  • Support vulnerability remediation, system hardening, access reviews, incident response, audit evidence, and continuous control improvement.
  • Maintain system and network diagrams, standards, procedures, inventories, change records, and recovery documentation.
  • Manage and test backup, disaster recovery, and business continuity capabilities.
  • Collaborate across security, compliance, applications, data, operational technology, and business teams.
  • Automate repetitive administration and monitoring activities where practical, serve as an escalation point, and lead infrastructure initiatives from design through operational support.
  • Occasional travel and participation in after-hours maintenance, incident response, or on-call support may be required based on business and customer needs.

A "recently separated veteran" means any veteran during the three-year period beginning on the date of such veteran's discharge or release from active duty in the U.S. military, ground, naval, or air service.

An "active duty wartime or campaign badge veteran" means a veteran who served on active duty in the U.S. military, ground, naval or air service during a war, or in a campaign or expedition for which a campaign badge has been authorized under the laws administered by the Department of Defense.

Voluntary Self-Identification of Disability

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
