Cyber Engineer; Digital Ecosystem

At PMAT, we work on mission critical systems that directly support the warfighter, designing, building, and securing modern digital capabilities across cloud, data, and software environments. Our teams tackle complex, real-world challenges where delivery matters more than theory, and innovation is driven by curiosity, collaboration, and purpose.

In this role, you’ll contribute to Naval Operational Architecture (NOA), working alongside engineers and operators to deliver resilient, forward-leaning solutions in support of national defense.

PMAT is seeking a highly experienced Cyber Engineer to support the design, automation, security, administration, and sustainment of secure mission-critical environments across development, production, classified, cloud, containerized, and Dev Sec Ops -enabled systems. This role focuses on improving software and infrastructure security posture through vulnerability management, automated security pipelines, container hardening, system hardening, compliance support, and secure infrastructure operations. The candidate will work closely with cybersecurity, software development, infrastructure, platform, engineering, and mission stakeholders to reduce vulnerabilities, implement mitigations, support authorization activities, and maintain secure and reliable environments throughout the development, accreditation, and operational lifecycle.

The role requires strong hands‑on technical capability, cybersecurity judgment, automation experience, and the ability to communicate security risks and remediation strategies across technical and program audiences.

• Design, implement, and improve security automation pipelines within Dev Sec Ops  environments by supporting CI/CD integration, automated vulnerability scanning, container security checks, remediation workflows, and secure software delivery practices.
• Support vulnerability management across production, development, cloud, containerized, and classified environments by identifying, tracking, prioritizing, documenting, and remediating findings in accordance with cybersecurity requirements and ISSM-approved timelines.
• Manage and document Plans of Action and Milestones for security findings by maintaining visibility of vulnerability status, remediation progress, risk acceptance considerations, and continuous burndown of medium-level findings.
• Develop and implement mitigations for identified vulnerabilities by applying secure configuration changes, system hardening, patching, container hardening, access control improvements, and infrastructure security enhancements.
• Support the design, administration, and sustainment of secure infrastructure stacks across Linux, Windows Server, virtualization, private cloud, enterprise services, network infrastructure, and containerized environments.
• Implement and remediate security controls in alignment with NIST SP 800-53, DISA STIGs, RMF, ATO, Zero Trust, secure software development lifecycle practices, and other applicable government cybersecurity requirements.
• Support infrastructure and cybersecurity automation by using scripting, configuration management, Infrastructure as Code, and automation tools to streamline system builds, patching, hardening, monitoring, and compliance activities.
• Collaborate with cybersecurity, software, infrastructure, networking, platform, program, and mission stakeholders to troubleshoot complex technical issues, improve security best practices, support accreditation efforts, and communicate risks, dependencies, and recommendations.
