Job Overview

Job Description

We are seeking a highly skilled and experienced Java Developer to join our Equities Electronic Trading team. This is a VP-level position responsible for the design, development, and optimization of the tools and automation that underpin our core low-latency execution platform. The overall objective of this role is to drive the technical implementation and innovation of operational, stability, and development tooling for electronic trading — including next-generation AI tooling and agents — utilizing modern, high-performance Java and a microservices-based architecture.

Responsibilities:

• Take a leading role in the design, development, and optimization of high-performance tools, automation services, and applications that support the operation, stability, and delivery of our electronic trading platform.
• Implement and enhance operational automation, including runbooks, support workflows, trade reconciliation, exception handling, and environment/configuration management, to improve the stability, scalability, and efficiency of our execution systems.
• Design and build stability tooling for monitoring, observability, alerting, failover, and application recovery to reduce time-to-detect and time-to-recover in a low-latency, high-throughput environment.
• Build and apply AI tooling and agents to create a next-generation toolkit for Electronic Equities — automating diagnosis, runbook execution, code and test generation, developer inner-loop tasks, and operational decision support, with appropriate human-in-the-loop controls.
• Drive continuous improvement initiatives in testing frameworks, development tools, CI/CD, and deployment processes to raise developer productivity and delivery quality for Electronic Equities.
• Participate in and lead technical design discussions and conduct rigorous code reviews to ensure the highest standards of quality, performance, and architectural integrity across tools and automation.
• Partner with product development, quantitative researchers, production support, and other technology teams to deliver new trading capabilities and to automate how existing systems are built, tested, released, and operated.
• Resolve complex technical challenges through in-depth analysis of business requirements, operational processes, system behavior, and industry best practices.
• Apply expert knowledge of system architecture, data flow, and development standards for coding, testing, debugging, and implementation of tools and automation.
• Build and maintain robust solutions for trading platform monitoring, trade reconciliation, and application recovery.
• Appropriately assess risk when business decisions are made, demonstrating particular consideration for the firm's reputation and safeguarding Citigroup, its clients and assets, by driving compliance with applicable laws, rules and regulations, adhering to Policy, applying sound ethical judgment regarding personal behavior, conduct and business practices, and escalating, managing and reporting control issues with transparency.

Qualifications:

• 5+ years of hands-on experience in software development with a strong focus on high-performance, low-latency systems and on tools, automation, or internal platforms that support them.
• Expert-level technical knowledge in Core Java, including a deep understanding of JVM internals, concurrency, garbage collection, and memory management in a low-latency context.
• Proven experience designing and developing tools, automation, and operational platforms for automated trading systems or electronic execution platforms in Equities or other similar financial domains.
• Experience building and using AI tooling and agents (e.g., LLM-based assistants, agentic workflows, tool-calling services) to automate operational, stability, and development tasks, with a practical understanding of controls, evaluation, and production-safe usage.
• Solid understanding of financial market protocols (e.g., FIX) and practical experience handling order and market datasets.
• Experience with microservices architecture and developing distributed systems.
• Demonstrable experience with modern testing frameworks, Agile methodologies, and Continuous Integration/Continuous Delivery (CI/CD) processes, including building or evolving developer and deployment tooling.
• Excellent communication skills with a demonstrable ability to present and grasp complex technical and business concepts.
• Familiarity with messaging and data grid technologies (e.g., Solace, AMPS, Chronicle) and infrastructure automation tools (e.g., Ansible) is a plus.
• Bachelor's degree/University degree or equivalent experience; Master's degree preferred.
