Itsm Engineer Jobs in California (NOW HIRING)

About the Company

General Matter enriches uranium.

We are designing, building, and operating the world's lowest-cost enrichment services, here in the US.  

In the process, we are restoring America's ability to produce nuclear fuel to power AI, advanced manufacturing and critical industries our country relies on to remain competitive. 

Fuel drives the cost of advanced reactor electricity production, and enrichment drives the cost of the fuel that advanced reactors consume.  Reliable, low-cost enrichment is the catalyst for the nuclear Renaissance now under way.

Our mission is to make nuclear not only the cleanest and safest source of baseload power, but also the most affordable.  We believe abundant nuclear energy will lead to a post-scarcity society. 

We were incubated inside Founders Fund, like Anduril and Palantir before us, and are backed by over a dozen of the world's top venture capital firms.  

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. 

About This Role

We're looking for an experienced Network Infrastructure 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.

Responsibilities

• 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.

Basic Qualifications

• 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.

Preferred Skills and Experience

• 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.

Additional Requirements

• Ability to work extended hours and weekends as necessary.
