We are seeking a highly skilled and certified Sr Network Security Architect with a robust background in designing, configuring, deploying, managing, and enhancing network security architectures within complex and distributed enterprise environments. This role demands the capability to resolve intricate technical challenges both independently and collaboratively. This role will directly consult with and advise customer engineering leads on projects in architecture, administration, engineering, and operations for an array of solutions and platforms. Additionally, this position involves informing clients of best practices, identifying cost savings opportunities by integrating existing capabilities, and identifying opportunities to leverage emerging technologies for added value.
Key Responsibilities
- Serve as the lead architect and subject matter expert (SME) for enterprise network security strategy, design, and implementation across on-premises, hybrid, and cloud environments.
- Design and implement zero trust architecture (ZTA) principles, including identity-centric access controls, micro-segmentation, continuous validation, and least-privilege enforcement.
- Develop and maintain defense-in-depth architectures that integrate network, system, identity, application, and cloud security controls into a cohesive security posture.
- Lead secure network segmentation strategies (macro and micro-segmentation) to reduce attack surface and lateral movement.
- Define and enforce network security standards, reference architectures, and technical baselines aligned to NIST, RMF, FedRAMP, and DoD security requirements.
- Provide architectural oversight for a variety of network security technologies, including firewalls, IDS/IPS, NAC, PKI, DLP, SWG, WAF, DNSSEC, RBI, email security (SPF, DKIM, DMARC, DANE, MTA-STS), DDoS protection, etc.
- Design secure connectivity solutions including VPN, SD-WAN, ZTNA, policy-based routing, dynamic routing (BGP/OSPF), and encrypted transport mechanisms (IPSEC, MACSEC, TLS).
- Collaborate with external teams and mission partners to identify redundant systems, streamline security tooling, and implement consolidated solutions that improve efficiency and reduce operational costs.
- Lead proof of concept (POC) efforts, technical evaluations, and analysis of alternatives (AoA) for emerging security technologies.
- Guide the transition of architectures from concept to production, ensuring scalability, resilience, and operational sustainability.
- Support authority to operate (ATO) efforts under NIST RMF, including implementation of NIST 800-53 controls, security documentation artifacts, and system accreditation packages.
- Provide expert-level troubleshooting and conduct root cause analysis (RCA) for complex security and network incidents.
- Lead complex network and security troubleshooting efforts, performing packet-level analysis to diagnose issues across the full technology stack and drive rapid, root-cause resolution.
- Mentor engineers and contribute to the development of internal best practices and architectural playbooks.
Required Qualifications
- Bachelor’s degree in computer science, engineering, information systems, cybersecurity, or related field (or equivalent experience).
- 8+ years of experience in network security engineering and architecture, including enterprise and federal environments.
- Demonstrated experience designing and implementing zero trust and defense-in-depth architectures.
- Strong understanding of NIST RMF, NIST SP 800-53, FedRAMP, and DoD cybersecurity frameworks.
- Exceptional written and verbal communication skills with the ability to brief technical and executive stakeholders.
- Active DoD security clearance.
- CISSP, CCSP, CCNP/CCIE Security, or equivalent certification.
