When NATO stands up its Security Assistance and Training for Ukraine mission, the network underneath has to simply never fail. NSATU needs a senior Cisco engineer to provide the Level-3 routing and switching expertise that keeps that network available, secure and fast, across permanent and deployable environments reaching into Poland, Romania and Slovakia.

What you'll do

 - Provide 3rd-level routing & switching support for NATO CIS (permanent and deployable)

 - Diagnose and resolve complex faults, locally and remotely

 - Run maintenance, backups and restores; keep documentation current

 - Own incident, change and release management to NATO process

 - Produce monthly service-performance and post-incident/RCA reports

 - Take part in governance and continuous service improvement
