• Lead development of RESTful APIs and microservices along with mobile platforms, ensuring consistency and alignment with business and UX goals.
• Drive integration with API Gateway technologies (e.g., Kong, Apigee, AWS API Gateway) to enforce access control, rate limiting, and API lifecycle management.
• Implement robust authentication and authorization workflows using IDAM platforms such as Ping Identity, Okta, or Auth0, with support for OAuth2, OIDC, and JWT.
• Collaborate with mobile app teams to ensure backend services are optimized for mobile-specific use cases such as performance, caching, and offline access.
• Own end-to-end technical delivery, including code quality, performance optimization, security best practices, and CI/CD integration.
• Perform code and design reviews, define technical standards, and mentor developers across the team.
• Troubleshoot and resolve complex system issues in development and production environments.
• Contribute to solutioning, estimations, and project planning in agile delivery models.

• Bachelor’s or Master’s degree in computer science, Engineering, or related field.
• 10+ years of professional experience in backend development, with at least 3+ years in technical leadership or solution design roles.
• Strong expertise in Java, Spring Boot, and the Spring ecosystem (Spring MVC, Data, Security).
• Proven experience architecting and deploying microservices-based systems in complex enterprise environments.
• Hands-on experience with API Gateways (Kong, Apigee, or AWS API Gateway) and secure API development.
• Working knowledge of IDAM platforms like Ping Identity, Auth0, or Okta.
• Work closely with mobile app teams to ensure backend services are optimized for mobile/web delivery.
• Experience working in banking or financial services domain, with understanding of regulatory and security considerations.
• Proficiency in SQL and RDBMS (PostgreSQL, MySQL, Oracle), and familiarity with CI/CD and DevOps tooling (GitHub Actions, Jenkins, GitLab CI).
• Excellent communication, collaboration, and technical documentation skills.

Preferred Qualifications:

• Exposure to mobile application development lifecycle, backend-for-frontend (BFF) patterns, and mobile performance optimization.
• Experience with NoSQL databases (e.g., MongoDB, Cassandra).
• Familiarity with cloud platforms (AWS, GCP, Azure) and container orchestration (Kubernetes).
• Knowledge of event-driven or reactive architectures, messaging systems (Kafka, RabbitMQ), or domain-driven design (DDD).
• Agile development experience using tools like Jira, Confluence, and participation in SAFe or Scrum environments.
• Contributions to architecture governance, tech evaluations, or engineering playbooks.
