, mutual TLS (mTLS), and web security standards (OWASP Top 10).
• Working knowledge of authentication/authorization protocols such as OAuth2, OpenID Connect (OIDC), JWT, and SAML.
• Practical experience working with containerized environments (Docker, Kubernetes / Red Hat OpenShift).
• Experience with relational/NoSQL databases, SQL querying, and database connection pooling.
• Hands-on experience with automated testing tools (JUnit, Mockito) and CI/CD tools (Git, Maven/Gradle, Jenkins/Tekton).
• Good problem-solving, analytical, and debugging skills with distributed systems.
