Oneida Professional Services is seeking a Systems Administrator to support the Defense Information School (DINFOS) Technology & Logistics Support Services contract at Fort Meade, Maryland. This position is responsible for administering, maintaining, and securing enterprise server environments and supporting the reliable operation of DINFOS information systems.

We are seeking a technically skilled and motivated Tier 2 Desktop Support Specialist to provide advanced workstation troubleshooting, application support, and technical escalation services within a Department of War (DoW) environment.

The ideal candidate is an analytical problem-solver with strong technical aptitude, a passion for technology, and a demonstrated commitment to continuous learning. This is a full-time, on-site position focused on Windows 11 workstations rather than frontline customer support or server administration.

• Diagnose and resolve advanced Windows 11 operating system issues, including performance degradation, application failures, configuration errors, and system instability.
• Perform in-depth technical investigations using Windows Event Viewer, system logs, diagnostic utilities, and other troubleshooting resources to identify root causes.
• Troubleshoot desktop and laptop hardware, peripherals, and workstation-related connectivity or configuration issues.
• Investigate and remediate workstation vulnerabilities, security configuration deficiencies, and compliance-related findings in coordination with infrastructure and cybersecurity teams.
• Provide advanced troubleshooting and support for enterprise applications, including Microsoft Office, Adobe Creative Cloud, and other business-critical software.
• Act as a technical liaison between the Service Desk and Infrastructure/System Administration teams, performing workstation-level troubleshooting, configuration changes, and remediation activities as requested.
• Represent the Service Desk in technical discussions, operational events, and cross-functional initiatives with other departments.
• Identify recurring technical issues, perform root cause analysis, and develop sustainable solutions to improve workstation reliability and reduce repeated incidents.
• Develop, maintain, and improve Standard Operating Procedures (SOPs), knowledge-base articles, and technical documentation to support consistent and effective troubleshooting.
• Proactively identify opportunities to improve escalation workflows, troubleshooting procedures, and overall IT support operations.

Required Qualifications:

• Strong working      knowledge of Microsoft Windows 11 operating systems, including      configuration, troubleshooting, maintenance, and system diagnostics.
• Demonstrated ability      to independently investigate and resolve complex technical issues through      analytical thinking, research, and methodical troubleshooting.

• Working knowledge of      desktop and laptop hardware, peripherals, and common workstation-related      troubleshooting techniques.
• Ability to      troubleshoot enterprise applications, interpret error messages and      diagnostic information, and identify underlying causes of application      failures.
• Familiarity with      Microsoft Active Directory concepts, including user accounts, computer      objects, and common domain-related troubleshooting.
• Understanding of      enterprise IT support practices, technical escalation procedures, and      incident management workflows.
• Ability to create      clear and accurate technical documentation, troubleshooting procedures,      and Standard Operating Procedures (SOPs).
• Strong communication      and collaboration skills, including the ability to work effectively with      Service Desk personnel, system administrators, cybersecurity teams, and      organizational leadership.
• Demonstrated technical      curiosity, initiative, adaptability, and a commitment to continuous      learning and professional development.
• Ability to work      full-time on-site within a Department of War facility and satisfy      applicable government access and security requirements.

• Experience      troubleshooting and supporting Adobe Creative Cloud applications,      including installation, licensing, configuration, and application-specific      issues.
• Experience supporting      Microsoft Office applications and other commonly used enterprise      productivity software.
• Familiarity with      PowerShell scripting, basic automation concepts, or command-line      troubleshooting tools.
• Experience      investigating and remediating workstation vulnerabilities, security      findings, or endpoint configuration issues.
• Experience developing      technical documentation, improving troubleshooting procedures, or      identifying opportunities for operational process improvement.
• Demonstrated      independent technical learning, hands-on experimentation, or self-directed      technical projects that reflect a strong interest in IT and continued      skill development.
