• Ensure effective implementation and monitoring of NIST-based controls, including validation of technical, administrative, and operational safeguards.

• Provide oversight of DevSecOps integration efforts, ensuring security requirements are embedded within CI/CD pipelines, configuration-as-code, and policy-as-code practices.

• Guide secure design and implementation of cloud-based and hybrid architectures, ensuring adherence to Zero Trust and enterprise security principles.

• Lead cross-functional cybersecurity coordination across engineering, development, operations, and testing teams, promoting secure-by-design practices throughout the system lifecycle.

• Serve as the primary cybersecurity liaison to customer and stakeholder leadership within regulated or federal environments.

• Risk Management & Authorization: Demonstrated experience supporting system authorization processes, security control assessments, continuous monitoring, and audit readiness.

• Architecture & Infrastructure Security Oversight: Experience overseeing secure network and cloud architecture, ensuring required security posture at infrastructure and platform layers.

• Enterprise & Cloud Security Leadership: Experience applying Zero Trust principles and enterprise security best practices across cloud, containerized, and hybrid environments.

• Experience collaborating with engineering and development teams to integrate security requirements into Agile and DevSecOps workflows.

• Familiarity with security automation, continuous monitoring tools, and vulnerability management platforms.

• Strong knowledge of enterprise networking technologies and secure infrastructure operations.

• Experience supporting proposal development, including cybersecurity strategy contributions and Basis of Estimates (BOEs).

• Experience implementing and overseeing customer-specific NIST and FISMA compliance requirements within regulated environments.

• Experience supporting cloud-native and hybrid-cloud environments with integrated CI/CD security controls.
