• Responsible for implementing data access and persistence using MongoDB and SQL/PLSQL, while ensuring production readiness through centralized logging/observability (ELK) and strong troubleshooting practices.
• Implement event-driven integrations using Kafka (topics, producers/consumers) to enable reliable asynchronous processing across services.
• Build and maintain full-stack features (UI + API layers) and integrate with downstream services/APIs as required.
• Apply multithreading/concurrency concepts where needed for performance, throughput, and responsiveness in backend processing (e.g., scheduled jobs / high-volume flows).
• Design and optimize persistence/data access using MongoDB and RDBMS (SQL/PLSQL), including query optimization and schema-level considerations.
• Enable strong observability and troubleshooting by leveraging centralized logging/monitoring practices and tools such as ELK and related platforms.
• Support CI/CD and deployment readiness by working with containerized/microservices ecosystems (e.g., Docker/OpenShift patterns used in similar Citi programs).
• Participate in production support and engineering excellence—analyzing alerts, performing root-cause analysis, and implementing fixes to maintain stability.
• Work experience on the transactional applications for low latency, high availability uses is a plus
• Work experience on the distributed caching solutions is a plus
• Ability to work in a fast-paced and agile development environment and to learn new frameworks/stacks

• Conduct thorough code reviews, ensuring adherence to best practices in readability, performance, and security.
• Implement and enforce secure coding practices, performing vulnerability assessments and ensuring compliance with security standards.
• Collaborate effectively in agile environments, embracing DevOps principles and fostering a culture of continuous delivery and improvement

Technical Leadership & Collaboration

• Partner with architects, product owners, and cross-functional teams to design scalable and distributed systems.
• Mentor junior engineers and foster a culture of engineering excellence and continuous learning.
• Collaborate closely with DevOps teams to optimize deployments, observability, and production resilience.
