The Role

Designs, deploys, and supports highly available OT infrastructure for cooling, power, generation, BESS, and data hall systems. Installs and maintains BMS, EPMS, SCADA, PLC, and HMI platforms; manages upgrades, monitoring, incident response, staging environments, automation, and infrastructure-as-code initiatives. Collaborates with controls, electrical, mechanical, IT, security, facilities, construction, and vendors to build secure, reliable ICS environments. Supports commissioning, cluster expansions, training, on-call operations, and documentation across campus sites.

Summary Generated by Built In

SpaceX was founded under the belief that a future where humanity is out exploring the stars is fundamentally more exciting than one where we are not. Today, SpaceX is actively developing the technologies to make this possible, with the ultimate goal of making life multiplanetary and expanding consciousness to the stars.
SpaceXSI is building Super Intelligence to help humanity understand the universe. Our teams are building the full Super Intelligence stack: from our Colossus supercomputers, to Grok models, to our suite of applications, including Grok Bot, Grok Build, Grok Imagine, Grok Voice, and X. We're creating a powerful flywheel where more compute trains better models, better models power more useful products, and what we learn from people using those products shapes what we build next.

OT SYSTEMS ENGINEER, PHYSICAL INFRASTRUCTURE

SpaceXSI is looking for a highly skilled and versatile OT (Operational Technology) Systems Engineer to implement and support the backend infrastructure for our next-generation controls and industrial software platforms for our physical infrastructure. This role is embedded within the mission IT organization to provide support to dedicated controls engineering organizations while leveraging adjacent IT expertise, tooling, and technologies. This role will balance support of legacy controls support systems with modernization and continuous improvement initiatives. The ideal candidate thrives in high stakes settings, 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 solutions to create streamlined and secure ICS environments.

RESPONSIBILITIES:

Design, deploy, and augment next-generation OT environments that support plant and launch systems across multiple sites
Install, configure, maintain, and support industry standard controls software platforms as well as internally developed HMIs
Integrate established and emergent IT technologies to simplify management, improve security, and create scalable plant environments
Deploy and maintain development, test, and staging environments to enable controlled, systematic change introduction
Provide direct support during launch, test, and production 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
Leverage automation tools and contribute to infrastructure-as-code and broader DevOps initiatives with a focus on ICS environments
Work with internal controls engineers to iterate on simulation and emulation environment to enhance test coverage and augment change control processes
Write and maintain standards, architectures, best practices, and documentation (including system overviews, design drawings, and operational procedures), with emphasis on highly reliable and secure industrial environments, especially at data boundaries
Collaborate with cross-functional teams (IT, security, controls, and operations) as well as external customers 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)

BASIC QUALIFICATIONS:

3+ years of experience in OT systems engineering or industrial control systems administration
Experience designing, deploying, supporting, and troubleshooting OT environments in high-reliability settings

PREFERRED SKILLS AND EXPERIENCE:

Hands-on experience with multiple industry standard controls software platforms and tools
Experience supporting real-time systems, industrial control networks, or operational technology (OT) environments in aerospace, defense, energy, or similar high-reliability industries
Experience designing architectures that incorporate hyperconverged, rugged industrial edge, and distributed compute technologies
Working knowledge of industrial protocols, 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 exposure, and storage/backup experience
Network administration experience and understanding of the OSI model, especially Layer 1/2/3 considerations as they apply to industrial and controls networks
Excellent communication skills with the ability to communicate with internal/external customers, vendors, and management in both formal and informal situations

ADDITIONAL REQUIREMENTS:

Willingness to participate in an after-hours on-call rotation and work extended hours or weekends as necessary
Willingness to travel (up to 20%, including flying to other sites worldwide) and potential time at sea supporting marine systems
Ability to lift 30 lbs
Ability to work at heights
Ability to drive (active valid driver's license)
