Principal Network Security Systems Engineer

As a Network Security Systems Engineer, you will leverage your deep expertise in network architecture, advanced security protocols, and DoD systems to inform the design, implementation, and defense of secure networks critical to national security. You will play a crucial role in the analysis and mitigation of vulnerabilities in software designs, development of innovative software security solutions, and the integration of secure coding practices and architectures for applications and systems.
Responsibilities:

• Provide expert technical guidance in the architecture, implementation, and security assessment of secure networks

• Guide comprehensive security audits, penetration testing, and risk assessments, proactively identifying vulnerabilities and developing sophisticated mitigation strategies

• Shape the design and implementation of cutting-edge security solutions, including multi-layered network segmentation and granular access controls, Zero Trust network architecture and micro-segmentation strategies, and robust cryptographic solutions for data protection

• Contribute to the development of technical requirements and specifications for secure network design in alignment with industry best practices, government regulations, and certification standards

• Collaborate with engineers and stakeholders to transition prototype security solutions into operational systems

• Proactively research and analyze emerging threats and vulnerabilities, staying ahead of adversaries to maintain a proactive security posture Requirements:

• Demonstrated expertise designing, implementing, and securing networks in a DoD or similar high-security environment

• Demonstrated experience in DoD network protocols and architectures, including relevant encryption standards and protocols (Type 1 devices, Suite A/B algorithms, FIPS 140-2 validation)

• Extensive knowledge of network encryption devices, key management concepts, and VPN technologies

• Strong foundation in core network security principles, routing protocols, and switching technologies

• Experience implementing and managing COMSEC solutions and cross-domain security controls

• Hands-on experience with intrusion detection/prevention systems (IDS/IPS), SIEMs, and other network monitoring tools

• Experience conducting security audits or developing assessments for compliance with DoD policies and regulations

• Proven ability to think critically, operate independently, and communicate effectively with both technical and non-technical stakeholders Preferred Qualifications:

• Extensive experience supporting DoD research and development programs

• Experience with cross-domain solutions, data diode technologies, and secure enclaves

• Advanced troubleshooting skills to diagnose and resolve complex network and encryption-related issues

• Experience with systems programming languages, particularly C, C , and Rust, and their application in network security

• Familiarity with cloud-based encryption solutions and their integration with DoD networks

• Industry-recognized cybersecurity certification (e.g., Security+, CISSP, CEH, CASP+) or a relevant networking certification (e.g., CCNA Security, CCNP Security) is desired Education:
• Bachelor's degree in cybersecurity, computer science, electrical engineering, or related field; or equivalent experience Clearance:
