Job description

At PMAT, we work on mission critical systems that directly support the warfighter, designing, building, and securing modern digital capabilities across cloud, data, and software environments. Our teams tackle complex, real-world challenges where delivery matters more than theory, and innovation is driven by curiosity, collaboration, and purpose.
In this role, you'll contribute to Naval Operational Architecture (NOA), working alongside engineers and operators to deliver resilient, forward-leaning solutions in support of national defense.
About the role: PMAT is seeking a motivated and technically capable System Administrator II to support the administration, monitoring, troubleshooting, and sustainment of Windows, Linux, virtualization, network, and tactical computing environments. This mid-level role supports day-to-day system operations, user support, vulnerability remediation, patching, backup and recovery, system documentation, and performance monitoring across enterprise and mission-focused environments. The candidate will work with IT, cybersecurity, engineering, data, and operational teams to help maintain secure, reliable, and mission-ready systems. The role requires strong problem-solving skills, collaborative communication, and the ability to support both traditional IT infrastructure and tactical systems in a fast-moving technical environment.
Responsibilities:
  • Administer and maintain Windows, Linux, ESXi, network, and tactical computing environments by supporting installation, configuration, updates, monitoring, and troubleshooting activities.
  • Support system security and compliance activities by assisting with patching, vulnerability remediation, security hardening, access control, cybersecurity guidelines, and audit-ready documentation.
  • Monitor server, network, and system performance by identifying issues, troubleshooting problems, supporting optimization efforts, and escalating complex technical risks as needed.
  • Support backup and recovery procedures by helping maintain data protection processes, validating system availability, and documenting recovery actions.
  • Provide end-user and technical team support by resolving system-related issues, answering technical questions, documenting troubleshooting steps, and coordinating follow-up actions.
  • Assist with network infrastructure support by helping maintain routers, firewalls, VPNs, and related network devices in coordination with senior administrators and engineering teams.
  • Support tactical systems and data environments by assisting with troubleshooting, tactical data pipeline monitoring, edge server operations, embedded GPU environments, and containerized workloads.
  • Maintain system documentation, configuration records, software inventories, license tracking, hardware tracking, and End-of-Life planning inputs to support infrastructure visibility and sustainment.

About Us: PMAT is an innovative small business founded with a passion for developing forward-leaning solutions from exceptional people that increase the mission's capability. We focus on designing and building impactful digital solutions that utilize modern cloud, data, and software concepts. Our passion is working on complex and progressive challenges such as edge platform computing, containerizing legacy platforms, distributed data platforms, or heterogeneous data analysis.
We recruit, retain, and foster a team motivated to pursue passions, investigate new ways of doing things, and embody an innovative and entrepreneurial spirit. We believe in being curious about every element of a problem and experiment relentlessly. We foster continuous learning in an environment that encourages positive collaboration and expands our capabilities. We tap into collective intelligence, acknowledging that the most brilliant people may not be in the room. Above all else, we believe that delivering and demonstrating is more potent than a sheet of paper. We are passionate about mission-centric design and delivering effective capabilities to and for the warfighter.
Whether you're an experienced engineer or just beginning your career, you'll work alongside experts who are committed to solving mission-critical problems. If you're passionate about using your skills to make a real difference, apply today and become part of a team that's shaping the future of defense technology!
Required Skills and Experience:
  • Experience working as a system administrator, IT specialist, network administrator, data engineer, database administrator, software engineer, machine learning engineer, geospatial engineer, or related technical role.
  • Intermediate experience using the Linux command line to support system administration, troubleshooting, file management, process management, and technical operations.
  • Experience supporting Windows and Linux operating systems, system configuration, user support, patching, monitoring, and troubleshooting activities.
  • Understanding of networking concepts and protocols such as TCP/IP, DNS, DHCP, VPNs, ports, routing, and firewall concepts.
  • Experience supporting cybersecurity, access control, vulnerability remediation, system hardening, patching, or secure configuration activities.
  • Strong problem-solving, analytical, time management, and multitasking skills in a dynamic technical environment.
  • Excellent written and verbal communication skills with the ability to work effectively with IT, cyber, engineering, data, and operational stakeholders.

Preferred Skills and Experience:
  • Familiarity with virtualization and containerization technologies such as VMware, Docker, Kubernetes, or related platforms.
  • Familiarity with edge servers, embedded GPUs, tactical computing hardware, Jetson Nano, DGX Spark, or similar mission hardware.
  • Experience troubleshooting tactical systems or supporting tactical data pipelines, including deployment, monitoring, sustainment, or improvement activities.
  • Familiarity with security assessment tools, vulnerability scanning tools, CMMC compliance concepts, DISA STIG guidance, operating system hardening, and network hardening.
  • Familiarity with shell scripting, automation, or configuration tools such as Bash, Python, Ansible, PowerShell, or similar technologies.
  • Familiarity with cloud and enterprise services such as Amazon Web Services, GCC High, Microsoft 365, Azure, Intune, or related environments.
  • Previous experience working with government agencies, Navy organizations, military users, or Department of War mission environments.
  • Passion for staying current with advancements in tactical data architecture, system administration, cybersecurity, and mission infrastructure technologies.
