Revolutionize Business in our Digital Team

Transform how employees and customers connect

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.  Your work will directly impact the business because our agents depend on their Firewall Network connectivity.  You’ll be responsible for firewall policy management and making sure we have our web servers talking to our application servers and the application servers talking to the database. 

You will showcase your technical and non-technical abilities that contribute to the design, implementation, support and refinement of firewall and security infrastructures.  We are about results and as a Sr. Security Firewall Engineer, you’ll be expected to deliver on Execution, Customer Focus, Quality of Work, Teamwork and Decision Making. 

Your goal will be to ensure firewalls meet standards, review vulnerabilities and alerts and update code.  There may also be some interaction with our vendors to solve problems.  You will also be working with other IT departments handling multiple projects at any time.  You’ll review project design and how it fits in the network, providing the design teams and Project Managers feedback on what the design should look like.  You’ll determine if we are meeting the security and compliance standard and you’ll provide feedback to the manager for final approval.  This is a high-touch customer service role where you need to help guide our partners to the correct result.

The first 6 months, it will be very fast-paced; you will be exposed to the technology we use every day in our business, and you will also be introduced to our on-call rotation schedule. 

Our biggest challenges come with the sheer volume of work.  We take a variety of firewall requests every day from our ticketing tools and we will write the firewall rules for those requests.  You’ll have responsibilities of day-time work and some implementations during off hours and during a maintenance window. 

Here at ATT’s Technology Security Operation, you’ll have the opportunities to grow your career.  You are exposed to much technology and may also develop relationships with key folks in other areas.  If you have the drive and energy to learn, we want to help you meet your career goals.
