Open Credo


OpenCredo (OC) is a UK based software development consultancy helping clients achieve more by leveraging modern technology and delivery approaches. We are a bunch of passionate technologists who thrive tackling complex challenges, delivering pragmatic and sustainable solutions for our clients. Curious, tenacious but always sensitive to our clients' context, we are not afraid to speak our minds to help steer our clients towards understanding and achieving their key goals.

A role for a hands-on Lead Java Engineer has opened up with one of our clients. The client is an international payments platform provider. The project is to be part of the team helping to turn their real-time payments platform into a configurable, pluggable product. This is a truly once-in-a-career opportunity to work on a country’s payment system which is classed as “critical national infrastructure”. The project is in its first few phases of development, so is pre-production, with a great deal of performance and resilience features yet-to-be-written. However it is being delivered using a Scrum-based approach to ensure internal milestones are still being met.

The platform itself is a configurable Java 8 platform employing Spring Boot, Spring Data, Apache Camel, Rabbit MQ (although they are shortly upgrading to Java 17). The modern-standard Java development tools and environment are all in heavy use here : Jenkins, Docker, Maven, Cucumber, TestContainers.
