• Test Automation: Write and maintain automated tests at the API, FIX messaging and end-to-end layers using Java or Python and BDD tools such as Cucumber, and promote good standards for test design and code quality.
• Test Planning & Process: Contribute to risk-based test strategies and release test plans, and take part in the test process from requirements review through regression, performance and UAT support to release sign-off. Report quality metrics and support root-cause analysis.
• Test Environment Support: Automate the provisioning, deployment and data refresh of test environments (dev, SIT, UAT, pre-production), using Docker and OpenShift to provide isolated, on-demand environments that reflect production.
• Product Collaboration: Partner with developers, traders and quantitative researchers to understand testing and tooling needs and turn them into improvements.
• Agile & CI/CD: Contribute to and champion Agile practices and CI/CD processes, with continuous testing, automated quality gates and a focus on shift-left testing and faster releases.
• AI-Powered SDLC: Leverage Citi's AI-powered development tools across the SDLC to enhance productivity, code quality and innovation.

Qualifications

• Minimum 7 years of software development experience, with strong proficiency in Java or Python.
• Experience building internal tools, frameworks or platforms, preferably for testing, simulation or environment automation.
• In-depth knowledge of the FIX protocol and experience with FIX-based order flow.
• Strong understanding of automated testing techniques and quality engineering practices, including BDD frameworks (for example Cucumber).
• Experience with Docker, OpenShift and CI/CD pipelines (for example Jenkins or similar).
• Experience in financial services with exposure to trading systems, and familiarity with performance, latency and high-throughput system concepts.
• Solid understanding of Agile methodologies.
• Strong problem-solving and communication skills, with the ability to prioritize multiple tasks in a fast-paced, globally distributed environment.
• Knowledge of algorithmic trading, SOR, and regional exchange microstructure and regulatory regimes is an advantage.
