## Description

We're seeking an experienced Protection Relay Engineer/Specialist to join our Memphis team. This role will focus on the design, configuration, commissioning, and support of SEL-based protection and automation systems for high-reliability power infrastructure supporting our AI compute facilities.

Responsibilities:

- Perform detailed configuration and programming of SEL protective relays (e.g., SEL-751, SEL-787, SEL-700G, etc.) using acSELerator QuickSet and SEL Grid Configurator.

- Develop and implement custom automation logic in SEL RTAC platforms using acSELerator Architect, IEC 61131-3 languages (Structured Text, Ladder Logic), and SEL Logic Engine.

- Design and test SCADA communication protocols including DNP3, Modbus, IEC 61850 GOOSE/MMS, and SEL protocols over Ethernet and serial interfaces.

- Conduct factory acceptance testing (FAT), site acceptance testing (SAT), relay setting validation, and end-to-end functional verification.

- Generate comprehensive documentation: one-line diagrams, logic diagrams, setting files, HMI screens, and commissioning reports.

- Provide technical support during system energization, troubleshooting, and post-commissioning maintenance.

- Collaborate with project managers, SCADA engineers, and field crews to ensure seamless integration and schedule compliance.

- Remain current with SEL firmware updates, NERC CIP cybersecurity requirements, and industry best practices.

Basic Qualifications:

- Advanced proficiency in acSELerator QuickSet, Architect, and RTAC Web Interface.

- Demonstrated ability to develop complex automation sequences, synchrophasor applications, and remedial action schemes.

- Expertise in relay event analysis using SEL SynchroWAVE and Event Reporter.

- Familiarity with IEC 61850 configuration via SCL files (SCD, ICD, CID).

- SEL Authorized Training (e.g., SEL-5030, SEL-5033) preferred; PE license a plus but not required.
