Senior Java Engineer – Backend & AI-Assistant Vice President

Citi is looking for a Senior Java Engineer to design and deliver high-performance backend systems at the intersection of enterprise software development and applied AI tooling. Based within Citi's Technology organization, this role offers the opportunity to build production-grade Java applications using Spring Boot and MongoDB while actively integrating modern AI-assisted development practices into everyday engineering workflows. You will operate with meaningful autonomy, owning application modules end-to-end and contributing to the standards that shape how the team builds and ships software.

• Design, develop, and deploy robust backend applications using Java and Spring Boot, with MongoDB as the primary data store, ensuring performance, reliability, and maintainability at scale.
• Build and maintain RESTful APIs and microservices that meet defined business requirements, translating complex functional needs into clean, efficient backend solutions.
• Own and deliver discrete application modules from requirements through to production, maintaining accountability across the full software development lifecycle including analysis, design, construction, testing, and release.
• Identify and surface technical and delivery risks early, proposing concrete mitigation plans to keep projects on track.
• Integrate and champion AI-assisted development tools — including GitHub Copilot, Devin, Claude, and Codex — to accelerate delivery and improve code quality across the team.
• Define and uphold engineering standards and operational processes, contributing to a consistent and high-quality development practice.
• Apply sound technical judgement when assessing the impact of decisions on system integrity, data quality, and business outcomes, escalating issues transparently where needed.

• 5+ years of backend software engineering experience, with a focus on Java application development in commercial or enterprise environments.
• Deep expertise across the Spring Framework ecosystem, including Spring Boot, Spring MVC, Spring Data JPA, and Spring Security.
• Demonstrated ability to design and implement RESTful APIs and microservices architectures that are scalable, secure, and well-documented.
• Hands-on experience with CI/CD pipelines and tooling, including Jenkins, GitLab CI, GitHub Actions, Docker, Kubernetes, and Maven or Gradle.
• Solid command of Git version control and established branching strategies such as Gitflow, applied in a team delivery context.
• Practical experience working with AI-assisted development tools such as GitHub Copilot, Devin, Claude, Codex, or equivalent, as part of a professional engineering workflow.
• Familiarity with web service standards including REST and SOAP, and data formats including XML and JSON.

• Frontend development experience using Angular, enabling collaboration with full stack teams and contribution to end-to-end feature delivery is nice to have.
• Experience managing or contributing to software delivery projects, with the ability to coordinate workstreams and meet shifting deadlines effectively.
• Exposure to project management or consulting methodologies that support structured delivery in complex engineering environments.
• A bachelor's degree in Computer Science, Engineering, or a related field — or equivalent practical experience.

At Citi, you will work on technology that operates at genuine global scale, within a team that values engineering craft, clear ownership, and continuous improvement. This is a role where your backend expertise will have direct impact — not just on internal systems, but on how Citi delivers for its clients worldwide.

• A hybrid working arrangement with 3 days in the office and 2 days working remotely, giving you flexibility alongside meaningful in-person collaboration.
• The opportunity to work at the forefront of AI-augmented software engineering, using tools like GitHub Copilot, Devin, and Claude as a standard part of how the team builds.
• Clear scope for technical growth, with exposure to complex, high-stakes backend systems and the autonomy to shape how they evolve.
• Access to learning and development resources that support progression across both technical depth and broader engineering leadership.
• A performance-driven environment where your contributions are visible, your ownership is real, and the problems you solve carry meaningful consequences.
• Competitive compensation and a benefits package designed to support your financial wellbeing, health, and long-term career at one of the world's leading financial institutions.
