Network Engineer

Network Engineer Hawthorne, CA $140K-$170K Permanent About :The Company are restoring America's ability to produce nuclear fuel. They design, build, and operate domestic uranium enrichment infrastructure — fuel that will power AI, advanced manufacturing, and the next generation of nuclear reactors . Incubated by Founders Fund and backed by top-tier investors, they are a lean team of engineers and operators applying first-principles thinking to one of the most critical challenges in energy and national security. They move fast, hold themselves accountable, and build things that matte r. The Ro le:They are looking for a hands-on Network Engineer to own the infrastructure that connects their people, systems, and facilities. You'll design and operate everything from fiber-connected multi-building campus networks to secure, air-gapped environments supporting engineering, manufacturing, and high-performance compute workloa ds.
