Dev Sec Ops  / Systems Administrator

Clearance: Active Top Secret/SCI with CI Polygraph required

Salary Range: $210K–$228K

We are hiring an experienced Dev Sec Ops  / Systems Administrator to help build, secure, automate, and operate mission‑critical technology environments supporting national security objectives.

This is a hands‑on role at the intersection of Dev Sec Ops , systems administration, cybersecurity, cloud infrastructure, automation, and systems integration
. You’ll work across cloud, on‑premises, hybrid, and air‑gapped environments while ensuring security is integrated throughout the software development and operational lifecycle.

A key part of the role involves supporting the secure movement and processing of data—from front‑end applications through back‑end services and downstream systems—while maintaining the security, reliability, and compliance required in sensitive environments.

If you enjoy solving complex infrastructure and security challenges and working alongside multidisciplinary engineering teams, this role offers an opportunity to apply that expertise to systems where performance and security matter.

You’ll help integrate security throughout the software development lifecycle while improving the automation, security, and reliability of development and deployment processes.

You’ll:

• Design, implement, secure, and maintain CI/CD pipelines.
• Integrate security controls, testing, and best practices throughout the software development lifecycle.
• Automate application security testing, vulnerability scanning, compliance checks, and deployment activities.
• Incorporate security tools into development, build, testing, and release workflows.
• Assess the security of new and existing applications, systems, and infrastructure.
• Identify, prioritize, document, and support remediation of security vulnerabilities.
• Implement applicable security frameworks, policies, standards, and industry best practices.
• Monitor systems and infrastructure for vulnerabilities, security incidents, configuration issues, and emerging threats.
• Develop technical solutions that satisfy system‑security and data‑protection requirements.
• Establish and maintain Dev Sec Ops  procedures, technical standards, and security best practices.

You’ll work hands‑on with the infrastructure supporting development and operational systems.

You’ll:

• Build, configure, secure, administer, and maintain physical and virtual servers.
• Support cloud‑based, on‑premises, hybrid, and air‑gapped computing environments.
• Administer operating systems, system configurations, user access, permissions, patching, backups, and system availability.
• Implement and maintain encryption for data at rest and in transit.
• Monitor network, server, application, and infrastructure health, performance, reliability, and security.
• Troubleshoot complex system, network, application, integration, and deployment issues.
• Develop infrastructure‑as‑code solutions that create secure, consistent, and repeatable environments.
• Support system hardening, configuration management, change management, and lifecycle maintenance.
• Assist with the integration and administration of Cross Domain Solutions and other controlled data‑transfer technologies, as applicable.

You’ll help ensure information moves securely and reliably across interconnected systems and security boundaries.

You’ll:

• Design, implement, and support dataflow architectures that securely move information from front‑end systems through back‑end services and downstream processing environments.
• Analyze system interfaces, data dependencies, processing requirements, and security boundaries.
• Support secure data exchanges across applications, networks, cloud environments, and external systems.
• Partner with software, hardware, and systems engineering teams to integrate components and resolve technical dependencies.
• Ensure data‑handling solutions meet applicable security, encryption, access‑control, and operational requirements.

You’ll support the security authorization and compliance activities required to operate…
