Perform functional testing of embedded boards — power-on, boot sequence, peripheral checks
Flash and program microcontrollers (Arduino, STM32, ESP32, PIC, AVR, etc.) using JTAG, SWD, UART, or ISP interfaces
Execute test plans and test cases for hardware validation
Use oscilloscopes, multimeters, logic analyzers, function generators for debugging
Test communication interfaces: UART, SPI, I2C, CAN, USB, RS485
Conduct environmental and stress testing (temperature, vibration) where applicable
Log test results, identify failures, and escalate to the engineering team

📋 Documentation & Quality

Maintain production records, test logs, and defect reports
Follow SOPs and work instructions accurately
Coordinate with design engineers for design for testability (DFT) feedback
Support regulatory and compliance testing (CE, FCC, RoHS) if required
