Systems Administrator

As an early member of Antares IT operations function, you will support the infrastructure required for software, engineering, manufacturing, and business teams to move quickly and securely. You will work hands-on across endpoints, identity and access management, network infrastructure, collaboration tools, conference rooms, cloud services, and internal applications while helping maintain the reliability and security expected in a regulated, government-facing environment.

The ideal candidate is a technically versatile junior systems administrator who can troubleshoot quickly, document clearly, and balance operational rigor with speed. This person will be comfortable supporting both technical and non-technical users, working onsite with engineering and manufacturing teams, and improving repeatable processes as Antares scales.

• Provision, configure, and manage user accounts, endpoints, groups, licenses, and access controls across enterprise systems.
• Administer and maintain the Microsoft 365 environment, including Entra ID, Intune, Defender, Exchange, Teams, SharePoint, and related admin workflows.
• Deploy, configure, maintain, patch, and decommission Windows and macOS endpoints; support Linux systems and engineering workstations as needed.
• Support day-to-day IT operations by troubleshooting workstations, peripherals, servers, identity issues, VPN connectivity, conference rooms, and network incidents.
• Maintain and troubleshoot network infrastructure, including LAN/WAN, WiFi, VPN, DNS, DHCP, routing, VLANs, switching, cabling, and port-security/NAC concepts.
• Configure and support collaboration and conference-room technologies, including Microsoft Teams, Zoom, displays, cameras, audio systems, and room scheduling equipment.
• Manage endpoint lifecycle processes including imaging, enrollment, device preparation, patching, updates, inventory, asset tracking, and secure disposal.
• Administer endpoint protection, security certificates, encryption, device compliance policies, and patch management processes.
• Deploy, maintain, and secure in-house and cloud applications used by engineering, operations, manufacturing, and business teams.
• Deploy and maintain PSA/RMM, ticketing, monitoring, automation, and remote-management tools to improve visibility and response times.
• Document IT procedures, configurations, access decisions, support runbooks, and recurring workflows in a way that supports compliance and audit readiness.
• Assist with regulatory and customer compliance efforts, including logging, reporting, evidence collection, access reviews, and audit preparation.
• Support IT operations in manufacturing, lab, shop-floor, or regulated environments, partnering with engineering, facilities, security, and operations as needed.

Basic Qualifications:

• 2+ years of hands-on IT support, systems administration, endpoint administration, or equivalent technical experience.
• Working knowledge of Microsoft 365 administration, including Entra ID/Azure AD, Intune, Defender, device enrollment, user lifecycle management, and access controls.

Preferred Skills and Experience:

• Experience supporting and troubleshooting Windows and macOS endpoints in a business environment.
• Solid networking fundamentals, including TCP/IP, DNS, DHCP, routing, VLANs, VPN, WiFi, switching, and basic firewall concepts.
• Proficiency with PowerShell or similar scripting/automation concepts, plus comfort using command-line diagnostic tools.
