The CSfC Engineer serves as a technical subject matter expert for solutions utilizing commercial technologies in accordance with NSA Commercial Solutions for Classified (CSfC) requirements, Capability Packages, and applicable DoD cybersecurity standards. This position requires extensive experience with secure network architecture, encryption, VPN technologies, firewalls, routing and switching, endpoint security, PKI, certificates, mobile and remote access solutions, and classified network environments. The Engineer works closely with cybersecurity, network engineering, systems engineering, Information System Security Managers/Officers (ISSM/ISSO), and government stakeholders to develop secure, compliant, and operationally effective CSfC solutions. The CSfC capability is known as Virtual Secure - Remote (ViSR) and supports remote SIPRNet access for up to 2,000 concurrent users initially but could be scalable up to 15,000 concurrent users as the Government continues to onboard users. The successful candidate will lead the Operations and Maintenance activities and provide engineering support to expand the capacity of the Fort Bragg ViSR solution set. The candidate will also provide support to implement the solution architecture in other NETCOM areas of operation., * Design, engineer, implement, configure, and sustain NSA CSfC solutions supporting classified DoD communications and information systems. * Develop CSfC architectures in accordance with applicable NSA CSfC Capability Packages (CPs) and approved Components List requirements. * Engineer secure solutions using two independent layers of commercial encryption to protect classified information across untrusted networks. * Design and support CSfC solutions for Mobile Access, Campus WLAN, Multi-Site Connectivity, Data-at-Rest, and other applicable use cases * Evaluate commercial hardware and software products for compliance with CSfC requirements and integration into existing DoD network architectures. * Configure and troubleshoot VPN gateways, IPsec tunnels, firewalls, routers, switches, wireless infrastructure, endpoint devices, and associated security components. * Develop detailed network diagrams, security architectures, data-flow diagrams, interface documentation, bills of materials, configuration baselines, and implementation procedures. * Support CSfC solution registration, authorization, assessment, documentation, and maintenance activities. * Maintain configuration compliance with approved CSfC architectures, Capability Packages, and established security baselines. * Perform technical analysis of new or revised NSA CSfC requirements and determine their impact on deployed solutions. * Support implementation of required software, firmware, certificates, cryptographic algorithms, and security configuration updates. * Perform vulnerability remediation, patching, configuration management, and lifecycle management for CSfC components. * Troubleshoot complex connectivity, encryption, authentication, certificate, routing, firewall, and endpoint issues. * Perform root-cause analysis of CSfC service interruptions and develop corrective actions to restore mission capability. * Develop and execute implementation plans, test plans, rollback procedures, and validation procedures for system changes. * Participate in technical reviews, engineering boards, change-control activities, and configuration-management processes. * Provide Tier III engineering support for CSfC-related incidents and escalated technical issues. * Coordinate with vendors, government engineering organizations, cybersecurity personnel, and other technical stakeholders to resolve interoperability and security issues. * Maintain accurate as-built documentation and configuration records for deployed CSfC solutions. * Perform special projects and other duties as assigned. ## Related Videos - [How Cisco embraced a DevOps culture within its network engineering team](https://www.wearedevelopers.com/videos/99-how-cisco-embraced-a-devops-culture-within-its-network-engineering-team) - [Cyber Sleuth: Finding Hidden Connections in Cyber Data](https://www.wearedevelopers.com/videos/893-cyber-sleuth-finding-hidden-connections-in-cyber-data) - [Docker network without Docker](https://www.wearedevelopers.com/videos/1418-docker-network-without-docker) - [Your Infrastructure Is Not a Playground: AI Agents for Infra Done Right](https://www.wearedevelopers.com/videos/2084-your-infrastructure-is-not-a-playground-ai-agents-for-infra-done-right) - [Computer Vision from the Edge to the Cloud done easy](https://www.wearedevelopers.com/videos/263-computer-vision-from-the-edge-to-the-cloud-done-easy) - [Docker exec without Docker](https://www.wearedevelopers.com/videos/1094-docker-exec-without-docker) ## Related Articles - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [Dev Digest 134 - Where pixels sing?](https://www.wearedevelopers.com/magazine/477-dev-digest-134-where-pixels-sing) - [Highest Paying Tech Companies for Developers](https://www.wearedevelopers.com/magazine/220-highest-paying-tech-companies-for-developers) - [9 Ways to Make Money Hacking](https://www.wearedevelopers.com/magazine/333-9-ways-to-make-money-hacking) - [Events like RSAC Get You CISOs.
