What if you could use those skills to improve the technology supporting warfighters? We're looking for a system administrator who is comfortable installing, configuring, and maintaining Red Hat Enterprise Linux (RHEL) systems across physical, virtual, and cloud-based environments. In addition, you're comfortable applying systems updates and patches, and conducting various scans to maintain cyber compliance. This combination of skill and action will help us build, field, and sustain next-generation software solutions for the client and deploy cybersecurity solutions that can be leveraged across the Department of War. As a system administrator and cyber analyst on our project, you'll install, configure, and manage RHEL and Windows operating systems to ensure that they meet client needs while also being compliant with Risk Management Framework (RMF). You will assess and manage system performance, while also authoring documentation to capture configuration changes, procedure updates, and troubleshooting guides as needed. As a client-facing asset, you provide direct communications to the client to articulate technical challenges, risks, and solution options that are executable and affordable. Your system administrator expertise will be vital as you identify problem areas and opportunities for improvement in a mission-critical network. You'll help your team better understand the network by turning metrics into information and explaining their meaning. This is an opportunity to apply and sharpen your systems administration and cybersecurity skillsets while also becoming a critical asset that is responsible for both maintaining and upgrading system networks. We focus on growing as a team, so you'll share your expertise through leadership as you help the team work through challenges and develop new methodologies. As a system administration leader, you'll identify new opportunities to modernize the network, so your clients achieve their goals. Work with us and resolve daily challenges as we improve warfighter lethality, awareness, and decision-making across the battle space.
