Ready to become a Wriker?

As a Senior Cloud Ops engineer at Wrike, you will have advanced skills in designing and managing reliable infrastructure solutions underlying SAAS platform, as well as supporting cloud and data center infrastructure with security in mind - you know how to work with networking, monitoring, automation, and debugging a (reasonably) complex infrastructure. In this role, you'll need to manage your own tasks and oversee others' work within your scope, and lead projects of different sizes.
