plugin development, optimize build processes, and ensure concurrency handling while maintaining robust security controls. The role requires a deep technical understanding of

secure coding practices, authentication mechanisms, encryption techniques, and security vulnerabilities. You will collaborate with cross-functional teams, including security engineers,

DevOps, and architects, to ensure that our software solutions meet high security and performance standards.

Key Responsibilities:

• Design, develop, and optimize applications using Java 11+ and Kotlin.
• Utilize Java's functional programming features, Streams API, and concurrency utilities.
• Implement coroutines and asynchronous processing in Kotlin for optimized performance.
• Ensure adherence to secure coding principles to prevent security vulnerabilities such asSQL injection, XSS, CSRF, and buffer overflows.
• Configure and optimize Maven and Gradle for dependency management and build automation.
• Ensure secure handling of dependencies and mitigate risks associated with third-party libraries.
• Enhance build performance and implement continuous integration (CI/CD) best practices.
• Design and implement high-performance, thread-safe applications using Java/Kotlin concurrency frameworks.
• Optimize resource management with techniques like thread pooling, non-blocking I/O, and reactive programming.
• Implement secure concurrent programming practices to prevent race conditions, deadlocks, and data integrity issues.
• Develop custom plugins/extensions for Eclipse and IntelliJ IDEA to enhance development workflows.
• Work with IDE SDKs to integrate custom tools, automation scripts, and security enhancements.
• Debug and optimize plugins for performance, security, and seamless integration.
• Utilize creational, structural, and behavioural design patterns for scalable and maintainable software.
• Architect solutions that adhere to SOLID principles and secure software development lifecycle (SSDLC).
• Implement best practices for dependency injection, microservices, and domain-driven design.
• Design and maintain on-premises deployment solutions, ensuring security best practices.
• Secure server configurations, perform penetration testing, and implement role-based access control (RBAC).
• Ensure compliance with security standards such as OWASP Top 10, NIST, and ISO 27001.
• Apply encryption techniques, authentication mechanisms (OAuth, JWT, SAML), and secure API design.
• Work with DevOps teams to harden deployment environments and ensure secure on- premises configurations.

Required Skills & Qualifications:
