About the Role

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.

ABOUT THE ROLE:

Join the power generation engineering team to design, commission, and maintain plant control systems. As a Controls Engineer, you will own BOP PLC/HMI and the control-room SCADA picture that brings generation and balance-of-plant into one operating view — Solar, 6000, and BOP on a single set of screens. You will work from control philosophy through commissioning and ongoing reliability, hands-on at the panel and in the control room. The position is based in Memphis, TN, with potential travel to other sites. 

RESPONSIBILITIES: 

  • Own BOP PLC and HMI design, programming, and commissioning for power generation balance-of-plant systems (fuel gas, water, compressed/instrument air, HVAC, cooling, electrical auxiliaries, and related process/utility systems) 
  • Design and maintain the plant SCADA architecture so operators have one operating picture in the control room integrating Solar, 6000, and BOP — graphics, alarms, historian, and situational awareness on a single platform 
  • Develop control philosophy, control narratives, I/O lists, network drawings, cause-and-effect diagrams, and HMI/SCADA standards for reuse across the facility 
  • Specify PLC, HMI, SCADA, remote I/O, industrial networking, and interface hardware; define data exchange with OEM turbine/generation controllers (Solar and 6000) and with electrical protection, metering, and plant systems 
  • Program, test, and troubleshoot PLC logic and HMI applications (IEC 61131 — ladder, function block, structured text as applicable) 
  • Integrate OEM packages and third-party systems into plant SCADA using industrial protocols (Modbus, DNP3, OPC UA, IEC 61850, and others as required) so Solar, 6000, and BOP operate as one system 
  • Commission controls: I/O checkout, loop checks, functional testing, HMI validation, alarm rationalization, and start-up support; stay hands-on with technicians and operators 
  • Support day-to-day operations: troubleshooting, sequence issues, bad actors, and control changes under MOPs/MOC 
  • Maintain configuration management for PLC/HMI/SCADA programs, as-left files, firmware, and network documentation
