Description
We are looking for a Senior PPC QA Engineer specialized in Test Automation to design and automate verification of PPC control behavior, software integration, and related electrical-model releases. This role focuses on engineering test automation and evidence-based validation, rather than manual-only testing or general-purpose application QA. Responsibilities Engage during requirements and design reviews to identify testability gaps and shape verification strategy before implementation is complete Translate requirements and interface specifications into test scenarios, acceptance criteria, and traceable test cases Design, implement, and maintain reusable automated test suites and supporting frameworks for PPC control models, software components, interfaces, and regression workflows Configure and run simulation-based tests using MATLAB/Simulink and relevant electrical models or test environments Verify expected active/reactive power, voltage/frequency, dispatch, protection-support, and other assigned control responses Test PPC interfaces to power meters, WTGs, third-party equipment, and BESS controllers against the agreed specification Assess performance-related behavior, including scan rate, latency, timing, and signal handling, against project acceptance limits Analyze outputs, signals, logs, and plots; report failures with reproducible steps, relevant configuration, and diagnostic evidence Verify fixes, maintain regression coverage, and contribute to release-level validation and quality reporting Maintain regression suites and test results so that model or software changes can be compared across versions Collaborate with control developers, embedded developers, DevOps, and electrical-model engineers to clarify expected behavior and resolve defects Requirements 5+ years of experience in software QA or systems verification with a strong focus on automated testing Experience with MATLAB/Simulink testing, simulation harnesses, or model-based verification Proficiency in Python for test orchestration, data analysis, plotting, and report generation Proficiency in CI/CD Proficiency in programming or scripting to produce and maintain test code and automation tools, not only execute manual test procedures Skills in designing test cases from requirements and interface specifications and identifying meaningful edge and failure cases Expertise in scripting or programming for test automation and result processing Background in testing embedded, control, simulation, industrial, or other system-integrated software Capability to analyze time-series signals, logs, test outputs, and performance measurements Showcase of clear defect reporting, test documentation, and collaboration with developers through issue resolution English proficiency at B2 level or higher Nice to have Knowledge of grid-code or power-system test scenarios, such as active/reactive power response, frequency and voltage response, or fault ride-through Familiarity with electrical simulation tools such as PSCAD, PowerFactory, or PSS/E Experience with CI integration, automated regression, hardware/software-in-the-loop, or lab-based testing Background in testing controller interfaces with third-party equipment, including timing and communication performance
