Comparable experience may come from organizations such as Verizon, Altice/Optimum, Charter Communications, Zayo, Crown Castle, Windstream, or legacy Level 3 environments.

Technical or vocational training in electronics, telecommunications, networking, or a related discipline is preferred.

Military candidates with hands-on experience in communications, electronics, telecommunications systems, signal systems, or network infrastructure are also strongly encouraged to apply.
