Network Engineer

General Matter is enriching uranium in America. 

Our goal is to design, build, and operate the world’s lowest-cost enrichment services in the United States.  

Our mission is to restore America’s ability to produce nuclear fuel—fuel that will power AI, advanced manufacturing, critical industries, and the next generation of nuclear reactors. 

Ultimately, our work will help power national ambitions and enable a high-energy society. 

We were incubated by Founders Fund, like Anduril and Palantir before us, and are backed by top-tier investors. Our lean, world-class team of engineers and operators is applying a first-principles approach to solving the problem of nuclear fuel production.  

We are a mission-driven company with a culture of urgency, accountability, and transparency. 

Help us build a high-energy society by making the cleanest, safest form of baseload energy the most affordable. 

We’re looking for an experienced Network Engineer to design, implement, and operate the network infrastructure that connects our people, systems, and facilities. This is a hands-on, high-ownership role — you’ll architect, deploy, and manage everything from fiber-connected multi-building networks to secure, air-gapped environments supporting engineering, manufacturing, and compute-intensive workloads.

You’ll collaborate closely with systems, security, and engineering teams to ensure our networks are fast, reliable, and built for scale. This role includes helping design and optimize high-performance compute (HPC) clusters, ensuring low-latency, high-throughput connectivity for simulation and engineering workloads.

It’s an opportunity to own foundational infrastructure in a high-growth, technically demanding environment — where precision, reliability, and scalability are key.

• →Design, deploy, and maintain enterprise and lab networks spanning multiple buildings and facilities.
• →Architect and operate air-gapped and isolated networks with strict segmentation, access control, and security monitoring.
• →Collaborate with systems and engineering teams to design and optimize high-performance compute (HPC) clusters and their supporting network infrastructure.
• →Configure and manage switching, routing, wireless, and firewall systems (Cisco, Fortinet, Juniper, or Unifi).
• →Implement and maintain fiber-based WAN connectivity between buildings and remote sites.
• →Manage LAN/WAN infrastructure, including VLANs, VPNs, DNS, DHCP, and QoS configurations.
• →Integrate on-prem and cloud networking to support Azure and Microsoft 365 hybrid environments.
• →Deploy and maintain network monitoring and alerting systems (e.g., PRTG, SolarWinds, Grafana, NetBox, Datadog).
• →Develop resilient architectures with redundancy, observability, and security built in.
• →Collaborate across IT, security, and engineering teams to support high-performance and secure operations.
• →Document network designs, configurations, and operational procedures following ITSM and change management best practices.
• →Troubleshoot and resolve complex networking issues across physical and virtual environments.

• 5+ years of experience as a Network Engineer or equivalent technical role.
• Proven experience designing and operating multi-building or campus networks.
• Strong knowledge of fiber WAN, switching, routing, and firewalls (Cisco, Fortinet, Juniper, or Unifi).
• Experience building and maintaining air-gapped or segmented network environments.
• Familiarity with high-performance compute (HPC) or other low-latency networking systems.
• Proficiency with network monitoring, diagnostics, and alerting tools.
• Deep understanding of TCP/IP, VLANs, VPNs, routing protocols, DNS, DHCP, and network security.
• Excellent troubleshooting, documentation, and communication skills.
• Ability to take full ownership — from architecture to hands-on implementation and operations.

• Experience in aerospace, defense, or other regulated technical operational environments (e.g., GCC High, FedRAMP).
• Familiarity with Zero Trust, SDN, or network automation concepts.
• Scripting and automation skills using Python, Ansible, or PowerShell.
• Exposure to ITSM, incident/change management, and configuration control processes.
• Certifications such as CCNP, Fortinet NSE, Juniper JNCIP, or equivalent.

• Ability to work extended hours and weekends as necessary.
