Network Infrastructure Engineer

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.
