As the onsite System Administrator I, you’ll be the primary face of JMARK for many day‑to‑day technology needs at the client location. You’ll provide hands‑on and remote support, troubleshoot technical issues, maintain systems, and partner with other JMARK technical resources when additional expertise is needed.

• Basic VPN configuration and troubleshooting experience, including technologies such as Cisco and Meraki.
