Original job description

Citi is looking for a Senior Java Developer to design, build, and evolve enterprise-grade shared services that underpin high-volume, mission-critical financial systems. In this role, you will lead technical delivery across the full development lifecycle, shaping architecture decisions and setting engineering standards within a globally connected technology team. This is an opportunity to take real ownership of complex backend platforms and directly influence how Citi's technology ecosystem performs at scale.

Responsibilities

Design and develop enterprise shared services using Java, Spring Boot, and MongoDB, ensuring solutions meet performance, reliability, and scalability requirements in high-transactional environments.
Lead integration across messaging and middleware platforms - including WebSphere MQ, TIBCO EMS, Apache Camel, and JMS - to deliver seamless, resilient system connectivity.
Define and enforce engineering standards for coding, testing, debugging, and deployment, driving consistency and quality across the development team.
Collaborate with architecture and infrastructure teams to ensure application designs align with the broader technology blueprint and long-term platform strategy.
Provide Tier 3 production support, diagnosing and resolving high-impact incidents through structured analysis and advanced troubleshooting techniques.
Mentor and guide mid-level developers and analysts, allocating work effectively and building technical capability across the team.
Partner with engineering and product stakeholders to identify system enhancement opportunities and translate business requirements into practical, high-quality technical solutions.

Required Qualifications & Skills

6+ years of hands-on experience developing and maintaining enterprise shared services using Java, Spring Boot, and MongoDB.
Deep expertise in Java 8, Apache Camel, JMS, WebSphere MQ, TIBCO EMS, OSGi, REST APIs, SSL, and related open-source technologies.
Demonstrated ability to perform critical-situation troubleshooting across complex, high-traffic backend environments.
Practical knowledge of DevOps tooling, including GitHub, uDeploy, and SonarQube, with experience integrating these into an Agile development lifecycle.
Working knowledge of SQL and the ability to apply it effectively in application analysis, tuning, and performance measurement.
Proven ability to lead technical delivery, manage competing priorities, and operate with professional maturity across all levels of an organization.
Bachelor's degree in a relevant field, or equivalent practical experience.

Beneficial Skills & Qualifications

Experience with containerization technologies such as Docker and OpenShift.
Familiarity with critical-incident diagnostic tools including Samurai, Thread Dump Analyser (TDA), or Memory Analyser Tool (MAT).
Hands-on experience with Linux command-line administration, particularly in Red Hat Enterprise Linux (RHEL) environments.
Experience with the Lightspeed deployment platform within a regulated or enterprise financial services context.
Master's degree in Computer Science, Engineering, or a related discipline.

What We Offer

At Citi, you will work alongside experienced engineers on technology that operates at global scale, giving you the platform to solve genuinely complex problems and make a tangible impact on systems used by clients and institutions worldwide. We invest in our people through structured development, meaningful work, and a balanced working model designed to support long-term performance and wellbeing.

A hybrid working model with 3 days in the office and 2 days working remotely, providing flexibility alongside team collaboration.
Ownership of technically complex, high-impact engineering challenges in a global financial services environment.
Access to learning and development programmes that support continued technical growth and career progression at a senior level.
A performance-driven team culture that values engineering excellence, accountability, and cross-functional collaboration.
Competitive financial wellbeing support, including compensation and benefits structured to reflect the seniority and scope of this role.
Wellbeing resources and family support benefits designed to help you maintain balance across professional and personal priorities.

Apply now to bring your Java engineering expertise to a global platform where your technical leadership will shape the future of enterprise financial technology at Citi.
