Technology Engineer Jobs in San Antonio, TX (NOW HIRING)

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.

• 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
