• Hands-on experience with RMF and Authority to Operate (ATO) processes, including control implementation, documentation in eMASS, and assessor support.
• Hands-on experience with identity federation (including CAC/PKI or PIV-based authentication), zero trust architecture, encryption, network security, and SaaS integrations.
• Experience designing secure APIs, enterprise integrations, and data exchange architectures.
• Ability to document technical decisions, communicate architecture risks, and collaborate across engineering and security teams.
• U.S. citizenship.

Preferred Qualifications

• Experience integrating Workday or another enterprise human capital management platform.
• Experience supporting U.S. Space Force or Department of the Air Force modernization programs.
• Familiarity with the DoW Cloud Computing Security Requirements Guide (CC SRG), NIST SP 800-53, and applicable DISA STIGs and SRGs.
• Cloud architecture or security certifications (e.g., AWS or Azure architect or security credentials), or equivalent demonstrated expertise.
• Experience transitioning SBIR, prototype, or pilot capabilities into production government environments.
• Experience with AWS GovCloud or Azure Government, Cloud Access Point (CAP) connectivity, and CSSP onboarding.
