Job description
Citi, the leading global bank, has approximately 200 million customer accounts and does business in more than 160 countries and jurisdictions. Citi provides consumers, corporations, governments, and institutions with a broad range of financial products and services, including consumer banking and credit, corporate and investment banking, securities brokerage, transaction services, and wealth management.
The Applications Development Technology Lead Analyst (Lead Java Developer) is a senior‑level position responsible for leading the architectural design, implementation, and continuous modernization of robust, highly available, and scalable enterprise application systems. This role combines hands‑on engineering in modern Java ecosystems (Java 17+, Spring Boot, Kafka, Cloud Native) with technical team leadership, architectural governance, and leveraging modern AI‑assisted engineering tools to drive developer productivity.
- Act as the technical lead and mentor for an agile development pod; conduct thorough code reviews, enforce engineering standards, and coach engineers in modern design patterns and clean code principles.
- Drive sprint technical planning, work allocation, backlog grooming, and technical risk assessment in partnership with Product Owners and Project Managers.
- Champions continuous improvement by adopting modern engineering methodologies, test‑driven development (TDD), and GenAI‑powered developer productivity tools (e.g., GitHub Copilot) to accelerate delivery and enhance code quality.
- Lead the end‑to‑end design and delivery of resilient, cloud‑native microservices architectures using Java 17+ and Spring Boot (3.x).
- Architect high‑throughput, low‑latency event‑driven systems utilizing Apache Kafka (topic partitioning, consumer group management, schema registries, and idempotent processing).
- Design and optimize relational persistence layers on Oracle Database, including complex data modeling, schema migrations (Flyway/Liquibase), advanced query tuning, index optimization, and transaction management via JPA/Hibernate.
- Establish secure, robust RESTful APIs and asynchronous integration endpoints adhering to enterprise security standards and API governance.
- Drive containerization and deployment strategies using Docker, Kubernetes, and Red Hat OpenShift across hybrid and enterprise cloud environments.
- Define and implement scalable deployment manifests, Helm charts, health check probes, horizontal pod autoscaling (HPA), and zero‑downtime deployment strategies (blue‑green / canary).
- Partner with DevOps teams to enhance automated CI/CD pipelines (Git, Jenkins/Tekton, SonarQube, Artifactory, Snyk) with automated quality gates and security scans.
- Promote rigorous automated testing practices, establishing high test coverage with JUnit 5, Mockito, integration testing (Testcontainers), and contract testing.
- Implement comprehensive telemetry, centralized logging, distributed tracing, and monitoring using tools such as Prometheus, Grafana, OpenTelemetry, and Splunk/Loki.
- Resolve complex, high‑impact production and performance bottlenecks through heap/thread dump analysis, JVM tuning, and profiling.
- Appropriately assess risk when business decisions are made, demonstrating particular consideration for the firm's reputation and safeguarding Citigroup, its clients, and assets.
- Ensure strict adherence to secure software development lifecycle (SSDLC) practices, regulatory standards, vulnerability management, and architecture governance policies.
- 6+ years of professional experience in software engineering and enterprise applications development.
- Java 17+ Expertise: Deep hands‑on experience with modern Java (Java 17/21), including records, sealed classes, pattern matching, concurrency/multi‑threading, memory management, and modern garbage collectors (G1, ZGC).
- Spring Framework & Microservices: Extensive experience designing and building enterprise microservices with Spring Boot 4.x, Spring Cloud, Spring Data JPA, Spring Security, and distributed caching.
- Event‑Driven Architecture & Messaging: Proven track record implementing scalable streaming solutions using Apache Kafka (producers/consumers, error handling, dead‑letter queues, Avro/JSON schema registry).
- Database & Data Modeling: Strong proficiency in Oracle Database (SQL, PL/SQL, query execution plan analysis, indexing strategies, connection pooling, and performance optimization).
- Cloud & Container Ecosystem: In‑depth knowledge of Docker, Kubernetes, and Red Hat OpenShift (deployments, services, configs/secrets, ingress, pod lifecycle, Helm).
- AI‑assisted Development: Experience utilizing AI developer tools (e.g., GitHub Copilot, AI‑driven code generation, automated test scaffolding, and refactoring assistants) to enhance engineering velocity and team efficiency.
- Testing & Quality Assurance: Advanced experience with JUnit 5, Mockito, Testcontainers, mutation testing, and static analysis tools (SonarQube, Checkmarx).
- Build & CI/CD Tooling: Proficient with Maven/Gradle, Git, Jenkins/Tekton pipelines, and modern DevOps release management.
- Demonstrated experience acting as a technical team lead, scrum tech lead, or lead engineer guiding engineering teams.
- Strong analytical and problem‑solving skills with the ability to navigate ambiguous, complex legacy systems into modern target states.
