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 CACIs development and IT teams to integrate security best practices identify and mitigate security vulnerabilities and ensure compliance with industry standards. Youll 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.

The proposed salary range for this position is:

$108400 - 227500 USD
