Working at Citi is far more than just a job. A career with us means joining a team of more than 230,000 dedicated people from around the globe. At Citi, you’ll have the opportunity to grow your career, give back to your community and make a real impact.

Job Overview

Citi is looking for a Senior Full Stack Developer to join the Oracle Ledger Program, where you will build and maintain the common services and user interfaces that underpin critical financial systems across the organization. In this role, you will work with a high-performing technology team to develop full stack applications, drive technical solutions end-to-end, and provide expert-level support across a global delivery model. This is an opportunity to apply your engineering expertise to systems that directly support Citi's financial infrastructure at scale.

Responsibilities

Design, develop, and maintain full stack applications for the Oracle Ledger Program, building both frontend interfaces and backend services to meet evolving business requirements.
Build and enhance common services and user interfaces using Java, Angular or React, and REST APIs, ensuring high-quality, scalable, and maintainable code.
Lead the full development lifecycle across analysis, design, construction, testing, and implementation to deliver reliable software on schedule.
Provide L3 technical support as part of an around-the-sun global support model, diagnosing and resolving complex application issues with minimal disruption.
Collaborate with business users and cross-functional technology teams to translate requirements into practical technical solutions and recommend the most effective engineering approaches.
Develop and implement automated test coverage using Selenium to validate functionality and protect system integrity across releases.
Define and uphold engineering standards and best practices, contributing to a consistent and maintainable codebase across the team.
Act as a subject matter expert for senior stakeholders and teammates, providing technical guidance and mentoring less experienced developers.

Required Qualifications & Skills

Experience in software development, with a strong focus on full stack engineering across enterprise applications.
Proficiency in Java for backend development, with demonstrated experience building and consuming REST APIs in production environments.
Hands-on experience with Angular or React for building responsive, user-facing web interfaces.
Practical experience with Selenium for automated testing, including writing and maintaining test suites that support continuous delivery.
Proven ability to manage and deliver software projects end-to-end, including planning, prioritization, and delivery under deadline pressure.
Experience providing advanced application support, including root cause analysis and resolution of complex production issues.
Bachelor's degree in a relevant field or equivalent professional experience.

Beneficial Skills & Qualifications

Familiarity with Python for scripting, automation, or data processing tasks within an enterprise application context.
Exposure to Oracle financial systems or ledger-based platforms, providing useful context for the business domain.
Experience working within global or follow-the-sun support and delivery models across distributed teams.
