Java Developer, Finance Engine Hedge Fund Billing, Assistant Vice President

Citi is seeking a highly motivated Senior Software Engineer to join the Finance Engine Hedge Fund Billing technology team.

In this role, you will be instrumental in designing, building, and enhancing high-throughput, enterprise-grade billing and calculation engines that serve institutional hedge fund clients globally.

The Hedge Fund Billing platform is a mission-critical financial system that handles complex fee structures and high-volume transactional processing across multiple business lines.

• Design, develop, test, deploy, and maintain robust full-stack applications leveraging Java microservices and modern Angular frontends.
• Architect modular, extensible services capable of performing high-volume calculations.
• Develop interactive, intuitive user interfaces and operational dashboards in Angular, ensuring seamless user experience, state management, and performance.
• Write clean, well-documented, testable, and maintainable code adhering to Citi's engineering standards and design patterns.

• Design efficient relational database schemas, complex SQL queries, stored procedures, indexing strategies, and views for high-performance financial data processing.
• Profile and optimize backend queries and API performance to ensure low-latency data retrieval and reliable processing of large billing datasets.
• Ensure data integrity, transactional consistency (ACID compliance), and auditability across all financial accounting workflows.

• Take full end-to-end ownership of the software lifecycle—from requirement analysis and technical design to implementation, automated testing, deployment, and post-release support.
• Drive iterative delivery using Agile/Scrum methodologies, collaborating with cross-functional teams in sprint planning, backlog grooming, and demos.
• Champion test-driven development (TDD) and automated testing across unit, integration, and end-to-end testing frameworks (JUnit, Mockito, Jasmine/Karma, Cypress).

• Integrate automated builds, static code analysis (Sonar Qube), vulnerability scanning, and automated deployments into enterprise CI/CD pipelines (Jenkins, Bitbucket, Harness, or similar).
• Participate in platform modernization initiatives, including containerization (Docker, Open Shift/Kubernetes) and cloud-ready architectural enhancements.

• Partner with Level 3 Application Support and Dev Ops teams to diagnose and remediate production issues, conduct root-cause analyses (RCA), and implement preventive fixes.
• Implement comprehensive monitoring, alerting, health checks, and structured logging (Prometheus, Grafana, Splunk/ELK) to maintain high availability.

• Experience:
  
  5–8 years of professional hands‑on software development experience building enterprise-scale distributed systems (experience in Financial Services is a must).
• Java Expertise:
  In-depth knowledge of Core Java, JVM internals, concurrency, multi-threading, Spring Framework, Spring Boot, and RESTful API architecture.
• Angular Expertise:
  Strong proficiency in modern Angular, Type Script, HTML5/CSS3, responsive UI design, and single-page application (SPA) architecture.
• Database & SQL:
  Extensive experience with relational databases (Oracle, PostgreSQL, MS SQL, or Sybase), complex query tuning, schema design, and transaction management.
• Microservices & Messaging:
  Practical experience with microservices architecture, REST/JSON APIs, and message brokers/event streaming (e.g., Apache Kafka, RabbitMQ, or JMS).
• Testing & Quality:
  Solid foundation in unit testing…
