OT Systems Engineer (Supercomputer Infrastructure) at xAI · LumiJobs

Responsibilities

SpaceXAI is looking for a highly skilled and versatile OT (Operational Technology) Systems Engineer to implement and support the backend infrastructure for next-generation controls and industrial software platforms critical to our hyperscale AI supercomputer campuses and co-located power generation. This role sits with the Supercomputer Physical Infrastructure team and supports dedicated controls, facilities, and power organizations while leveraging adjacent IT expertise, tooling, and technologies. You will balance sustainment of live cooling, power, and facility control systems with modernization and continuous improvement. The ideal candidate thrives in high-stakes, 24/7 environments, brings a strong sense of urgency balanced with operational excellence, and combines deep OT expertise with IT technologies such as virtualization, VDI, GitOps, network-level redundancy, and edge compute to create streamlined and secure ICS environments for ultra-dense AI compute.
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.
