• Troubleshoot and resolve issues across servers, environments, and live production services
• Test and debug APIs and services using tools such as Postman
• Contribute to service design, system architecture, and backend engineering best practices
• Work closely with technical stakeholders to ensure secure, scalable, and reliable solutions

Required Skills & Experience

• 6–8 years of hands-on Java development experience
• Strong experience building microservices architectures in Java
• Deep knowledge of Spring Boot, Spring MVC, and Spring Security
• Strong understanding of OAuth2 authentication and authorisation mechanisms
• Experience developing and maintaining REST APIs
