Senior Network Engineer, Remote. USA
About The Position
We're looking for a Senior Network Engineer who enjoys solving complex technical challenges, designing resilient infrastructure, and taking ownership of networking from architecture through to automation. This is a fully remote position for candidates based in the United States, with very rare but occasional travel to our offices in Denver, Colorado, or Magor, Wales (UK). You'll join a small, highly skilled infrastructure team responsible for designing, deploying and supporting secure, high-performance networks that power globally distributed operations. Much of our work takes place in specialist environments where reliability, security and performance are critical. While some projects are confidential, you'll work with modern networking and security technologies on infrastructure that supports mission-critical services around the world. This isn't a role where you'll spend your days resetting switch ports or chasing tickets. You'll have the freedom to influence designs, automate repetitive tasks, solve challenging networking problems and help shape the future of our infrastructure.
