Build More Than Just a Career. Build Your Future.
At Vailexa, we’re not just hiring — we’re building thinkers, creators, and future leaders.
We believe in giving people the space to grow, the freedom to think, and the opportunity to create real impact from day one. If you’re someone who wants to learn fast, take ownership, and grow beyond limits, you’ll feel right at home here.
Overview
We are seeking a Senior Network Engineer to design, implement, secure, and support enterprise network infrastructure across LAN/WAN/WiFi, datacenters, and cloud connectivity within a CMMC-regulated environment. This role requires deep technical expertise in enterprise networking plus hands-on experience supporting NIST 800-171 controls and CUI (Controlled Unclassified Information) boundary protection.
Key Responsibilities
•
Design, implement, and maintain enterprise network infrastructure (LAN/WAN/WLAN) in alignment with CMMC/NIST 800-171 requirements.
•
Lead the design and implementation of Cisco SD-Access (SDA) across the environment, including DNA Center-managed fabric (wired and wireless), SGT/TrustSec-based segmentation, and fabric-based CUI boundary enforcement.
•
Manage and optimize routing and switching environments (SD-WAN, BGP, OSPF, EIGRP, VLANs, STP, HSRP/VRRP).
•
Configure and support firewalls, VPNs, and network security controls enforcing CUI boundary segmentation.
•
Design and maintain network architecture supporting CUI enclaves, including access control, encryption in transit, and audit logging per NIST 800-171 / DFARS 252.204-7012.
•
Lead network upgrades, migrations, and infrastructure projects with attention to compliance boundary impact.
•
Support and troubleshoot network performance issues and outages (root cause analysis).
•
Monitor network health using tools like SolarWinds / ThousandEyes (or similar), including compliance-relevant traffic visibility and alerting.
•
Maintain network documentation: diagrams, IP schema, standards, runbooks, and System Security Plan (SSP) network artifacts.
•
Support CMMC self-assessment or C3PAO assessment activities by providing network evidence, diagrams, and control narratives.
•
Work with service providers for circuit turn-ups, troubleshooting, and escalations.
•
Ensure high availability, redundancy, and disaster recovery readiness.
•
Mentor junior engineers and provide technical guidance.
•
Participate in on-call rotation and after-hours maintenance.
Implement cloud segmentation and secure routing patterns specifically for CUI-handling workloads.
•
Support cloud security integrations: centralized logging/monitoring, network traffic visibility and alerting mapped to NIST 800-171 controls.
•
Partner with cloud engineering and compliance/GRC teams to ensure compliant connectivity for CUI workloads.
Required Qualifications
•
Bachelor’s degree in IT/Computer Science or equivalent experience.
•
7+ years of hands-on enterprise network engineering experience.
•
Demonstrated experience supporting a network environment under CMMC / NIST 800-171 / DFARS 252.204-7012 requirements — implementation or assessment support, not just familiarity.
•
Strong knowledge of routing and switching (Cisco); TCP/IP, subnetting, DNS, DHCP, InfoBlox; WAN technologies (DMVPN, SD-WAN, DIA, broadband); wireless networking (Cisco/Meraki).
•
Experience with firewalls (Palo Alto / Cisco ASA/FTD), VPN (site-to-site, remote access), and network segmentation for regulated/CUI environments.
•
Strong troubleshooting skills using packet capture tools (Wireshark/tcpdump).
•
Experience contributing to or supporting SSP, POA&M, or CMMC assessment documentation.
•
Excellent communication and stakeholder management skills.
Preferred Qualifications
•
CMMC RP, CCP, or CCA credential (or actively pursuing).
