Enso Recruitment is working with one of NI's most established blockchain centre's of excellence to recruit for a Senior Technical QA Engineer. If you are a software engineer with a passion for software testing and are interested in working in the Blockchain space, this role could be perfect for you!

This is a great opportunity to work as a Senior Technical QA Engineer on a modern, cloud, blockchain-based platform delivering solutions for a global leader in internet services with more than 1.2 billion members around the world.

The  team in Belfast builds secure, high availability enterprise platforms that allow the many Rakuten Business/Developers to create solutions that take advantage of the benefits of distributed ledger or blockchain technologies without having to be concerned about the complexities of implementation. Their platforms follow a microservice architecture where services are developed in Node.js and deployed as docker containers into a cloud-based Kubernetes environment. There are integrations with relational databases, 3rd party APIs as well as specialised cryptographic services, and of course blockchain networks.

The overall test approach requires a balanced strategy of unit, integration, and end-to-end tests in addition to the non-functional testing such as performance, failure/failover, and security that you would expect for this type of platform.
