## Description

Citi is looking for a Lead API & Microservice Integration Engineer to serve as the Java Spring Boot subject matter expert and integration architect within the AI Automation Forward Deployed Engineering (FDE) team, part of Consumer Operations Technology. In this senior individual contributor role, you will design and deliver the API-first backbone that connects Citi\'s enterprise systems, data sources, and cloud-native services to our AI automation platforms. Working alongside a Lead AI/GenAI Engineer and Senior UI/Angular Engineer, you will ensure every intelligent solution is powered by robust, secure, and high-performance microservices built to the standards of a global financial institution., * Define and enforce the API-first strategy for the FDE organization, establishing OpenAPI/Swagger contract-first development practices, API versioning standards, and API gateway governance (routing, rate limiting, authentication) across all environments.

 * Lead hands-on design and delivery of production-grade Java Spring Boot microservices ? implementing resilient service patterns (Resilience4j circuit breakers, retry, bulkheads) and reactive services via Spring WebFlux for AI pipeline integrations.
 * Lead integration efforts with Citi enterprise systems including financial data platforms, identity/auth services (OAuth2/OIDC, SAML), and third-party providers; implement event-driven integration via Apache Kafka or IBM MQ for real-time data streaming to AI pipelines.
 * Partner with the Lead AI/GenAI Engineer to expose LLM inference, RAG pipeline, and agentic workflow endpoints as hardened, enterprise-ready Spring Boot services; collaborate with the UI Engineer to define and version all API contracts powering the Angular front-end.
 * Implement security-by-design across all microservices: mTLS, OAuth2/JWT authorization, secrets management (Vault), and field-level encryption ? ensuring compliance with Citi API governance, OWASP Top 10, SOX, and GDPR requirements.
 * Build full observabilities for all services ? distributed tracing (OpenTelemetry), structured logging (Splunk/ELK), and metrics/alerting (Prometheus, Grafana) ? and lead performance engineering via load testing (Gatling, k6) against defined SLAs.
 * Collaborate with DevOps and platform teams to build CI/CD pipelines and define Helm charts/Kubernetes manifests for zero-downtime deployments across OpenShift containerized platforms., At Citi, you will work within the AI Automation Forward Deployed Engineering (FDE) team in Consumer Operations Technology, sitting at the intersection of enterprise engineering and AI innovation. This is a high-impact role with real ownership, technical influence, and the opportunity to collaborate with experts across AI, front-end, and platform engineering at global scale.
 * A hybrid working model with 3 days in the office and 2 days working remotely, giving you flexibility alongside meaningful in-person collaboration.
