Senior PPC QA Engineer - Test Automation

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 completeTranslate requirements and interface specifications into test scenarios, acceptance criteria, and traceable test casesDesign, implement, and maintain reusable automated test suites and supporting frameworks for PPC control models, software components, interfaces, and regression workflowsConfigure and run simulation-based tests using MATLAB/Simulink and relevant electrical models or test environmentsVerify expected active/reactive power, voltage/frequency, dispatch, protection-support, and other assigned control responsesTest PPC interfaces to power meters, WTGs, third-party equipment, and BESS controllers against the agreed specificationAssess performance-related behavior, including scan rate, latency, timing, and signal handling, against project acceptance limitsAnalyze outputs, signals, logs, and plots; report failures with reproducible steps, relevant configuration, and diagnostic evidenceVerify fixes, maintain regression coverage, and contribute to release-level validation and quality reportingMaintain regression suites and test results so that model or software changes can be compared across versionsCollaborate 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 testingExperience with MATLAB/Simulink testing, simulation harnesses, or model-based verificationProficiency in Python for test orchestration, data analysis, plotting, and report generationProficiency in CI/CDProficiency in programming or scripting to produce and maintain test code and automation tools, not only execute manual test proceduresSkills in designing test cases from requirements and interface specifications and identifying meaningful edge and failure casesExpertise in scripting or programming for test automation and result processingBackground in testing embedded, control, simulation, industrial, or other system-integrated softwareCapability to analyze time-series signals, logs, test outputs, and performance measurementsShowcase of clear defect reporting, test documentation, and collaboration with developers through issue resolutionEnglish 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-throughFamiliarity with electrical simulation tools such as PSCAD, PowerFactory, or PSS/EExperience with CI integration, automated regression, hardware/software-in-the-loop, or lab-based testingBackground in testing controller interfaces with third-party equipment, including timing and communication performance We offer We gather like-minded people:Top tech minds driving innovation in AI, cloud and digital platform modernizationSupportive team and agile, startup-like cultureHybrid by design mode and opportunity to work remotely within PolandChance to work abroad for up to 60 days annuallyBusiness-driven relocation opportunitiesWe provide growth opportunities:Career development programsThought leadership, mentoring, soft skills and well-being programsCertification (Anthropic, Gemini, GCP, Azure, AWS)English classesWe cover it all:Stable payParticipation in the Employee Stock Purchase Plan with a 15% discountBenefits package (health insurance, multisport, shopping vouchers)Referral bonuses up to $2,000Offices featuring entertainment and relaxation zones, table tennis and football, free snacks, coffee and moreCorporate, social and well-being eventsPlease, note:Benefits listed above are available to employees onlyWe are open for working with Contractors.
