xAI is seeking an exceptional Operational Technology (OT) Engineer to own the design, implementation, optimization, and long-term reliability of industrial control and monitoring systems across next-generation hyperscale data center campuses and co-located power generation facilities. You will architect and deliver resilient OT infrastructure supporting Building Management Systems (BMS), Electrical Power Management Systems (EPMS), SCADA, PLCs, and related systems capable of supporting ultra-dense AI compute loads, massive power infrastructure, and aggressive deployment timelines.
Key responsibilities include:
- End-to-end OT critical infrastructure design, programming, configuration, commissioning, and optimization for hyperscale cooling and power control systems
- Hands-on design and sustainment of Juniper fiber/copper networks in OT/facility environments (EX/QFX series preferred), including segmentation and VRF integration
- Design, implement, and secure OT networks and communications using BACnet, Modbus, OPC UA, MQTT, Ethernet/IP, and related protocols with robust segmentation and cybersecurity practices
- Cross-functional coordination with mechanical, electrical, structural, facilities operations, IT/OT networking, and construction teams
- Advanced troubleshooting, root-cause analysis, and continuous improvement of OT systems to maximize availability and operational resilience
- Rapid response to field issues, design reviews, RFIs, and operational needs with rigorous documentation and change control
- Identify and implement innovative solutions in industrial automation, advanced monitoring, and predictive analytics
- Mentor junior engineers and technicians while contributing to OT design and programming standards
Required: Bachelor's degree in Controls Engineering, Automation Engineering, Electrical Engineering, Mechatronics, Computer Engineering, or related technical field (or equivalent practical experience).
Preferred: 5+ years progressive hands-on experience as Controls/OT/Automation Engineer on data centers, semiconductor fabs, power plants, or mission-critical facilities. Direct experience designing and sustaining OT infrastructure for BMS, EPMS, and SCADA systems. Systems administration for virtualization (Proxmox/VMware), Juniper networks, and SQL databases. Experience hardening OT servers (RAID, UPS-backed, isolated management planes). Familiarity with industrial communication protocols and OT network design/segmentation. Track record of delivering complex control system projects with exceptional speed and quality in fast-moving environments. OT cybersecurity principles and secure remote access experience.
