Descrizione del lavoro

Citi is looking for a Java & Microservices Developer - AVP to build mission-critical, distributed backend systems that power financial transactions on a global, 24x7 scale. In this role, you will provide technical leadership for high-throughput, low-latency platforms that support real-time Payments processing. You will drive cloud-native Java microservices using Spring Boot, Kafka, and modern AI-accelerated engineering practices (AI-PDLC, GitHub Copilot, Devin), directly shaping the reliability, performance, and 99.999% availability of critical platforms. You will partner with product managers, enterprise architects, and cross-functional engineering squads to translate complex business and regulatory requirements into robust, production-ready solutions.

Responsibilities

Build high-throughput, low-latency Java microservices for 24x7 real-time transaction processing, applying core patterns to ensure zero data loss and uninterrupted availability.
Build event-driven streaming and messaging architectures using Apache Kafka
Champion and institutionalize the AI-Assisted Product Development Lifecycle (AI-PDLC) across engineering squads, leveraging generative AI developer tools and autonomous agents (such as GitHub Copilot, Devin, and AI-driven automated testing/code review tools) to accelerate delivery velocity while enforcing firmwide security and governance standards.
Construct resilient cloud-native services utilizing Spring Boot and Spring Cloud components, establishing centralized configuration management, service discovery, distributed tracing, and mTLS security for financial service-to-service communication.
Implement modern financial messaging standards and payment protocols, including ISO 20022 (pacs, pain, camt), real-time payment schemes, and industry-standard financial networks, ensuring strict alignment with data security standards and cryptographic controls.
Optimize data access and persistence tiers across distributed SQL and in-memory caching solutions to maximize throughput and achieve sub-millisecond execution times.
Apply deep expertise in core Java concurrency, Virtual Threads, memory management, and JVM garbage collection tuning to deliver ultra-performant, thread-safe backend architectures.
Partner with Site Reliability Engineering (SRE) to establish observability standards (OpenTelemetry, Prometheus, Grafana, Splunk) and lead performance profiling, chaos engineering experiments, and volume stress testing across all transaction paths.
Lead technical design reviews and code reviews, providing mentorship and architectural guidance that elevates engineering excellence, code quality, and security posture across multiple squads.
Guide containerized workload deployment and management on Docker and Kubernetes / OpenShift, supporting modern CI/CD automation and zero-downtime deployment strategies.

Required qualifications & skills

Hands-on Java software engineering experience of 8+ years, with deep proficiency in Java 17/21, concurrency utilities, Virtual Threads, memory management, and advanced JVM performance tuning.
Demonstrable track record of designing, developing, and operating production-grade microservices using Spring Boot, Spring Cloud, and reactive programming paradigms.
Deep expertise in event streaming and messaging architectures using Apache Kafka or RabbitMQ, with practical mastery of partitioning strategies, distributed transactions, and idempotency patterns.
Practical mastery of microservices architecture patterns including API Gateway, SAGA, CQRS, Event Sourcing, Transactional Outbox, Circuit Breaker, and Service Discovery.
Hands-on experience integrating AI-assisted developer tools (e.g., GitHub Copilot, Devin, AI code analysis tools) and AI-PDLC practices into team delivery workflows.
Proficiency with containerization and orchestration platforms using Docker and Kubernetes / OpenShift in high-availability environments.
Competency with Git-based version control workflows, automated CI/CD pipelines, and Agile delivery methodologies (Scrum/Kanban).
Exceptional analytical, problem-solving, and communication skills, with the ability to influence cross-functional technical, product, and business leadership.
