Senior Java Backend Engineer

Working at Citi is far more than just a job. A career with us means joining a team of approximately 219,000 dedicated people from around the globe. At Citi, you’ll have the opportunity to grow your career, give back to your community and make a real impact.

We are looking for a Senior Java Backend Engineer (C12) in Pune to join the core engineering team building Vendor Master Central (VMC)—an enterprise-scale registry platform responsible for ingesting, reconciling, and managing millions of market data service records, contracts, and vendor hierarchies.

This role is backend-first, centered on designing high-throughput ingestion pipelines, resilient Spring Boot microservices, clean RESTful APIs, and domain data models. Experience or interest in Full Stack development with React/TypeScript is a strong plus, enabling end-to-end feature ownership from backend services up to user-facing web tools.

We actively embrace GenAI-assisted engineering (Devin, GitHub Copilot, Cursor) to automate boilerplate, accelerate unit testing, and achieve high engineering velocity.

• Backend Microservices: Design, build, and maintain production-grade REST APIs and microservices using Java 21/25 and Spring Boot.
• Data Ingestion & Processing: Build resilient ETL and reconciliation services that ingest, validate, and deduplicate complex monthly datasets from multiple upstream sources into a unified data model.
• Data Modeling & Storage: Design relational schemas (PostgreSQL / Oracle), optimize complex SQL queries, and implement transactional data integrity, staging layers, and immutable audit logs.
• Full Stack Collaboration (Bonus): Partner with or contribute to the React/TypeScript frontend to integrate APIs seamlessly with data grids, curation drawers, and bulk Excel upload workflows.
• GenAI Velocity: Leverage AI-powered developer tooling (Devin, Copilot, Cursor) for rapid prototyping, component scaffolding, and automated test coverage.
• Engineering Excellence: Drive high code quality through TDD/BDD (JUnit 5, Mockito), automated CI/CD pipelines, containerization (Docker/OpenShift), and code reviews.
• Mentorship & Ownership: Act as a technical pillar within the Pune agile squad, collaborating with global teams and mentoring junior engineers.

• 5–8+ years of hands-on software development experience with core focus on Java (21/25) and Spring / Spring Boot.
• Strong foundation in RESTful API design, microservice architecture, and enterprise integration patterns.
• Deep expertise in relational databases (SQL), schema design, data indexing, transactions, and performance tuning (PostgreSQL, Oracle, or MySQL).
• Solid experience building data ingestion, transformation, or batch processing pipelines.
• Strong testing discipline: unit testing, integration testing, and mock frameworks (JUnit, Mockito, Testcontainers).
• Experience with modern DevOps pipelines (Git, Maven/Gradle, Jenkins/Tekton, Docker, Linux).

• Experience or familiarity with React, TypeScript, or modern frontend SPAs (state management, component design, data grids).
• Familiarity with client/server Excel file processing (.xlsx generation, bulk upload parsing).
• Experience working with autonomous AI engineering agents (e.g., Devin) or AI-assisted coding tools.
• Experience with message brokers or event streaming (Kafka, MQ).

• Education: Bachelor’s degree in Computer Science, Software Engineering, or equivalent practical experience.
• Autonomy & Judgment: Ability to operate with limited direct supervision, make sound architectural choices, and deliver features independently.
• Communication: Strong English communication skills and ability to collaborate across distributed global teams (India, UK, US).
• Risk & Controls: Sound understanding of secure coding practices, data governance, and enterprise security standards.
