Job Description

We are GDIT. The people supporting and securing some of the most complex government, defense, and intelligence projects across the country.

The IRS Cyber Threat Fusion Center (CTFC) owns the enterprise network firewall policy.  The configuration of the firewalls themselves and execution of approved firewall policy changes are handled by the User and Network Services (UNS) team, but the approval and management of all firewall change requests is the responsibility of the CTFC.  Having the singular goal of protecting taxpayer information, the CTFC and UNS teams work closely to ensure that all firewall changes are authorized, appropriate, and implemented in a manner consistent with least privilege principles.

GDIT is seeking an individual to support the staff currently managing the firewall change request process.  This process includes:

  • Understanding the technical network details of the firewall change request
  • Understanding the request in the context of broader IRS IT modernization initiatives
  • Working with the UNS team to identify any gaps in the request that may require interaction with the customer
  • Ensuring the request has been authorized
  • Approving authorized requests in a timely manner
  • Validating that approved firewall change requests have been implemented in a manner consistent with least privilege; includes review of firewall log events to validate proper implementation
  • Closing completed firewall change requests that have been successfully implemented by associating the individual firewall policy changes with the original request; this maintains the required audit trail

The initial responsibility of the individual will be closing the back log of completed firewall change requests.  This will alleviate a critical choke point in the current process and enable the individual to develop a firm understanding of the overall firewall change request process, the enterprise network architecture, the key functions within the larger IT organization and develop relationships with subject matter experts.  Once the backlog has been addressed, the individual is expected to have a more proactive role in the earlier stages of the firewall change request process.

Required Skills:

  • Solid networking background including operational understanding of IP networking fundamentals such as IPv4 and IPv6 network addressing, subnetting, routing principles, TCP and UDP, RFC1918 IP addressing, encrypted vs unencrypted protocols, application of security at various layers of the OSI model
  • Clear understanding of how firewall policy works, and the difference between port based and application layer (next generation) firewalls
  • Ability to clearly communicate both written and verbal, including technical documentation
  • Ability to analyze and interpret network [e.g., firewall] log events
  • Ability to prioritize tasks
  • 8+ years of experience

Desired Skills:

  • Experience as a firewall administrator
  • Experience with Palo Alto and FortiGate firewalls
  • Experience with Splunk for log review / traffic analysis


  • Full-flex work week
  • 401K with company match
  • Customizable health benefits packages
  • Collaborative teams of highly motivated critical thinkers and innovators
  • Internal mobility team dedicated to helping you own your career
  • Rewards program for high-performing employees
