Position Summary:

As a Senior Network Engineer, you will maintain and secure network STIG baselines, enforce vulnerability hardening, and verify sensor compliance across multiple classified enclaves. Your mission will directly support accreditation requirements and operational readiness for critical national security programs. Applying a mission-first, people-always mindset with zero tolerance for mission failure, you will drive robust network engineering practices, implement hardening guides, and deliver resilient, secure network infrastructure to support the highest levels of mission assurance.

Responsibilities:

• Apply secure configurations to routers, switches, firewalls, sensors, and IDS/IPS appliances; document and manage exceptions, waivers, and risk acceptance decisions.

• Perform regular vulnerability assessments using tools such as ACAS, Nessus, or OpenVAS; track findings in POA&Ms and coordinate timely remediation.

• Deploy and validate firmware patches and security updates for network devices and security sensors with minimal mission downtime.

• Validate compliance of security sensors (Zeek, Suricata, NetFlow, custom taps) to confirm coverage, logging fidelity, and encryption effectiveness.

• Maintain configuration baselines using Git, Ansible, or other infrastructure-as-code approaches to ensure consistent, auditable, and secure device builds.

• Collaborate with ISSO/ISSM staff to generate RMF artifacts (SSP, SAR, POA&M) and sustain ATO accreditation.

• Troubleshoot complex Layer 1–4 networking issues, optimize routing protocols (OSPF, BGP), and enforce segmentation and access controls consistent with zero-trust architecture.

• Provide mentoring, coaching, and knowledge transfer to junior engineers on secure-network design, STIG compliance, and mission-focused resilience.

Required Qualifications:

• Eight plus (8+) years of hands-on network engineering experience supporting classified or mission-critical secure environments.

• Deep expertise configuring Cisco, Juniper, or Arista platforms and applying DISA STIGs and other relevant hardening baselines.

• Hands-on experience with vulnerability-assessment tools and patch-management processes.

• Solid understanding of core networking principles, including TCP/IP, VLANs, VPNs, IDS/IPS architecture, and high-availability designs.

• Excellent ability to produce clear technical documentation and brief security findings to mission and program leadership.

• Demonstrated commitment to mission-first, people-always values with zero tolerance for mission failure.

Preferred Qualifications:

• Bachelor’s degree in Computer Science, Data Science, Electrical Engineering, or a related technical field.

• Certifications such as CCNP Security, JNCIS-SEC, or CISSP.

• Experience automating network compliance tasks with Ansible, Terraform, or SaltStack.

• Familiarity with secure cloud-networking patterns (AWS GovCloud, Azure GCC) and hybrid security architecture.

• Background integrating advanced AI/ML-driven detection or enrichment feeds into traditional NIDS frameworks.

Clearance Requirement:

• Active TS/SCI with Poly

Salary Range:

• $175K-$192K (Salary commensurate with experience)
