SpaceXAI is seeking a highly skilled OT Systems Engineer to design, deploy, and maintain next‑generation operational technology environments for its hyperscale AI supercomputer campuses. The role focuses on cooling, power, and facility control systems, integrating IT and OT technologies to ensure secure, reliable, and scalable infrastructure across Memphis and Southaven sites.

Requirements

Skills

  • 3+ years of experience in OT systems engineering or industrial control systems administration.
  • Hands-on experience with multiple industry-standard controls software platforms and tools.
  • Significant experience designing, deploying, supporting, and troubleshooting OT environments in high-reliability settings.
  • Experience supporting real-time systems, industrial control networks, or OT environments in data centers, power generation, semiconductor, energy, or similar high-reliability industries.
  • Direct experience with BMS, EPMS, SCADA, and PLC systems serving large cooling plants, medium-voltage distribution, and mission-critical facilities.
  • Experience designing architectures that incorporate hyperconverged, rugged industrial edge, and distributed compute technologies.
  • Working knowledge of industrial protocols (BACnet, Modbus, OPC UA, MQTT, Ethernet/IP, DNP3), controls networks, and OT cybersecurity best practices.
  • Proficiency in scripting (Bash / PowerShell / Python) and automation frameworks (Puppet, Terraform, Ansible, etc.).
  • Experience with configuration management, provisioning, infrastructure as code, and DevOps concepts/tools.
  • Familiarity with Active Directory, multi-platform authentication, and identity environments in OT contexts.
  • System administration experience managing Windows and Linux servers, rudimentary database administration, and storage/backup.
  • Network administration experience and understanding of the OSI model, especially Layer 1/2/3 considerations as they apply to industrial and facility networks (segmentation, VRFs, MDFs/IDFs).
  • Excellent communication skills with the ability to work with internal teams, vendors, and management in both formal and informal settings.
  • Willingness to participate in an after-hours on-call rotation and work extended hours or weekends as necessary to support live campus operations.
  • Willingness to travel (up to 20%) between Memphis, Southaven, and other sites as the campus expands.
  • Ability to lift 30 lbs.
  • Ability to work at heights and in plant / data hall environments.
  • Ability to drive (active valid driver’s license).
  • Ability to work onsite in the Memphis, TN / Southaven, MS area.

Responsibilities

  • Design, deploy, and augment next-generation OT environments that support cooling plants, electrical distribution, liquid-cooling loops (CDUs / facility water), on-site generation, BESS, and data hall systems across the Memphis / Southaven campus and future sites.
  • Install, configure, maintain, and support industry-standard controls software platforms (BMS, EPMS, SCADA, PLC) as well as internally developed HMIs.
  • Integrate established and emergent IT technologies to simplify management, improve security, and create scalable, highly available plant and facility environments.
  • Deploy and maintain development, test, and staging environments to enable controlled, systematic change introduction on live critical systems.
  • Provide direct support during cluster bring-up, capacity expansions, commissioning, and production training campaigns.
  • Perform systems/software upgrades and maintenance between critical operations (including evenings and weekends as needed).
  • Proactively monitor services and respond rapidly to incidents to maintain high availability and performance of power, cooling, and environmental control.
  • Leverage automation tools and contribute to infrastructure-as-code and broader DevOps initiatives with a focus on ICs / OT environments.
  • Work with controls, mechanical, and electrical engineers to iterate on simulation and emulation environments to enhance test coverage and change control.
  • Write and maintain standards, architectures, best practices, and documentation (system overviews, design drawings, operational procedures), with emphasis on highly reliable and secure industrial environments, especially at IT/OT and data-hall boundaries.
  • Collaborate with cross-functional teams (IT, security, controls, facilities operations, construction, and power) as well as vendors and integrators to design robust OT architectures and resolve technical issues.
  • Ensure OT systems are configured and maintained in compliance with industry and cybersecurity standards (e.g., Purdue Model, IEC 62443).
