Apptronik is a human-centered robotics company developing AI-powered robots to support humanity in every facet of life. Our flagship humanoid robot, Apollo, is built to collaborate thoughtfully with people, starting with critical industries such as manufacturing and logistics, with future applications in healthcare, the home, and beyond. We operate at the cutting edge of embodied AI, applying our expertise across the full robotics stack to solve some of society's most important problems. You will join a team dedicated to bringing Apollo to market at scale, tackling the complex challenges like safety, commercialization, and mass production to change the world for the better.
JOB SUMMARY
As Apptronik continues to scale its humanoid robotics platform, we are seeking an experienced IT Systems Administrator to own the day-to-day operation of our on-premise Linux infrastructure in Austin, TX. This role is responsible for the health, security, and reliability of the physical servers, storage, networking, and compute environments that engineering teams rely on to design, simulate, train, and validate our robots. You will administer Linux fleets at scale, harden and automate the environment with configuration management and scripting, and partner closely with robotics, ML, and infrastructure engineering teams to keep our build, lab, and data center systems running. The ideal candidate brings deep hands-on Linux expertise, a strong operational mindset, and the ability to balance reliability, security, and velocity in a fast-moving robotics R&D environment.
ESSENTIAL DUTIES AND RESPONSIBILITIES
- Administer and maintain a fleet of on-premise Linux servers (Ubuntu, RHEL/Rocky/Alma, Debian) supporting engineering, simulation, training, and lab workloads
- Own server lifecycle management end-to-end: racking, provisioning, imaging, patching, decommissioning, and hardware refresh planning
- Operate and tune on-prem virtualization and container platforms (VMware vSphere, Proxmox, KVM/libvirt, and Docker/Kubernetes on bare metal) for internal workloads
- Design, deploy, and maintain on-premise networking — switches, VLANs, routing, DNS, DHCP, NTP, and firewall rules — in partnership with the network team
- Manage on-prem storage systems including NFS, SMB/CIFS, iSCSI, and SAN/NAS arrays, along with the associated snapshot, replication, and backup strategies
- Implement configuration management and infrastructure-as-code using Ansible (preferred), Puppet, Chef, or Salt to ensure consistent, auditable system state across the fleet
- Operate monitoring, logging, and alerting stacks (Prometheus, Grafana, Loki/ELK, Zabbix, or Nagios) and respond to incidents with strong root-cause analysis
- Harden Linux systems and apply security best practices: least-privilege access, SSH key management, SELinux/AppArmor, kernel and package patching, CIS benchmarks
- Administer identity and access for on-prem systems via LDAP, FreeIPA, Kerberos, SSSD, and integration with the corporate identity provider
- Author and maintain automation scripts (Bash, Python) for provisioning, reporting, log analysis, and routine operational tasks
- Plan, test, and document backup and disaster recovery procedures for critical on-prem services; participate in regular restore drills
- Maintain accurate documentation, runbooks, and architecture diagrams for all administered systems; participate in an on-call rotation for production-impacting issues
SKILLS AND REQUIREMENTS
- 4+ years of hands-on Linux systems administration experience in production environments, with primary expertise on Ubuntu and/or RHEL family distributions
- Strong working knowledge of on-premise infrastructure: racking and cabling, BIOS/firmware, IPMI/iDRAC/iLO, PXE boot, and hardware troubleshooting
- Solid experience with on-prem virtualization platforms such as VMware vSphere/ESXi, Proxmox, or KVM/libvirt
- Proficient with configuration management tooling (Ansible preferred; Puppet, Chef, or Salt acceptable) and comfortable applying it to a non-trivial fleet
- Deep familiarity with Linux networking and core network services: DNS (BIND/Unbound), DHCP, NTP/Chrony, TCP/IP, VLANs, routing, and firewalling with iptables/nftables/firewalld
- Experience administering on-prem storage and filesystems: NFS, SMB/CIFS, LVM, ZFS or ext4/XFS, RAID, and SAN/NAS arrays
- Strong scripting skills in Bash and Python for automation, monitoring, and operational tooling
- Working knowledge of Linux security fundamentals: SSH hardening, sudo policy, SELinux/AppArmor, file integrity monitoring, vulnerability and patch management
- Experience operating monitoring and observability stacks (Prometheus, Grafana, Zabbix, Nagios, ELK/Loki) and using them to drive availability and capacity decisions
- Familiarity with backup and DR tooling for on-prem environments (e.g., Bacula, BorgBackup, Veeam, rsync-based pipelines, or commercial equivalents)
- Excellent troubleshooting and incident-response skills, with the discipline to write up clear post-incident analyses
- Strong written and verbal communication; able to work cross-functionally with robotics, ML, and infrastructure engineering teams
NICE TO HAVE
- Experience supporting compute clusters, GPU fleets, or build farms for ML, simulation, or CI workloads
- Hands-on experience with Kubernetes on bare metal (kubeadm, k3s, RKE2, or similar)
- Exposure to robotics, hardware engineering, or manufacturing IT environments

Search System Administrator Jobs in TexasSystem Administrator Jobs in Texas: Frequently Asked Questions
Which companies sponsor visas for system administrators in Texas?
Large employers with significant Texas footprints, including Dell Technologies, AT&T, IBM, Amazon Web Services, and Hewlett Packard Enterprise, have a documented history of sponsoring H-1B visas for system administrator roles. Healthcare systems like HCA Healthcare and energy companies such as ExxonMobil and Chevron also appear in Department of Labor disclosure data as sponsors for IT infrastructure positions in Texas.
Which visa types are most common for system administrator roles in Texas?
The H-1B is the most common visa category for system administrators in Texas, provided the role meets the specialty occupation standard, meaning a bachelor's degree in computer science, information systems, or a closely related field is typically required. L-1B visas are another pathway for intracompany transferees with specialized knowledge of employer systems. TN visa status is also used by Canadian and Mexican nationals in qualifying IT roles.
Which cities in Texas have the most system administrator sponsorship jobs?
Austin leads Texas for sysadmin sponsorship activity, anchored by its dense concentration of tech companies and cloud infrastructure teams. Dallas-Fort Worth is close behind, with major corporate headquarters and managed service providers driving consistent demand. Houston adds volume through its energy sector IT operations and large healthcare networks. San Antonio also sees steady hiring tied to cybersecurity and military-adjacent contractors.
How to find system administrator visa sponsorship jobs in Texas?
Migrate Mate filters job listings specifically to roles where employers are open to visa sponsorship, making it straightforward to search system administrator positions in Texas without sorting through unsponsored listings. You can filter by city, narrowing results to Austin, Dallas, Houston, or San Antonio depending on where you want to work. Migrate Mate pulls from employers with verified sponsorship activity, which is particularly useful for sysadmin roles where sponsorship eligibility varies by team and employer size.
Are there any Texas-specific factors that affect system administrator visa sponsorship?
Texas has no state income tax, which affects prevailing wage calculations slightly compared to higher-tax states, though Department of Labor wage requirements still apply based on the specific metro area. The state's large university system, including UT Austin, Texas A&M, and UT Dallas, produces a pipeline of international graduates on OPT who are commonly hired for sysadmin roles before employers initiate H-1B sponsorship. Defense-adjacent roles in San Antonio may involve security clearance requirements that can complicate sponsorship for some nationalities.
What is the prevailing wage for sponsored system administrator jobs in Texas?
U.S. employers sponsoring a visa must pay at least the prevailing wage, which is what workers in the same role, area, and experience level typically earn. The Department of Labor sets this rate to make sure companies aren't hiring foreign workers simply because they'd accept lower pay than a U.S. worker. It varies by job title, location, and experience. You can look up current prevailing wage rates for any occupation and location using the OFLC Wage Search page.
