  • Collaboration: Work closely with cross-functional teams to integrate security into all phases of the development lifecycle. Provide expert-level security guidance and support to engineering teams.

  • Testing and Evaluation: Perform Test and Evaluation (T&E); interview system SMEs; validate physical controls; review HW/SW lists; assess topology and TPPS. Additionally, document and provide on-site assessments.

  • Continuous Improvement: Stay current with the latest security trends, threats, and technologies related to Kubernetes and container orchestration. Recommend and implement improvements to enhance the security posture of Kubernetes (OpenShift) and DoD cloud environments.
