Understanding how to support Mesos/Marathon is not required. However, this candidate needs to have an understanding of Docker Orchestration tools like ECS or Docker Compose. Above all else, the person must be a good team player with an eagerness to learn as well as teach when required. You will work primarily as a software engineer as the infrastructure as code solutions that we utilize require both a Software Engineering and Systems Administrator skillset.
