Role Overview
We are seeking detail-oriented senior/lead engineers to join our Release Management (RM) team, focusing on infrastructure, specifically compute and hypervisor. This team is responsible for the RM of bare metal servers and VMware VSphere hypervisors supporting a large Avaya UC and CC solution. In addition to software/firmware updates of servers and VMware, the RM team is responsible for ensuring the RM process is non-disruptive to the client's solution. A least disruptive process is achieved through validation/testing of all releases, optimizing and testing the process of applying the releases, and pre- and post-implementation health checks to ensure a fully functioning solution.
The senior/lead roles will take additional responsibility: analyzing the test results, outcomes, processes and workflows of the RM team and recommend/develop continuous improvements; utilize scripts and other tools to automate RM team processes.
The lead role will take additional responsibility: technical team leadership.
All roles will given opportunity with training to expand their skills/experience in performing release management tasks on additional infrastructure components, including top-of-rack network switches and SAN/NAS storage solutions in the environment.
