Java Developer

We are seeking a skilled and motivated Java Developer to join our team as a developing professional. In this role, you will be a key contributor to the design, development, and maintenance of high-performance, scalable, and resilient microservices. The ideal candidate deals with most problems independently, has some latitude to solve complex problems, and integrates in-depth specialty area knowledge with a solid understanding of industry standards and practices. A passion for innovation, continuous improvement, and strong analytical thinking are essential.

Accountable for the design, development, construction, testing, and implementation of robust, scalable, and secure microservices using Java 17+ and related technologies (e.g., Spring Boot, Spring Cloud, Kafka, Kubernetes). Turn tech stack and application design into code, writing secure, stable, testable, and maintainable code. Participate in the technical design of new features and enhancements, ensuring alignment with the overall system architecture and best practices. Collaborate with product owners, architects, and other developers to translate business requirements into technical solutions, operating with autonomy where some oversight and direction may be required. Address a variety of problems, questions, or situations by applying established criteria to directly influence development outcomes. Take the time to fully learn the functionality, architecture, dependencies, and runtime properties of the systems involved with your projects. Participate in code reviews to ensure code quality, performance, and security, and help improve processes that accelerate delivery, drive innovation, and lower costs. Help identify and resolve technical issues, contributing to root cause analysis. Ensure you and your peers are actively seeking ways to objectively measure productivity (e.g., SonarQube) and automate code quality, unit testing, and build processing in the CI/CD pipeline. Communicate technical concepts clearly and concisely to team members and other technology groups. Appropriately assess risk when business decisions are made, demonstrating particular consideration for the firm's reputation and safeguarding Citigroup, its clients, and assets by driving compliance with applicable laws, rules, and regulations.
