Protection & Controls Engineer

Join the High Power Engineering team at SpaceXAI 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.

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.
• 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.
• Collect and analyze fault and disturbance records; 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.
• Support NERC PRC evidence and testing where required.
• Work with field technicians, operators, and contractors during outages, switching, and troubleshooting.

Basic Qualifications:

• Bachelor's degree in electrical engineering, computer engineering, or another engineering discipline.
• 3+ years of protection and controls experience on medium- or high-voltage systems.

Preferred Skills and Experience:

• 5+ years in a protection and controls role at a utility, independent power producer, EPC, relay manufacturer, or hyperscale / colocation data center operator.
• Hands-on experience with Schweitzer Engineering Laboratories (SEL) relays and software.
• Experience with short-circuit and coordination studies in ETAP, ASPEN OneLiner, CAPE, SKM, or EasyPower.
• Familiarity with DNP3, Modbus, IEC 61850, IEEE C37.118, and IEEE C37.111.

Additional Requirements:

• Perform hands-on work in all environments.
• Work extended hours and weekends as needed.
• Remain focused in hazardous environments while wearing PPE.
• Lift up to 25 lbs. unassisted.
• Provide 24/7 on-call support for emergencies.
• Willing to work on-site in Memphis, TN.
