• Proficiency in Python for test orchestration, data analysis, plotting, and report generation
• Proficiency in CI/CD processes
• Proficiency in programming or scripting to produce and maintain test code and automation tools
• Skills in designing test cases from requirements and interface specifications, 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
• 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

• 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 for comparison across model or software versions
• Collaborate with control developers, embedded developers, DevOps, and electrical-model engineers to clarify expected behavior and resolve defects
