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.

You will work closely with product managers, business analysts, and technical leads to deliver scalable, resilient, and cloud-ready full-stack solutions using Java, Angular, and MSSQL technologies.

Key Responsibilities

1. Architecture, Design & Full-Stack Engineering

• 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.

2. Database Engineering & Performance Optimization

• 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.

3. End-to-End Code Ownership & Delivery

• 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).

4. DevOps, CI/CD & Modernization

• Integrate automated builds, static code analysis (SonarQube), vulnerability scanning, and automated deployments into enterprise CI/CD pipelines (Jenkins, Bitbucket, Harness, or similar).

• Participate in platform modernization initiatives, including containerization (Docker, OpenShift/Kubernetes) and cloud-ready architectural enhancements.

5. Production Support & Operational Excellence

• Partner with Level 3 Application Support and DevOps 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.
