EMPLOYER IS A CONTRACTOR FOR THE U.S. GOVERNMENT. THIS POSITION WILL REQUIRE U.S. CITIZENSHIP.

Role Description: 

We are seeking an IT Engineer to join our team, based primarily out of our San Antonio, TX office. This role is first and foremost a hardware role, the primary owner of physical infrastructure at Defense Unicorns' San Antonio location, responsible for racking servers, configuring switching and network gear, and maintaining a growing lab environment that supports active defense programs. When not heads-down on hardware, this person is a contributor to day-to-day IT operations, handling helpdesk tickets, endpoint support, and IT projects alongside the broader IT OPS team. The ideal candidate thrives in a hands-on lab environment, has real experience standing up physical infrastructure, and can context-switch into IT OPS work without losing momentum. This is an onsite role; physical presence is the job.

Hardware & Infrastructure (~70%)

• Install, configure, and maintain servers, rack-mount switches, and associated network infrastructure in the San Antonio office and lab environments
• Stand up and maintain virtualization environments on IT-owned bare-metal hardware
• Lead rack layout, cable management, patch panel termination, and physical infrastructure documentation
• Support UPS and PDU installation, configuration, and monitoring
• Configure and maintain network infrastructure including switches, access points, and security appliances
• Lead hardware procurement coordination, maintain physical and digital asset inventory, and support engineering and delivery teams with hardware staging needs
• Assist with edge and lab hardware as needed, including mini PCs, single-board computers, and portable networking gear
• Support physical security infrastructure as needed, including access control and related CMMC-adjacent hardware considerations

IT Operations (~30%)

• Provide Tier 1 and Tier 2 helpdesk support, triaging and resolving tickets or escalating as appropriate
• Administer MDM (Jamf) for device enrollment, policy enforcement, and compliance reporting
• Support endpoint hardware management (primarily macOS) alongside other IT team members, including imaging, configuration, deployment, and decommission
• Support user onboarding and offboarding workflows including access provisioning and equipment movement
• Manage access through Google Admin Console and related identity tools
• Collaborate with third-party vendors and internal stakeholders on SaaS tool rollouts, troubleshooting, and updates
• Contribute to IT projects, process improvements, and compliance initiatives aligned with NIST SP 800-171 and CMMC

Travel Expectations/Requirements: Primarily onsite in San Antonio; occasional travel to other Defense Unicorns locations (~20%)
