FX Risk Lead Java Developer + AI (VP)

Engineer the future of global finance. At Citi, our Tech team doesn't just support finance - we are helping to redefine it. Every day, $5 trillion crosses through our network.

Look to join a team where your work helps influence economies, your ideas can drive innovation and outcomes, and your growth is backed by mentorship, continuous learning and flexibility with potential hybrid work opportunities. Help solve real-world challenges that touch millions and get the opportunity to build the future of finance with Citi Tech.

What We do / The Team

This isn't just another Java developer role. As a Lead Java Developer - Vice President within Citi's FX Risk technology team, you'll be at the intersection of high-stakes financial engineering and the next generation of AI-powered software development.

At Citi, we are actively redefining how technology drives global finance - every day, $5 trillion crosses our network. You'll architect and deliver the systems that power real-time FX risk management for one of the world's largest financial institutions, working in an environment where AI is not a future ambition - it's how we work today.

You'll have hands-on access to Citi's internal GenAI ecosystem: from GitHub Copilot and Devin.AI for agentic code generation, to Citi Squad for automated code reviews, to Stylus Workspaces - Citi's in-house GenAI platform powered by top-tier LLMs including Gemini, OpenAI, Claude, Llama, and local models. You'll use Prompt Engineering, Workflow Design, and GenAI Optimisation techniques as part of your everyday engineering practice.

This is the next generation of Lead Java Development - where your engineering instincts are amplified by AI, your decisions shape a strategically critical platform, and your impact is felt across global markets.

Role Overview / What will you do:

Lead end-to-end delivery of complex, high-performance Java applications supporting FX risk management across global markets

Architect scalable, low-latency solutions that process real-time risk data at scale - designing for resilience, performance, and security from day one

Drive technical direction and key decisions - from system design and architectural choices to setting engineering standards across the team

Translate complex business requirements into robust, high-quality code - working closely with quantitative analysts, traders, and business stakeholders

Craft high-quality, scalable software in an agile environment, leveraging AI-powered coding tools to accelerate delivery without compromising standards

Share expertise and raise the bar - act as a technical reference point for the team, influencing engineering quality through example, guidance, and knowledge sharing (this is an individual contributor role with no direct reports)

Champion innovation - actively evaluate, propose, and adopt new technologies and frameworks; this team has the mandate and appetite to bring in better tools

Own quality - participate in mandatory cross-team code reviews, supported by Citi Squad AI reviewers and peer engineers, ensuring adherence to security, quality, and compliance standards

Operate in production - take ownership of L3 production support issues, provide timely resolutions, and deliver long-term remediation fixes that address root causes - not just symptoms

Support testing cycles and post-production deployment - from writing TDD-first code to validating releases in a weekly cadence

Contribute to Citi's technology strategy, influencing how the firm approaches risk technology at a global scale
