To be successful, you will demonstrate:

 * A strong background in hands-on Java engineering, currently working with Java 11+
 * Indepth knowledge of microservices architecture and usage of Spring/Spring Boot
 * Experience developing distributed, real-time applications with deep knowledge of Reactive Programming Principles and tools like Akka, Kafka, WebFlux, RXJava
 * Hands-on experience of both MongoDB and AWS cloud
 * Industry experience within Financial Services, preferably within the Payments arena or at the very least, high volume, low latency platforms
