Job Description

At Lockheed Martin Rotary and Mission Systems, we are shaping the future of defense and security through innovation, integrity, and visionary thinking. Our teams apply the highest standards of business ethics and technical expertise to design solutions that safeguard our nation and allies. Every day, we push boundaries to ensure mission success—and we invite you to be part of this critical work.

THE WORK

We are seeking a highly motivated Cyber Security Systems Engineer to support the design, implementation, hardening, and sustainment of secure mission systems across both CONUS and OCONUS environments. This role requires strong technical expertise in systems engineering, cybersecurity, infrastructure security, automation, and DevSecOps practices.

Key Responsibilities

• Design and implement secure system architectures for enterprise and mission-critical environments.
• Apply cybersecurity engineering principles across the full system lifecycle, including requirements, design, implementation, verification, deployment, and sustainment.
• Support Risk Management Framework (RMF) activities including control implementation, assessment, evidence collection, and ATO accreditation and sustainment.
• Perform security hardening of operating systems, applications, databases, and network devices in accordance with applicable security baselines (e.g., STIGs, CIS, vendor hardening guides).
• Develop and maintain system security documentation including RMF artifacts such as SSPs, architecture diagrams, SCTM, and POA&M.
• Identify security gaps and propose remediation strategies to reduce cyber risk.
• Support vulnerability management processes including scanning, triage, prioritization, and remediation tracking.
• Implement and maintain DevSecOps pipelines integrating automated security testing and compliance validation.
• Integrate tools such as SAST, DAST, container scanning, IaC scanning, and software composition analysis into CI/CD workflows.
• Automate security control validation and compliance reporting using scripting and infrastructure automation tools.
• Collaborate with cross-functional teams to ensure secure software delivery and continuous compliance.
• Support incident response, remediation efforts, engineering roadmaps, and cyber resilience planning when required.
• Travel or deploy to CONUS and OCONUS locations based on mission requirements.

WHAT WE'RE DOING

This position requires a DoD government clearance at the Secret level. This position is based out of King of Prussia, PA or Colorado Springs, CO and the willingness to deploy OCONUS. This position supports both office and field/deployed environments. Candidates must be comfortable working in operationally demanding settings, including secure facilities and OCONUS deployments.
