T12 Technologies is seeking a skilled and service-driven System Administrator to manage and maintain our on-premises and cloud systems on-site at our Waldorf, Maryland office. This is a fully on-site role supporting an on-premises-inclusive environment—physical workstations and office IT, an on-premises Windows Server and Active Directory footprint, and the company network—alongside cloud workloads in Microsoft 365, Microsoft Azure, and Amazon Web Services (AWS), serving diverse federal, state, and healthcare clients.
This is a hands-on, player-coach role: roughly 60% systems and cloud administration and 40% Tier 1–2 end-user support. You’ll keep mission-critical systems available, secure, and compliant while serving as a trusted technical resource to internal teams and client stakeholders.
Work Environment & Schedule- On-site: This is a fully on-site position based at T12’s Waldorf, Maryland office. It is not a remote or hybrid role; daily in-office presence is required to support physical office IT, end users, and on-premises infrastructure.
- Schedule: Full-time, Monday through Friday during standard business hours.
- On-call / after-hours: Occasional after-hours, weekend, or on-call work is required to perform maintenance windows and meet federal and healthcare service-level agreements (SLAs).
- Environment: An on-premises-inclusive environment that includes on-premises Active Directory (with Group Policy), a Windows Server fleet, physical endpoints and peripherals, the office LAN/Wi-Fi, and hybrid telephony—administered alongside Microsoft 365, Azure, and AWS cloud workloads.
- AWS Cloud Administration: Provision, monitor, and maintain AWS services (EC2, S3, IAM, VPC, RDS, Cloud Watch), including patching, backups, cost optimization, and security configuration.
- Microsoft Environment Management: Administer Microsoft 365 (Exchange Online, Teams, SharePoint, One Drive), Microsoft Entra (Azure AD), Conditional Access, MFA, and Active Directory (users, groups, GPOs).
- Endpoint & Device Management: Manage device compliance, configuration, and application deployment through Microsoft Intune; support onboarding and offboarding of users and hardware.
- System Monitoring & Availability: Monitor system health, capacity, and performance; respond to alerts and resolve incidents to meet SLA commitments.
- Patching, Backup & Recovery: Perform routine patching, updates, backups, and disaster recovery testing across cloud and on-premises systems.
- Security & Compliance: Implement and enforce access controls, configuration baselines, and security hardening aligned with frameworks such as NIST 800-171, HIPAA, and CIS (depending on client vertical).
- Automation & Scripting: Build and maintain Power Shell and/or Bash scripts to automate recurring administrative tasks and reporting.
- Documentation & Knowledge Sharing: Maintain system diagrams, SOPs, runbooks, and asset inventories; contribute to internal knowledge bases.
In a small-company environment, the System Administrator is often the first and only point of contact for day-to-day technology issues. This role provides hands-on Tier 1–2 support across phones, computers, and network connectivity, including:
- First-Line Troubleshooting: Serve as the primary point of contact for end-user issues; triage and resolve requests received by phone, email, ticketing system, and in person.
- Desktop & Hardware Support: Diagnose and resolve issues with desktops, laptops, printers, peripherals, and mobile devices; image, configure, and deploy new equipment.
- Telephony & Communications: Troubleshoot phone systems (VoIP/softphone), conferencing, and Microsoft Teams calling—including handset setup, call routing, and voicemail issues.
- Network Connectivity: Resolve local network problems such as Wi-Fi, LAN, VPN, DNS/DHCP, and router/switch/ISP connectivity; coordinate with carriers or vendors to elevate as needed.
- Account & Access Support: Handle password resets, account lockouts, mailbox and shared-drive permissions, and software installation and licensing requests.
