The Opportunity

CACI is seeking a skilled Cyber Security Engineer to support the design, implementation, and maintenance of secure systems and networks. The successful candidate will work closely with CACI's development and IT teams to integrate security best practices, identify and mitigate security vulnerabilities, and ensure compliance with industry standards. You’ll contribute to strengthening the security posture of critical infrastructure and systems supporting CACI operations.

• Translate RMF categorization results and applicable control baselines into implementable, testable system security requirements allocated across hardware, software, network, and inherited common controls.
• Design security architectures and control implementations that satisfy authorization requirements while meeting mission performance, integration, and sustainment constraints.
• Develop and maintain security architecture artifacts, authorization boundary diagrams, data flow diagrams, hardware/software lists, and PPSM registrations.
• Analyze ACAS/Nessus and STIG/SCAP results at the engineering level to separate genuine risk from finding noise and drive the remediate / mitigate / risk-acceptance decision.
• Evaluate candidate security solutions against mission need, integration complexity, sustainment burden, and authorization impact; produce recommendations with defensible tradeoff analysis.
• Serve as technical authority for control implementation decisions, including tailoring rationale, compensating controls, and inheritance strategy from common control providers.
• Provide security-focused insights and technical direction for network, infrastructure, and system architecture.
• Translate and communicate technical risks and requirements between technical and non-technical stakeholders.
• Research and evaluate emerging security technologies and practices and assess their applicability and authorization impact for our environments.
• Office Location for this Opportunity is in: Austin, TX

Responsibilities

• Collaborate with cross-functional engineering teams to design, implement, and sustain secure system architectures across the development and delivery lifecycle.
• Embed security into engineering processes, design reviews, configuration baselines, build pipelines, and delivery gates rather than assessing it after the fact.
• Provide security engineering input to modernization efforts including cloud migration, Zero Trust architecture alignment, containerization, and automation of compliance evidence generation.
• Maintain and enhance internally developed security tooling and automation to ensure it adheres to best practices and meets evolving cybersecurity standards.
• Develop and maintain security engineering standards, guidelines, and reference patterns for reuse across programs and systems.
• Mentor junior engineers and ISSOs on control implementation, assessment preparation, and secure design principles.

• Demonstrated expertise in cybersecurity engineering activities, including security architecture development, vulnerability assessment, risk assessment, and remediation planning.
• Experienced in hardening operating systems (Windows Server, RHEL/Linux) and applications to align with STIG requirements and compliance obligations.
• Hands-on proficiency with enterprise networking, network segmentation and boundary protection, and virtualization platforms.
• Scripting and automation capability (Python, PowerShell, Bash) sufficient to build tooling and automate compliance evidence collection.
• Ability to read system and software design documentation and independently identify security implications and control gaps.
• Proficient in security toolsets, including vulnerability assessment platforms (Nessus/Tenable Security Center, ACAS), SIEM platforms, and endpoint security tooling.
• Exceptional problem-solving abilities with a proactive approach to identifying and mitigating security risks.
• Ability to work independently and within a team, adapting to dynamic security challenges.

Desired

Preferred Experience
