• Microservices Development: Develop reusable software components within a cloud-native, microservices-based architecture to support core clearing functions, margin payments, and position limits management.
• Hands-on Coding: Write clean, high-quality, and secure code utilizing Java and modern frameworks. Develop high-performing front-end screens (Angular) utilizing in-house libraries with an emphasis on design patterns and reusability.
• Position Limits & Clearing Logic: Design and implement business logic to handle complex position limits (including exchange-mandated, regulatory, and house limits) and straight-through processing of futures clearing flows.
• DevOps & CI/CD: Implement and maintain automated build, test, and deployment pipelines utilizing Citi’s modern DevOps toolchain (Bitbucket, Jenkins, OpenShift).
• Quality & Test Automation: Partner closely with QA engineers to drive test automation efforts early in the software development lifecycle (SDLC).
• Collaboration & Mentorship: Collaborate with cross-functional teams to build shared libraries. Mentor and coach junior team members, enforcing governance around development and testing standards.

Required Technical Skills

• Java Expertise: Highly skilled and hands-on with Java (Core Java, Multithreading, Concurrency) and the Spring Ecosystem (Spring Boot, Spring Cloud, Spring Security).
• Microservices Architecture: Strong, demonstrated experience in designing, developing, and deploying distributed, event-driven microservice-based architectures.
• Containerization & Orchestration: Highly skilled in deploying and managing cloud-native applications on Docker and OpenShift/Kubernetes platforms.
• Database & Messaging: Strong proficiency in SQL (relational databases) and enterprise messaging middleware such as Kafka or IBM MQ.
• Front-End Development: Hands-on experience with web technologies including JavaScript, Angular, HTML5, and CSS.
• Agile Methodologies: Proven experience working in an Agile/Scrum environment within a global, matrixed organization.

Required Functional & Domain Knowledge

• Futures Clearing: Decent functional understanding of the exchange-traded derivatives (ETD) trade lifecycle, clearing workflows, trade allocations, and integrations with global clearinghouses.
• Position Limits: Good working knowledge of position limits management, including real-time monitoring, regulatory reporting requirements, and limit breach mitigation workflows.

Desirable Skills & Competencies

• Application Security: Experience implementing security protocols and standards (OAuth, TLS/SSL, SSH, SFTP, and PKI).
• Caching Technologies: Experience with distributed caching solutions (e.g., Gemfire, Redis) to optimize low-latency processing.

Professional Attributes

Detail-oriented, self-organized, and proactive with exceptional written and verbal communication skills. Ability to manage tight deadlines and navigate ambiguity in a high-pressure global environment.
