Full Stack Engineer

Citi is hiring a Head of Application Development at the Senior Vice President level to lead enterprise-scale CRM and financial platform engineering within the Institutional Services Group (ISG), a key division of Citi's Institutional Clients Group (ICG). In this role, you will architect and drive the delivery of mission-critical, high-availability systems that serve global institutional clients — combining deep technical leadership with hands-on engineering excellence. This is an opportunity to shape the technology direction of a platform that disrupts industry norms through innovation and cross-functional collaboration.

Responsibilities

• Lead the architecture and development of enterprise-grade CRM and financial applications, ensuring 24/5 availability and alignment to business objectives across global institutional clients.

• Design and deliver loosely coupled, microservices-based solutions using Java, Spring Boot, and RESTful architecture — driving the migration of monolithic platforms to cloud-ready, scalable architectures.

• Own the engineering roadmap for application stability, quality, and functionality, setting and meeting service level expectations across production environments.

• Automate the release pipeline to achieve zero-downtime deployments across the full application platform, reducing operational risk and accelerating delivery cycles.

• Act as the primary technical liaison between business users, internal technology teams, and external vendors — translating complex requirements into clear, actionable engineering solutions.

• Mentor and coach a cross-functional engineering team of 20 or more, fostering technical growth, knowledge sharing, and high-performance delivery culture.

• Assess technology and business risks during decision-making, ensuring solutions adhere to applicable policies, regulatory standards, and safeguard client assets and firm integrity.

Required Qualifications & Skills

• 10+ years of experience developing and managing enterprise CRM applications, with at least 10 years focused on solution architecture for high-availability financial systems.

• Proven experience leading and managing engineering teams of 20 or more professionals across varied technical disciplines.

• Expert-level proficiency in Java (version 10 or above) and the broader Spring ecosystem, including Spring Boot, Spring Data, JPA, Maven/Gradle, WebSockets, and Test-Driven Development (TDD).

• Hands-on experience designing and developing solutions using Message-Oriented Middleware technologies such as Kafka, TIBCO, and Apache MQ over SSL.

• Deep knowledge of microservices architecture patterns, Object-Oriented Design, and Gang of Four (GoF) design patterns — with demonstrated experience migrating monolithic applications to microservices in on-premises or cloud environments.

• Working knowledge of web service standards including REST, SOAP, JSON, JAXB, and JAX-WS, as well as message formats such as XML, JSON, and Protobuf.

• Bachelor's degree or equivalent practical experience in a relevant engineering or technology discipline.

Beneficial Skills & Qualifications

• Experience architecting enterprise-wide solutions that span multiple business domains, with the ability to communicate complex technical decisions to non-technical stakeholders.

• Demonstrated ability to re-prioritize rapidly in dynamic environments, balancing long-term architecture goals with immediate delivery demands.

• A track record of fostering technical learning and knowledge-sharing practices within large engineering teams.
