  • Support incident response activities, including documentation, tracking, and lessons learned.
  • Facilitate collaboration across IT, cybersecurity, engineering, and external stakeholders.
  • Provide guidance on cybersecurity best practices, policy interpretation, and secure configuration requirements.
  • Assist with continuous monitoring activities and ongoing authorization considerations.

  • Experience supporting SSPs, POA&Ms, security policies, risk assessments, or other GRC deliverables.
  • Understanding of common cybersecurity technologies, including IAM/MFA, endpoint security, SIEM logging, and vulnerability management.
  • Ability to interpret security requirements and work with technical staff to validate control implementation.
  • Strong organizational skills and attention to detail for handling security documentation and compliance artifacts.
  • Excellent communication skills, including the ability to translate technical controls into clear documentation.
  • Experience supporting internal audits, external assessments, or compliance readiness activities.
  • Familiarity with cloud security concepts (Azure, AWS) and modern enterprise IT environments.
  • 2–4 years of cybersecurity, GRC, systems security, or compliance experience.
  • CompTIA Security+, CySA+, CISA, or similar certifications desired; RMF or CMMC experience highly valued.
  • Ability to hold and maintain a security clearance.

What You’ll Get

  • Ownership – Play a pivotal role in shaping cybersecurity compliance and risk management efforts across the organization
  • Collaboration – Partner across engineering, IT, and security teams while expanding your technical and GRC expertise

Voluntary Self-Identification of Disability

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005
Expires 07/31/2029

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.
