Job description

Role Overview:

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.

Qualifications & Skills:

Required Technical Qualifications:

• 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, TypeScript, 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 and mocking frameworks (JUnit, Mockito, Jasmine, Karma, or Jest).

• Build & CI/CD Tools: Familiarity with Git/Bitbucket, Maven/Gradle, Jenkins, Docker, and standard deployment automation tools.

Preferred / Nice-to-Have Qualifications:

• Prior domain knowledge in Hedge Fund operations, Fund Administration, Institutional Billing, Asset Management, or Capital Markets.

• Familiarity with Cloud platforms (Red Hat OpenShift).

• Experience with ORM frameworks (Hibernate/JPA) and batch processing (Spring Batch).

Professional & Behavioral Competencies:

• Ownership & Accountability: Proactive attitude with a demonstrated ability to manage features from inception through production release.

• Problem Solving under Pressure: Proven track record of managing competing priorities, meeting delivery milestones, and adapting to shifting business requirements.

• Communication & Collaboration: Excellent oral and written communication skills with the ability to explain complex technical concepts clearly to both technical peers and non‑technical business stakeholders.

• Agile Mindset: Experience working effectively within geographically dispersed, cross‑functional Agile/Scrum squads.
