A client of Insight Global is seeking a System Administrator to sit onsite in West Mifflin, PA or Schenectady, NY in support of a large government contract. This role is ideal for someone who enjoys automating processes, improving system efficiency, and leveraging scripting to support IT operations at scale. This position involves daily IT system monitoring, operational support, and administration of Group Policy, with a strong emphasis on developing and maintaining scripts (e.g., PowerShell, Python, or Bash) to automate routine tasks, streamline system administration, and enforce consistent configurations. The candidate will apply security and system configurations in alignment with government and vendor requirements, including scripting solutions for system hardening, patching, and compliance validation. Responsibilities include creating, deploying, and maintaining computer images for physical and virtual environments, as well as building scripted solutions for image deployment and system provisioning. The individual will also work with the user community to troubleshoot issues, leveraging automation where possible to resolve recurring problems and improve response times.
The role supports enterprise applications such as Exchange, SharePoint, O365, and Tenable, with opportunities to automate administrative tasks, reporting, and system health checks. Additional responsibilities include supporting virtual server and desktop infrastructure (Citrix/VMware), managing endpoints and thin clients, and developing scripts for asset management, software packaging, and deployment processes.
This position also involves reviewing hardware and software for IT-supported networks, supporting client/server infrastructure, and utilizing security tools across the environment—while continuously identifying opportunities to replace manual processes with scalable, script-driven solutions.
