Network Engineer

Allen Control Systems•Austin, TX

About The Position

We are seeking an experienced Network Engineer to own and secure the network infrastructure supporting a fast-moving defense engineering organization. This engineer will be responsible for the design, implementation, and reliability of both on-premises and cloud network environments, ensuring performance, security, and compliance in a regulated defense setting. Working closely with IT, security, and engineering teams, this individual will serve as the organization’s primary network resource, building infrastructure that supports rapid growth while meeting the demands of a security-sensitive environment. The ideal candidate is comfortable operating independently, enjoys solving complex network problems, and understands how to translate best practices into a resilient, well-documented network.

Requirements

5+ years of experience as a Network Engineer or Network Administrator, with hands-on responsibility for production network environments.
Demonstrated experience managing both on-premises network infrastructure (routing, switching, firewalls, WAN/LAN, wireless) and cloud networking in AWS (VPC, subnets, security groups, VPN/Direct Connect, Transit Gateway).
Proven experience designing and implementing network segmentation for regulated, security-sensitive, or compliance-driven environments.
Strong working knowledge of firewall administration and policy management (Palo Alto, Fortinet, Cisco ASA, or similar).
Experience troubleshooting complex, multi-site network issues independently — this role won’t have a second network engineer to lean on initially.
Solid documentation discipline: network diagrams, IP schemas, configuration baselines, change records.

Nice To Haves

CCNP certification (Enterprise, Security, or Data Center track).
Prior network engineering experience in aerospace, defense, or another ITAR/CMMC-regulated industry.
Familiarity with CMMC 2.0 / NIST 800-171 network boundary and CUI segmentation requirements.
AWS Certified Advanced Networking – Specialty, or equivalent AWS networking credential.
Experience with Infrastructure-as-Code (Terraform) for network provisioning.

Responsibilities

Own and maintain production network environments, spanning both on-premises infrastructure (routing, switching, firewalls, WAN/LAN, wireless) and cloud networking in AWS (VPC, subnets, security groups, VPN/Direct Connect, Transit Gateway).
Design and implement network segmentation strategies for regulated, security-sensitive, and compliance-driven environments.
Administer and manage firewall policies (Palo Alto, Fortinet, Cisco ASA, or similar) to protect network boundaries and enforce access controls.
Independently troubleshoot complex, multi-site network issues as the organization’s primary network engineering resource.
Maintain rigorous documentation, including network diagrams, IP schemas, configuration baselines, and change records.
