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
- Define and evolve the backend architecture for an enterprise‑scale digital platform, ensuring systems are built for scalability, reliability, and long‑term maintainability.
- Design and build high-performance backend services and APIs in Java, covering core capabilities including user authentication, authorization, content routing, and data integration.
- 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.
