  • Develop and enforce internal baseline configuration guides, utilizing DISA STIGs and CIS Benchmarks across company-built hardware appliances, software stacks, and operating environments.

  • Evaluate internal product architectures and software deliverables for security posture, facilitating static/dynamic code analysis, dependency scanning, and zero-trust alignment.

  • Establish company-internal cybersecurity standard operating procedures (SOPs), hardening checklists, and secure development guidelines to ensure consistency across product lines.

  • Lead protective and corrective measures upon discovery of critical vulnerabilities or zero-day threats affecting deployed customer networks or company solutions.

  • Coordinate with government security leadership and internal teams to report, contain, investigate, and remediate potential security incidents or policy non-compliance.

  • Coordinate and prepare systems for formal government cybersecurity inspections, and internal quality audits.

  • Advise internal engineering managers and government leadership on security posture, mission risk trade-offs, and emerging cybersecurity threats.

  • Translate complex government compliance requirements (DoDI 8510.01, NIST guidelines) into actionable technical requirements for internal development teams.
