In this role, you will set the technical direction for backend architecture, lead hands-on development of critical services, and shape the engineering standards that ensure the platform remains scalable, secure, and resilient at enterprise scale. You will work at the intersection of architecture, delivery, and technical leadership - influencing decisions that have direct impact on how Citi's clients and internal users connect with its digital ecosystem.

Responsibilities

  • Implement security-first engineering practices across all backend components, including single sign-on, centralized access control, and alignment with cyber defense standards.
  • Optimize platform performance through caching strategies, asynchronous processing, and efficient data access patterns to meet the demands of millions of daily transactions.
  • Architect integration solutions that connect a broad range of content provider applications into the unified platform through secure HTTPS-based interfaces.
  • Lead technical decision-making in collaboration with product management, front-end engineers, architects, and infrastructure teams to deliver features end-to-end.
  • Mentor senior engineers through structured code reviews and hands-on guidance, raising engineering standards across design patterns, testing, and operational practices.
  • Serve as the technical escalation point for complex production incidents, leading root cause analysis and driving resolution for critical backend services.


Required Qualifications & Skills
  • 6 to 10 years of backend software development experience, with demonstrated expertise architecting and delivering large-scale enterprise platforms.
  • Expert-level proficiency in Java and its associated frameworks, applied to building high-performance, fault-tolerant services in production environments.
  • Deep working knowledge of distributed systems, microservices architectures, and RESTful API design at scale.
  • Hands-on experience implementing identity and access management solutions, including OAuth2 and OpenID Connect protocols and fine-grained authorization models.
  • Solid experience with cloud-native development using Docker and Kubernetes, and hands-on exposure to GCP and AWS environments.
  • Working knowledge of both relational and NoSQL database technologies, with the ability to select and apply the right solution to complex data challenges.
  • A bachelor's degree or equivalent practical experience, with a master's degree preferred.


Beneficial Skills & Qualifications
  • Familiarity with additional backend technologies including Unix environments, Oracle databases, and distributed caching solutions.
  • Experience integrating AI capabilities into backend services or workflows.
  • Working knowledge of frontend integration considerations including ReactJS, Content Security Policy, corporate design systems, and accessibility standards.

At Citi, you will work on technology that operates at a scale few engineering roles can match - shaping the backend systems that millions of users depend on every day. This is a role for an engineer who wants genuine technical ownership, strategic influence, and the opportunity to grow within one of the world's leading financial institutions.
  • Hybrid working model with 3 days in the office and 2 days working remotely, giving you the structure of in-person collaboration alongside genuine flexibility.
  • Strategic technical ownership of backend systems with a global footprint, with the autonomy to drive architectural decisions that matter at enterprise scale.
  • Access to continuous learning and development resources to deepen your technical expertise and grow your career at Citi.
