Network Engineer

Overview In this role you will own the design, architecture, and reliability of Hadrian’s global network across data centers, campuses, multi-site, and cloud environments. You’ll set standards, drive scalable topologies, and lead site bring-ups from design to production, partnering with infrastructure, IT, security, and operations. You will shape network architectures that scale beyond a single site while enabling 24/7 manufacturing operations. This is a hands-on, high-impact role at the intersection of industrial tech and networking, with a clear opportunity to influence how Hadrian connects facilities and cloud resources at scale.
