Ideal Candidate

The strongest candidate will be a hands-on network/systems infrastructure engineer who understands how enterprise devices and servers are discovered, accessed, authenticated, and scanned.

This is not strictly a ServiceNow administrator role. The priority is deep infrastructure knowledge and the ability to troubleshoot why ServiceNow or another discovery platform cannot successfully reach, authenticate to, or collect information from a device or server.

Candidates with strong network engineering or systems administration backgrounds, combined with PowerShell/Python scripting and exposure to CMDB/discovery technologies, should be particularly well aligned., * Network infrastructure: 5 years (Preferred)
