On-Site Network Engineer – Facility Build-Out & Secure Hybrid Connectivity
Contract (through December 2026, extension likely) · On-Site: Denver, CO metro (Centennial / Louisville)
Overview
The Select Group is building out the network for a new manufacturing and engineering facility within a space technology and satellite systems company, — a site with a high-bay manufacturing floor, test equipment, purpose-built servers, and specialized devices used to configure and operate satellite systems. This role owns the physical network build: configuring all switching, routing, and firewalls in the facility, establishing the secure transport layer that connects the site to a new AWS environment and to a third-party satellite ground station provider, and operationalizing the network with configuration backup and recovery from day one. The facility network must be operational to support an end-of-October 2026 program milestone.
What You'll Do
-
Configure and deploy Arista switching across the facility, including two communications rooms on separate floors, connecting manufacturing equipment, test systems, servers, printers, and specialized program devices on a physically switched network.
-
Configure and deploy Palo Alto physical firewalls at the facility boundary, and a Palo Alto virtual firewall (VM-Series) in AWS as the cloud-side transport boundary, with appropriate redundancy.
-
Establish and manage all interconnections between environments: build and maintain the secure tunnel from the physical facility to AWS, and the secure tunnel from AWS to the third-party ground station provider.
-
Configure routing and upstream ISP connectivity for the site.
-
Operationalize every device from the start: automated nightly configuration backups stored in AWS, per-device disaster recovery, and the ability to push a stored configuration to a replacement unit (e.g., after an RMA) and bring it up quickly.
-
Direct port-level connectivity on site (patching devices into assigned switch ports); structured cabling, fiber runs, and inter-room pathways are handled by the client's facilities team and are out of scope for this role.
-
Coordinate closely with the AWS architect and integration engineer to validate end-to-end connectivity between the facility, the cloud environment, and external partners.
-
Align day to day with the client's network lead, with regular progress check-ins against the October milestone.
Required Qualifications
-
Strong hands-on enterprise network engineering experience: L2/L3 switching, routing, and firewall configuration in production environments.
-
Direct experience configuring Arista switching platforms.
-
Direct experience configuring Palo Alto firewalls, including both physical appliances and VM-Series virtual firewalls in AWS.
-
Experience designing and operating site-to-cloud and site-to-partner secure tunnels (IPsec/VPN) with redundancy.
-
Demonstrated operational discipline: configuration backup/restore workflows, device lifecycle and RMA replacement processes, and disaster recovery for network configurations.
-
Ability to work on site in the Centennial/Louisville area during the physical build-out phase.
-
U.S. Person with the ability to access CUI, ITAR, and Export Controlled data; must be able to pass a background check that includes insider threat screening.
Preferred Qualifications
-
Active or prior U.S. Government security clearance.
-
Experience supporting manufacturing, lab, or aerospace facility networks with specialized/purpose-built equipment.
-
Familiarity with AWS networking (VPCs, VPN gateways) sufficient to partner effectively with cloud engineers.
-
Network automation experience (e.g., config management, zero-touch provisioning) as the environment matures.
Logistics
-
On-site presence required for the physical network build-out; some follow-on work may be performed remotely on a client-furnished, authorized device.
-
Engagement runs through the end of 2026 with a hard facility-readiness milestone at the end of October; follow-on work is anticipated.
-
Wireless is present in the building but is not in scope for this phase; the program network is physical switching. No standing on-call, though brief scheduled support windows may occur around major program events (e.g., satellite launches).
