The System Testing Engineer is a specialist-level individual contributor responsible for executing and driving advanced system testing activities for substation automation and protection systems. This role centers on IEC 61850 (Edition 2.1), top-down engineering, and multi-vendor relay interoperability, with a modern mandate to integrate AI-agentic workflows into the testing lifecycle.
Job Description
Core Focus: Test Strategy & Execution
•
Test Case Design: Architect comprehensive, high-coverage test suites for complex protection and control logic.
•
Automation Scripting: Develop and maintain robust automation scripts to enhance test cycle speed and consistency.
•
Defect Tracking: Perform rigorous defect lifecycle management, from identification and root cause analysis to final validation.
AI-Driven Testing Workflow & Skills
•
Requirements to Tests: Generate accurate test cases and automation scripts directly from technical requirements using AI-powered tools.
•
Validation: Review and validate AI-generated automation scripts for accuracy, maintainability, and standard compliance.
•
Defect Intelligence: Utilize AI-driven tools for automated defect triage, trend analysis, and comprehensive summarization of complex system issues.
•
Exploratory Testing: Apply advanced prompt engineering techniques to conduct AI-guided exploratory testing to uncover edge-case defects.
Technical Responsibilities
•
Troubleshooting: Serve as the Single Point of Contact (SPOC) for IEC 61850 inquiries. Perform deep-dive analysis of communication logs (GOOSE, MMS, SV) and relay event records to resolve multi-vendor integration challenges.
•
Technical Collaboration: Review communication matrices and SCL configurations to identify design gaps early.
•
Documentation: Maintain detailed, audit-ready test evidence and documentation for project certification and delivery.
Required Skills and Experience
•
Domain Expertise: 3 to 6 years deep hands-on experience with IEC 61850 (Edition 2 & 2.1) and substation automation/protection systems.
•
Integration Skills: Proven experience in testing and troubleshooting systems with multi-vendor IEDs/Relays.
•
Automation & Scripting: Proficiency in scripting (Python, Shell, or similar) and experience with test automation frameworks.
•
AI Competency: Demonstrated ability to apply AI based tools for test design, script generation, and defect analysis. Strong command of prompt engineering to drive technical workflows.
•
Analytical Ability: Exceptional skill in log analysis, protocol trace interpretation, and root-cause identification.
Preferred Qualifications
•
Background in power systems, protection and control, or digital substation engineering.
•
Experience with SCL engineering and IEC 61850 system configuration tools.
•
Experience managing complex test environments and high-volume defect tracking in a specialist capacity.
