The role also includes production support, technical documentation, code reviews, testing, and continuous improvement.

Key Responsibilities

• Design and develop backend microservices using Spring Boot and Spring Framework for retail banking applications.
• Build Python-based services, utilities, automation scripts, and data-processing components that improve workflow efficiency and system reliability.
• Develop and optimize SQL queries, stored procedures, indexing strategies, and data-access components for high-volume transaction processing.
• Connect microservices with relational databases and internal banking platforms while maintaining data consistency and auditability.
• Translate retail banking requirements into practical technical designs and implementation plans in collaboration with product owners and architects.
• Apply secure development practices covering authentication, authorization, data protection, input validation, encryption, and access control.
• Create and maintain unit, integration, and regression tests to support dependable software releases.
• Investigate application and database performance issues and apply appropriate tuning techniques to improve stability and response times.
• Participate in technical discussions and code reviews to promote maintainable code, reusable components, and consistent engineering patterns.
• Maintain technical documentation covering APIs, data models, service interactions, and operational details.
• Work with reliability and operations teams on deployment processes, configuration management, monitoring, and production workloads.
• Troubleshoot production incidents, perform root cause analysis, and implement lasting corrective solutions.
• Contribute ideas that improve development tools, engineering practices, system architecture, and the long-term retail banking platform.

Required Skills

The ideal candidate should have strong backend development experience with Spring Boot and Spring Framework in enterprise environments. Advanced Python skills are required for developing services, automation utilities, and data-processing solutions.
