Thank you for your interest in joining our team as we work to ensure a smooth transition and continuity of mission support.

If you’re a current DDSB incumbent, you may notice some differences in the listed education and certification requirements. These changes are likely due to the DoD’s transition from the 8570 framework to the updated 8140 policy.
