Protection and Controls Engineer

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 High Power Engineering team to design, set, commission, and maintain protection and control systems for large electrical infrastructure. As a Protection & Controls Engineer, you will own schemes and settings from the transmission interconnection through distribution, on-site generation, and battery energy storage, down to medium- and low-voltage buses serving data halls and other mission-critical loads. The position is based in Memphis, TN, with potential travel to other sites.

RESPONSIBILITIES:

• Develop protection philosophy, one-line and three-line diagrams, DC control schematics, wiring diagrams, and relay panel layouts for the electrical system from the utility interconnection to facility buses.
• Calculate, implement, and maintain protective relay settings and logic for transmission lines, buses, power transformers, distribution feeders, generators, and battery energy storage / inverter-based resources.
• Specify relays, current and voltage transformers, trip circuits, lockout schemes, breaker-failure protection, and communications-assisted schemes (permissive, blocking, transfer trip).
• Perform short-circuit, protective-device coordination, and arc-flash studies; keep settings aligned with the study of record as the system changes.
• Commission protection systems: functional checks, primary and secondary injection, end-to-end scheme tests, and in-service timing checks. Use industry test sets (e.g. Doble, Omicron).
• Collect and analyze fault and disturbance records (COMTRADE and equivalent); recommend setting or scheme changes after events, misoperations, or staged tests.
• Maintain the settings management database, as-left files, and firmware/config control for in-service relays.
• Integrate protection with SCADA, RTUs, and plant/facility monitoring: DNP3, Modbus, IEC 61850 (including GOOSE), and IEEE C37.118 synchrophasors as applicable.
• Support NERC PRC evidence and testing where the interconnection or generation/storage fleet requires it (e.g. PRC-005, PRC-019, PRC-024, PRC-027).
