Systems Administrator

About the Company

General Matter enriches uranium.

We are designing, building, and operating the world’s lowest-cost enrichment services, here in the US.  

In the process, we are restoring America’s ability to produce nuclear fuel to power AI, advanced manufacturing and critical industries our country relies on to remain competitive. 

Fuel drives the cost of advanced reactor electricity production, and enrichment drives the cost of the fuel that advanced reactors consume.  Reliable, low-cost enrichment is the catalyst for the nuclear Renaissance now under way.

Our mission is to make nuclear not only the cleanest and safest source of baseload power, but also the most affordable.  We believe abundant nuclear energy will lead to a post-scarcity society. 

We were incubated inside Founders Fund, like Anduril and Palantir before us, and are backed by over a dozen of the world's top venture capital firms.  

Our lean, world-class team of engineers and operators is applying a first-principles approach to solving the problem of nuclear fuel production.  

We are a mission-driven company with a culture of urgency, accountability, and transparency. 

Help us build a high-energy society by making the cleanest, safest form of baseload energy the most affordable. 

About This Role

We’re looking for a Systems Administrator to support our growing team in a fast-paced, engineering-driven environment. This is a hands-on, broad-scope role that spans both on-prem infrastructure and Microsoft 365 / Azure environments, ensuring our systems are secure, reliable, and built for scale. 

You’ll work closely with our engineering, IT, and operations teams to support critical business systems and technical workloads — from cloud identity management to high-performance engineering desktops and simulation clusters. This role blends deep technical work with IT Service Management (ITSM) process development, helping build a scalable, high-performing IT foundation. 

Responsibilities:

• Design, deploy, and maintain on-prem infrastructure, including Linux and Windows servers, storage, networking, and virtualization. 
• Administer and optimize Microsoft 365 and Azure services (Azure AD, Intune, Exchange Online, SharePoint, Teams). 
• Manage identity, access, endpoint compliance, and system security across hybrid environments. 
• Implement and maintain monitoring and alerting systems across on-prem and cloud platforms (e.g., Datadog, Grafana, Prometheus, Splunk, Azure Monitor). 
• Support engineering and simulation applications (CAD, CAM, CFD) on both Windows and Linux platforms — ensuring uptime, performance, and license management. 
• Automate operational workflows and provisioning using PowerShell, Python, or similar scripting tools. 
• Contribute to ITSM initiatives, including incident, change, and configuration management processes. 
• Collaborate cross-functionally to deploy and maintain critical infrastructure and applications. 
• Participate in helpdesk and escalation support — we operate as an all-hands-on-deck team. 
• Maintain thorough documentation, SOPs, and change records to support reliability and compliance. 

Basic Qualifications:

• 5+ years of experience as a System Administrator or equivalent technical role. 
• Hands-on experience with both Linux and Windows servers in hybrid (on-prem + cloud) environments. 
• Strong background managing on-prem infrastructure — servers, virtualization, storage, and networking. 
• Deep expertise in Microsoft 365, Azure AD, Intune, and Exchange Online. 
• Proficiency in identity management, endpoint security, and monitoring and alerting systems. 
• Solid troubleshooting and problem-solving skills across diverse systems. 
• Excellent communication and documentation skills. 
• Interest in structured operations and ITSM best practices. 

Preferred Skills and Experience:

• Experience in aerospace, defense, or other regulated technical environments. 
• Familiarity with GCC High or FedRAMP environments. 
• Experience supporting engineering software such as SolidWorks, CATIA, ANSYS, or Siemens NX. 
• Knowledge of VMware, Hyper-V, and enterprise storage or networking design. 
• Experience with automation/scripting (PowerShell, Python, Bash). 
• Background in ITIL, service delivery, or process implementation. 

Additional Requirements:

• Ability to work extended hours and weekends as necessary.
• Ability to come into our office every day. This role is 100% on site and in person.
• Currently a US Citizen with capability to obtain and maintain a US Q clearance.
