Senior Full Stack Developer - Oracle Ledger Program

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.

Reasons to use Rodeo

I’m in my final year doing Economics and I don’t know whether to apply for grad schemes now or do a masters first. What do you think?

Honest answer — it depends on where you want to end up. A lot of top grad schemes (Big 4, civil service, banking) don’t need a masters. Let’s look at the ones you’d be competitive for now, and we can decide if a masters actually adds anything.

Also worth knowing: most autumn 2026 applications are open now. Timing matters more than you think.

Start with a chat, not a search bar

Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
