Reporting to an Associate Director of Technology Security Operation (TSO), you will work with high level of proficiency and expertise within the Firewall Security framework. You will provide connectivity for users or applications as well as working with our application teams to roll out new applications.

This is a high-touch customer service role where you need to help guide our partners to the correct result.
