VAE, Inc. designs, deploys, and sustains mission-critical enterprise IT environments supporting federal customers. We’re seeking an experienced Senior Network Engineer who enjoys hands-on technical work, takes ownership of complex environments, and can operate independently while collaborating with a small, high-performing engineering team.
This role is ideal for a seasoned engineer who prefers deep technical responsibility over people management and values long-term stability in a secure environment.
What You’ll Do
Design, implement, and sustain enterprise network infrastructures supporting high availability and mission operations
Serve as a senior technical resource for network troubleshooting, outage resolution, and performance optimization

Configure and support next-generation firewalls, including Juniper SRX and Cisco Firepower platforms
Support firewall rule management, policy validation, and traffic-flow troubleshooting across secured boundaries
Maintain accurate technical documentation, diagrams, and standard operating procedures
Participate in planning and implementation of network upgrades and architectural improvements
Ensure compliance with DoD security and configuration standards
Why This Role
Own and influence a mission-critical enterprise network, not just tickets
Work in a stable, security-focused environment with long-term programs
Be part of a small, senior engineering team where expertise is valued
Opportunity to deepen skills in network security, access control, and boundary protection
Qualifications
8+ years of hands-on network engineering experience in enterprise or government environments
Strong understanding of TCP/IP, IPv4, routing, switching, and network troubleshooting
Proven experience with Cisco and/or Juniper network devices
Hands-on experience configuring and administering Cisco ISE
Experience supporting Juniper SRX firewalls and Cisco Firepower (FMC-managed)
Strong understanding of firewall policies, security zones, and traffic inspection
Familiarity with DoD STIGs and operating in compliance-driven environments
CCNA, CCNP, JNCIS, or JNCIP certification (active or previously held)
Ability to work on-site in Washington, DC (5 days per week)
Active Top Secret clearance (required to start)
DoD 8570 IAT Level II certification (Security+ or equivalent)
Desired (Nice-to-Have) Skills
Experience integrating Cisco ISE with 802.1X, TACACS+, or network access control workflows
