Company Overview: At Lumbee Holdings, we deliver mission-critical logistical, technical, and analytical support to empower strategic government and defense operations. Our culture is built on continuous improvement, operational integrity, and dedicated service to key defense stakeholders. When you join our team, you become part of a collaborative environment where your expertise directly supports military readiness and system efficiency.

Your Role: As a Cybersecurity Engineer, you will deliver software assurance testing expertise and cybersecurity engineering support across both offensive assessment findings and independent engineering analysis for the MCTSSA Cyber Branch at Camp Pendleton, CA. You will serve as the team’s primary technical link between offensive findings and implementable engineering changes that make Marine Corps systems more survivable and defensible for Defensive Cyber Operations (DCO) operators. Your core focus includes static and dynamic code analysis, Security Posture Assessments, STIG hardening guidance, vulnerability mitigation engineering, and DCO integration.

  • Integrate DCO Systems & Playbooks: Assist in connecting program systems to designated DCO providers and produce DCO System Playbooks that outline incident response procedures.

  • Execute Scans & Vulnerability Management: Run ACAS vulnerability scans, analyze results, propose remediation actions, and monitor the ongoing application security posture for ISSM reporting.

  • Automate Security Tasks: Utilize PowerShell, JavaScript, or Python to automate repetitive cybersecurity engineering, analysis, and reporting tasks.

  • Investigate Cyber Incidents: Support breach investigations by analyzing multiple data sources to identify indicators of compromise (IoCs).

  • Author Technical Reports: Draft clear client reports explaining technical findings, engineering rationale, and remediation steps for non-technical Program Office stakeholders.

  • Coding & Scripting: At least one (1) year of experience developing code or scripts in languages such as Python, C/C++, Ruby, or PowerShell for automation and analysis.

  • IT Infrastructure Support: Hands-on experience in administration, configuration, and support of operating systems, network components, and application security.

  • Location/On-Site: Willingness and ability to work 100% on-site at Camp Pendleton, CA.
