What you'll do

 * Design and develop scalable, resilient, message-driven services using Java
 * Write clean and future proof code with 80% unit test test coverage, end to end and integration testing before deploying into event driven microservices architecture
 * Optimise payment modules/services to ensure reliability, maintainability, performance and scalability
 * Drive innovation by researching and adopting the latest trends and technologies in backend development, ensuring our applications remain cutting-edge
 * Be a technical mentor for junior developers, providing guidance and support to help them grow and excel in their careers
