• *Location:** Primary Tech Hub / Hybrid

• *Role Overview**

Citi is seeking a highly skilled, passionate, and hands\-on **Senior Applications Development Engineer (VP level / Individual Contributor)** to drive core software development within the **Finance Engine – Hedge Fund Billing Technology** team.

In this hands\-on engineering role, you will be responsible for the end\-to\-end coding, implementation, optimization, and maintenance of high\-throughput, mission\-critical financial calculation engines and distributed microservices supporting global institutional hedge fund clients. This platform processes complex, tiered fee structures and high\-volume transactional workflows across multiple business lines, demanding ultra\-low latency, strict transactional integrity (ACID), high availability, and clean, resilient code design.

As a Senior Developer, your primary focus will be active coding, system design, query optimization, automated testing, and CI/CD deployment. You will work closely with lead architects, product analysts, and engineering peers to build robust full\-stack solutions, debug complex issues, refactor legacy components, and champion software craftsmanship across modern Java and Angular frameworks.

• *Key Responsibilities**

• *1\. Hands\-On Full\-Stack Development \& Microservices Engineering**

• **Core Application Development:** Write clean, modular, efficient, and well\-documented code across distributed Core Java / Spring Boot microservices and modern Angular SPAs.
• **Calculation Engine Implementation:** Implement and maintain high\-throughput financial calculation logic, fee algorithms, and multi\-asset billing workflows requiring low\-latency execution and high concurrency.
• **API \& System Integration:** Design, develop, and consume secure, robust RESTful APIs and asynchronous event\-driven messaging pipelines (Kafka / RabbitMQ / JMS).
• **Refactoring \& Modernization:** Actively contribute to legacy code modernization, containerization (Docker, OpenShift / Kubernetes), and framework upgrades to maintain modern architectural standards.
• **Debugging \& Problem Solving:** Deep\-dive into complex runtime issues, thread contention, memory leaks, and distributed transaction bottlenecks to deliver rapid, permanent technical fixes.

• *2\. Database Development \& Query Optimization**

• **Schema Design \& SQL Engineering:** Develop and optimize complex SQL queries, stored procedures, table schemas, and indexing strategies on relational databases (MSSQL, Oracle, or PostgreSQL).
• **Data Integrity \& Consistency:** Ensure strict transactional integrity (ACID compliance), robust error handling, and auditable financial data processing across high\-volume batch and real\-time streams.
• **Performance Tuning:** Conduct database profiling, execution plan analysis, and query tuning to eliminate batch bottlenecks and reduce processing times.

• *3\. Software Quality, Automated Testing \& DevOps**

• **Test Automation (TDD/BDD):** Write comprehensive unit, integration, and component tests using JUnit, Mockito, and relevant mocking frameworks to maintain high test coverage.
• **Code Quality \& Best Practices:** Adhere to enterprise static analysis standards (SonarQube) and participate actively in peer code reviews to maintain high coding standards and prevent vulnerabilities.
• **CI/CD \& Deployment Automation:** Build, maintain, and troubleshoot CI/CD pipelines (Bitbucket, Jenkins, Harness), automated build scripts, and container deployment manifests.
• **Production Support \& L3 Troubleshooting:** Partner with SRE and DevOps teams to triage Level 3 production issues, analyze logs and metrics (Splunk, Grafana, Prometheus), and implement permanent root\-cause fixes.

• *4\. Technical Collaboration \& Agile Execution**

• **Agile Sprint Delivery:** Actively participate in sprint planning, technical task estimation, daily standups, and backlog grooming.
• **Technical Specifications:** Translate user stories and functional requirements into detailed technical designs, class diagrams, and sequence flows.
• **Peer Collaboration:** Share technical knowledge, pair\-program on complex tasks, and collaborate constructively with squad members to meet sprint commitments.

• *5\. Risk, Security \& Regulatory Compliance**

• **Secure Coding:** Follow secure development lifecycle (SDLC) standards, remediate security vulnerabilities (SAST/DAST findings), and ensure data encryption/privacy protocols are rigorously maintained.
• **Audit \& Control Governance:** Ensure all deliverables adhere to Citi's software engineering governance, change management protocols, and risk controls.

• *Qualifications \& Skills:**

• *Required Technical Expertise \& Experience:**

• **Experience:** 6–10\+ years of hands\-on software development experience building enterprise\-scale distributed systems and transactional applications.
• **Core Java / JVM Mastery:** Deep hands\-on expertise in Core Java (Java 11/17/21\), JVM memory management, multi\-threading/concurrency, Spring Framework, Spring Boot, Spring Batch, and Hibernate/JPA.
• **Frontend Engineering:** Hands\-on experience developing single\-page applications (SPAs) using modern Angular, TypeScript, RxJS, HTML5, and CSS/SCSS.
• **Relational Database Expertise:** Strong hands\-on SQL programming and tuning experience across MSSQL, Oracle, or PostgreSQL (complex joins, CTEs, indexing, query execution plans).
• **Event Streaming \& Messaging:** Practical experience developing event\-driven producers/consumers using Apache Kafka, RabbitMQ, or JMS.
• **Containerization \& Tooling:** Working knowledge of Docker, Red Hat OpenShift / Kubernetes, Linux shell scripting, and Git/Bitbucket.
• **CI/CD \& Testing Frameworks:** Experience with Maven/Gradle, Jenkins, Harness, JUnit, Mockito, and SonarQube.

• *Preferred Qualifications:**

• Financial domain background in Hedge Fund Operations, Fund Administration, Institutional Billing, Asset Management, or Capital Markets.
• Familiarity with caching frameworks (Redis/Hazelcast) and observability tools (Splunk, ELK, Grafana, Prometheus).
• Experience with cloud platforms (AWS / GCP / Private Cloud environments).

• *Behavioral Competencies:**

• **Strong Problem Solver:** Passionate about writing clean, maintainable code and solving complex algorithmic/architectural challenges.
• **Execution \& Ownership:** Proven track record of independently taking technical tasks from design through production deployment.
• **Collaborative Mindset:** Strong team player with clear written and verbal technical communication skills.

• *Education**

• **Bachelor’s degree** in Computer Science, Software Engineering, Information Technology, or a related quantitative field (or equivalent practical experience).
• Relevant technical certifications (Java/Spring, Kubernetes, Cloud Practitioner) are a plus.
