You will enable engineers and developers to design, build, integrate, and test complex mission systems in both standalone and cloud-based environments. The position requires a hands-on technologist with strong systems administration, networking, and infrastructure expertise, combined with the organizational and operational discipline required for classified environments. You will thrive in a dynamic lab setting, proactively solving problems while managing multiple systems, configurations, and priorities across various classification levels., * Administer and sustain standalone (air-gapped) and cloud-connected systems across multiple classification levels. * Install, configure, and troubleshoot servers, workstations, storage systems, and networking equipment in lab and test environments. * Support integration of complex systems, including embedded hardware, FPGA-based platforms, simulation environments, and test platforms. * Manage system baselines, configurations, and documentation in accordance with security and compliance requirements. * Implement and enforce cybersecurity controls in compliance with Department of Defense policies, including STIGs, RMF, and CMMC frameworks. * Maintain accreditation artifacts and support system Authority to Operate (ATO) processes for classified and mission-critical systems. * Provide hands-on support for system builds, upgrades, patching, and troubleshooting across Linux, Windows, and virtualized environments. * Coordinate closely with engineers, developers, and program teams to ensure infrastructure meets evolving project and mission needs. * Monitor system performance, reliability, and security posture, and proactively identify and resolve issues before they impact operations. * Maintain inventory and lifecycle management of lab assets and infrastructure, ensuring accurate records and timely refresh of equipment. * Support incident response activities, audit readiness efforts, and compliance inspections for classified and secure environments. * Contribute to the design and operation of cloud-based environments, including secure government cloud platforms, to support mission systems. * Apply strong organizational and operational discipline to maintain compliance with security protocols and operational constraints in classified labs., The role is based in a defense-focused integration laboratory that supports mission performance and security systems. You will work with a mix of Linux and Windows systems, virtualized environments using platforms such as VMware and Hyper-V, and secure cloud infrastructures including government cloud solutions. The environment includes servers, workstations, storage arrays, networking equipment, embedded hardware, FPGA-based platforms, and simulation and test systems across multiple classification levels. Many systems operate in standalone and air-gapped configurations, requiring strict adherence to security protocols, documentation standards, and operational discipline. You will routinely implement and maintain cybersecurity controls such as STIGs, SCAP, patching, and hardening, and support accreditation and ATO activities. The work involves close collaboration with engineers, developers, and program teams in a dynamic lab setting where priorities can shift quickly and hands-on problem solving is essential. The position emphasizes compliance, audit readiness, and incident response within a secure, highly regulated environment.
