Bridge Defense seeks a Linux Systems Administrator to support the N6 IT Fleet Weather Center San Diego (FWCSD) department as it relates to system administration requirements and compliance. FWC-SD provides an asymmetric war fighting advantage to Fleet Forces through application of METOC forecasts, warnings, and recommendations for Fleet Commanders afloat and facilities ashore in support of asset protection responsibilities and risk management decisions.
