Network Infrastructure Engineer

About the Company

General Matter is engaged in the enrichment of uranium. The company is designing, building, and operating what it describes as the world's lowest-cost enrichment services within the United States. This work is intended to restore America's capacity to produce nuclear fuel, with the stated purpose of powering artificial intelligence, advanced manufacturing, and other critical industries essential for national competitiveness. Leadership asserts that reliable, low-cost enrichment acts as a catalyst for a nuclear renaissance. The company's mission is to make nuclear energy the cleanest, safest, and most affordable source of baseload power, with the broader goal of contributing to a post-scarcity society. General Matter was incubated within Founders Fund, similar to Anduril and Palantir, and is backed by over a dozen of the world's top venture capital firms. The team describes itself as lean and world-class, applying a first-principles approach to nuclear fuel production.

About the Role

The role is for a Network Infrastructure Engineer responsible for designing, implementing, and operating the network infrastructure that connects personnel, systems, and facilities. It is described as a hands-on, high-ownership position involving the architecture, deployment, and management of network environments. These environments range from fiber-connected multi-building networks to secure, air-gapped setups that support engineering, manufacturing, and compute-intensive workloads. The position requires close collaboration with systems, security, and engineering teams to ensure networks are fast, reliable, and scalable. A key focus is designing and optimizing high-performance compute (HPC) clusters to achieve low-latency and high-throughput connectivity for simulation and engineering workloads. The role is situated in a technically demanding, high-growth environment where precision, reliability, and scalability are paramount.

What You'll Do

• Design, deploy, and maintain enterprise and laboratory networks that span multiple buildings and facilities.
• Architect and operate air-gapped and isolated networks, implementing strict segmentation, access control, and security monitoring.
• Collaborate with systems and engineering teams to design, optimize, and support high-performance compute (HPC) clusters and their network infrastructure.
• Configure and manage network components including switching, routing, wireless, and firewall systems from vendors such as Cisco, Fortinet, Juniper, or Unifi.
• Implement and maintain fiber-based wide area network (WAN) connectivity between buildings and remote sites.
• Manage LAN/WAN infrastructure components, including VLANs, VPNs, DNS, DHCP, and Quality of Service (QoS) configurations.
• Integrate on-premises and cloud networking environments to support hybrid deployments using Azure and Microsoft 365.
• Deploy and maintain network monitoring and alerting systems, including tools such as PRTG, SolarWinds, Grafana, NetBox, and Datadog.
• Develop resilient network architectures that incorporate redundancy, observability, and security by design.
• Collaborate across IT, security, and engineering teams to support high-performance and secure operational requirements.
• Document network designs, configurations, and operational procedures in alignment with ITSM and change management best practices.
• Troubleshoot and resolve complex networking issues across physical and virtual environments.

Requirements

• 5+ years of professional experience as a Network Engineer or in an equivalent technical role.
• Proven ability to design and operate multi-building or campus network environments.
• Strong knowledge of fiber WAN technologies, switching, routing, and firewall systems, including Cisco, Fortinet, Juniper, or Unifi platforms.
• Experience building and maintaining air-gapped or segmented network environments with strict security protocols.
• Familiarity with high-performance compute (HPC) or other low-latency networking systems.
• Proficiency with network monitoring, diagnostics, and alerting tools.
• Deep understanding of core networking technologies, including TCP/IP, VLANs, VPNs, routing protocols, DNS, DHCP, and network security fundamentals.
• Excellent troubleshooting, documentation, and communication skills necessary for managing complex infrastructure.
• Ability to take full ownership of network initiatives, covering architecture, hands-on implementation, and ongoing operations.

Nice to Have

• Experience working in regulated technical environments such as aerospace, defense, GCC High, or FedRAMP.
• Familiarity with Zero Trust, Software-Defined Networking (SDN), or network automation concepts.
• Scripting and automation skills using languages and tools such as Python, Ansible, or PowerShell.
• Exposure to ITSM processes, incident and change management, and configuration control procedures.
• Industry certifications such as CCNP, Fortinet NSE, Juniper JNCIP, or equivalent credentials.

Practical Notes

• The position is based in Los Angeles, California.
• The engagement is full-time, with eligibility for full-time employment and benefits for qualified candidates.
• Compensation for this role has a base salary range of $110,000-$170,000 annually.
• Ability to work extended hours and weekends may be required as part of operational needs.
