· You have experience with implementing cloud-native applications using open and closed source standards and solutions such as Open Policy Agent (OPA), Docker, Kubernetes, RedHat OpenShift, Cloud Foundry, and public cloud providers such as AWS, Azure and GCP

· You have a good working knowledge of microservices architectures, Rest APIs, streaming and message queueing systems (Kafka etc.) and how to instrument them

· You are familiar with DevSecOps disciplines and have an understanding of CI/CD using modern tools such as TeamCity, Jenkins, Tekton, Spinnaker etc.

· You love working together on scalable systems, embracing new technologies, and pushing the boundaries of “the art of the possible”
