  • Execute DR testing, runbooks, and recovery procedures in alignment with defined RTO/RPO targets

Governance, M&A & Reporting

  • Support infrastructure discovery, integration, and migration activities for M&A events
  • Maintain infrastructure documentation, standards, and audit evidence
  • Produce operational reporting on uptime, capacity, backup success, and cloud spend
  • Support compliance initiatives including SOC 2, NIST 800‑171, and CIS controls

  • 8–12+ years of progressive infrastructure experience with at least 3–5 years in a leadership or senior technical lead role

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.

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.
