Come work for a finalist for Baltimore's Best Places to work for the past 2 years running, and work with some of the most amazing peers in the industry while earning competitive compensation with great benefits!

This opening is for a Senior Network Security Engineer in the DC/NoVA Metro Area to perform project-based consulting with various customers to design, implement, and support Cisco-based networks.

The first project you will undertake as a NetCraftsmen is a Network Segmentation project for a Fortune 500 Global Client, where you will analyze existing VLANs/Network Segments to identify zones which require protection, document required traffic flows for nodes within protected zones, develop an Implementation Plan, and deploy necessary access control list (ACL) and intrusion protection system (IPS) updates. Follow on projects will include a firewall review/upgrade and an 802.1x re-implementation. As part of this project, there will be some out of region travel, which for the first 4 months may be as much as 50% overnight travel (one week on-site, next week home office) for local project execution.
