WebCDR.com is a privately-held telecom software company providing
operations support services (OSS) to the international wholesale
telecom industry. We are looking for a senior linux systems
administrator with strong Perl skills for a full-time position in San

We have 90 servers running OpenSUSE Linux. We have OpenSUSE Linux

automatically built and configured using our custom configuration

our in-house tools are written in Perl, the rest are mostly bash

always fighting fires, and we like to hire excellent people so we can
keep it that way.
