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.

- 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%)
The listed responsibilities are not exhaustive and additional responsibilities may be assigned based on the evolving needs of the organization. We are seeking a dynamic individual who is able to adapt and take on new responsibilities as they arise.
Minimum Experience and Qualifications- 3+ years in an IT operations, systems administration, or infrastructure role
- Hands-on experience racking and configuring servers and network switches in a lab or data center environment
- Experience with virtualization platforms on IT-managed infrastructure (Proxmox, ESXi, or similar)
- Demonstrated homelab or lab environment experience, comfortable standing up and troubleshooting infrastructure from scratch
- Familiarity with structured cabling, patch panel termination, and physical infrastructure documentation
- Experience with layer 2/3 networking concepts (VLANs, switching, routing)
- Experience with change management processes and IT documentation practices
- Experience with helpdesk or trouble ticketing systems
- Familiarity with macOS endpoint management and MDM solutions (Jamf preferred)
- Experience with Google Admin Console or similar directory/identity management tools
- US citizenship required; must be eligible for CUI access
