• Transformer protection
• Transmission line protection
• Bus differential protection
• Breaker failure protection
• Perform relay coordination studies to ensure proper operation between upstream and downstream devices
• Apply protection philosophies aligned with utility standards and grid reliability requirements

Control System Design

• Develop AC/DC control schematics for substation equipment
• Design breaker control, interlocking, and alarm logic
• Integrate protection systems with SCADA/RTU and substation automation systems
• Support communication protocols such as DNP3 and IEC 61850

System Studies & Analysis

• Perform short circuit, coordination, and arc flash studies using tools such as ETAP, ASPEN, or CAPE
• Analyze system disturbances, fault events, and relay misoperations
• Support root cause analysis and corrective action development

Testing & Commissioning Support

• Provide engineering support during relay testing and substation commissioning
• Review and validate:
• Secondary injection test results
• End-to-end relay testing
• Support energization of new and upgraded substations
• Coordinate with field technicians and commissioning teams

Standards & Compliance

• Ensure designs meet utility standards and industry best practices
• Support compliance with applicable NERC reliability standards
• Maintain accurate documentation for relay settings, logic diagrams, and system changes

Capital Project Support

• Support engineering design and execution of substation capital projects
• Coordinate with physical substation engineers, project managers, and construction teams
• Review vendor/contractor drawings and as-built documentation

Operational Support

• Provide engineering support during system faults and outage restoration
• Assist system operations teams with real-time troubleshooting
• Participate in post-event analysis and reporting

Required Qualifications

• Bachelor's degree in Electrical Engineering or related field
• Experience in protection & control engineering within utility or industrial power systems
• Strong understanding of power system protection principles and relay coordination
• Hands-on experience with relay platforms such as SEL, GE Multilin, or Siemens
• Knowledge of AC/DC control circuits and substation automation systems
• Experience with power system study tools (ETAP, ASPEN, CAPE, or equivalent)
• Strong analytical, troubleshooting, and problem-solving skills

Preferred Qualifications

• Experience with high-voltage substations (69kV-345kV)
• Familiarity with SCADA/RTU integration and communication protocols (DNP3, IEC 61850)
• Experience supporting transmission or substation capital projects
• Exposure to utility operations in complex or urban environments
• Professional Engineer (PE) license or ability to obtain

Core Competencies

• Power system analysis and fault evaluation
• Relay protection coordination and settings development
• Attention to detail in safety-critical environments
• Strong communication with field, operations, and engineering teams
• Ability to perform under outage and time-sensitive conditions
• Technical documentation and reporting

Work Environment

• Office-based engineering with regular field visits to substations
• Occasional night/weekend work during outages, testing, or commissioning activities
• Collaborative environment with engineering, operations, and construction teams
