Security Engineer

The Challenge:

Everyone knows security needs to be "baked in" to a system architecture, but you actually know how to bake it in. You can identify and implement ways to harden systems and reduce their attack surface. What if you could use your cyber engineering skills to lead the design and building of secure systems for the Department of Defense? We're looking for an engineer who can create solutions that will stand up to even the most advanced cyber threats.

As a lead security engineer on our project, you'll design and support the implementation of new security tools and technologies. You'll coordinate work with the client to identify the right mix of tools and techniques to translate your customer's IT needs and future goals into a plan that will enable secure and effective solutions. You'll document all configuration changes as well as software and hardware versions using the appropriate office documentation processes. We need to come up with the best solution, so you'll advise on new techniques, break free from the legacy model, and go where the industry is going. You'll lead the team through a critical approach to network design, providing alternatives and customizing solutions to maintain a balance of security and mission needs.

Empower change with us.
