## Description

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.
