Job Description Summary

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.
