About the RoleWe are seeking a versatile QA Engineer to bridge the gap between our cutting-edge EEG hardware and our software ecosystem. In this role, you will be the gatekeeper of quality, ensuring that our biomedical devices, firmware, and user-facing applications function seamlessly together. You will collaborate closely with the Hardware and Software teams to design test strategies, debug complex integration issues, and validate performance from the circuit board level up to the application layer.Key ResponsibilitiesTest Planning & Strategy: Design, develop, and maintain comprehensive test plans and test cases that cover the full product lifecycle (Hardware, Firmware, Software). Define acceptance criteria for new hardware revisions and firmware updates.Execution & Validation: Perform functional, regression, stress, and system integration testing on EEG headsets and supporting software. Validate hardware performance (signal quality, battery life, connectivity) and firmware stability. Execute connectivity testing (Bluetooth/BLE, USB) for reliable data transmission.Debugging & Automation: Identify, document, and track defects (e.g., JIRA). Contribute to automated testing frameworks (Python/scripting) and automate regression tests. Analyze test results, produce quality reports, and recommend improvements.Requirements (Must-Have): Bachelor’s in CS, EE, Biomedical Eng. or related. 3+ years QA/Testing focused on HW/SW integration. Strong embedded systems and firmware understanding; scripting/programming (Python, C/C++). Experience with UART, SPI, I2C, USB, Bluetooth Classic/BLE. Familiar with oscilloscopes, logic analyzers, multimeters. Excellent problem solving and English communication.Preferred: EEG/biosignals or medical/wearables experience; read schematics/PCB; MCU experience (Microchip dsPIC, Nordic nRF, Qualcomm); CI/CD, cloud testing, Agile QA.
