Operational Technology Engineer

SpaceXAI’s mission is to create AI systems that can accurately understand the universe and aid humanity in its pursuit of knowledge. Our team is small, highly motivated, and focused on engineering excellence. This organization is for individuals who appreciate challenging themselves and thrive on curiosity. We operate with a flat organizational structure. All employees are expected to be hands-on and to contribute directly to the company’s mission. Leadership is given to those who show initiative and consistently deliver excellence. Work ethic and strong prioritization skills are important. All employees are expected to have strong communication skills. They should be able to concisely and accurately share knowledge with their teammates.

SpaceXAI 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 our next-generation hyperscale data center campuses and co-located power generation facilities. You will architect and deliver resilient OT infrastructure supporting BMS, EPMS, SCADA, PLC, and related OT systems capable of supporting ultra-dense AI compute loads, massive power infrastructure, and aggressive deployment timelines that redefine industry standards. This is a high-impact, high-ownership role for an exceptional engineer who thrives in fast-paced, technically demanding environments. You will combine deep expertise in industrial automation, control systems, and mission-critical infrastructure with exceptional speed of execution, while seamlessly collaborating across mechanical, electrical, facilities operations, networking, and construction teams to deliver the control backbone that powers the future of AI.

• Own end-to-end OT critical infrastructure design, programming, configuration, commissioning, sustainment, and ongoing optimization. Deliver high availability OT infrastructure for critical hyperscale cooling & power control systems, including datacenter facility networks (MDFs/IDFs), industrial control networks (PLCs, turbines, etc.), and server rooms with switches/hosts/virtualization.Provide on-call network infrastructure support for BMS, EPMS, SCADA, PLC, and related systems (connectivity, addressing, protocol transport, troubleshooting at Layers 1–3/4).

• Hands-on design and sustainment of Juniper fiber/copper networks in OT/facility environments (EX/QFX series preferred), including segmentation, VRFs, and integration with industrial control networks.

• Design, implement, and secure OT networks and communications (BACnet, Modbus, OPC UA, MQTT, Ethernet/IP, and related protocols) while driving robust segmentation, monitoring, and cybersecurity practices.

• Drive cross-functional multidisciplinary coordination with mechanical, electrical, structural, facilities operations, IT/OT networking, and construction teams to ensure seamless integration of control systems with overall campus infrastructure.

• Perform advanced troubleshooting, root-cause analysis, and continuous improvement of OT systems to maximize availability, and operational resilience.

• Deliver rapid, high-quality responses to field issues, design reviews, RFIs, and operational needs while maintaining rigorous documentation, change control, and design intent.

• Identify and implement innovative solutions in industrial automation, advanced monitoring, predictive analytics readiness, and standardized control architectures to support SpaceXAI’s aggressive growth
