Monitor and control all phases of development process and analysis, design, construction, testing, and implementation as well as provide user and operational support on applications to business users
Utilize in-depth specialty knowledge of applications development to analyze complex problems/issues, provide evaluation of business process, system process, and industry standards, and make evaluative judgement
Recommend and develop security measures in post implementation analysis of business usage to ensure successful system design and functionality
Consult with users/clients and other technology groups on issues, recommend advanced programming solutions, and install and assist customer exposure systems
Ensure essential procedures are followed and help define operating standards and processes
Serve as advisor or coach to new or lower level analysts
Has the ability to operate with a limited level of direct supervision.
Can exercise independence of judgement and autonomy.
Acts as SME to senior stakeholders and /or other team members.
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, adhering to Policy, applying sound ethical judgment regarding personal behavior, conduct and business practices, and escalating, managing and reporting control issues with transparency.

Skills & Requirements

Strong in Core Java - collections, generics, streams, lambdas, exception handling, OOPs concepts, and multithreading/concurrency (executors, threads).
Strong in Spring Boot - Spring Data, Spring Batch, Spring Security.
Experience with Spring Data JPA/JDBC - repositories, entity mapping, transactions (@Transactional), connection pooling (HikariCP), and lazy/eager loading.
Hands-on with Spring Security - authentication/authorization, BCrypt, role-based access control, and securing REST endpoints.
Design, develop, and maintain RESTful APIs using Java and Spring Boot.
Good understanding of the end-to-end API development lifecycle - from design and contract definition through implementation, testing, deployment, and monitoring.
Strong understanding and implementation experience of integrating APIs with API gateways such as Apigee and Amazon API Gateway.
Proficient with Jackson (ObjectMapper config, custom serializers, strict request validation) and OpenAPI/Swagger for API documentation.
Write and optimize complex Oracle SQL queries (multi-table joins, analytic functions, subqueries, performance tuning).
Experience with Kafka, MQ, or event-streaming platforms for real-time data ingestion and processing.
Open to working on data pipelines and building ETL workflows using Java or other programming languages such as Scala as required.
Work with data warehousing concepts - fact/dimension modeling, slowly changing dimensions, and data quality checks.
Basic understanding of the Big Data ecosystem is a plus.
Good to have experience building and optimizing data workflows using tools such as Apache Spark.

Recommended Qualifications:

4+ years of relevant experience
Experience in systems analysis and programming of software applications
Experience in managing and implementing successful projects
Working knowledge of consulting/project management techniques/methods
