Hardware & Embedded Software Lead Engineer I lead the complete technical development of complex embedded products, acting as both the Hardware Design Engineer and Embedded Software Engineer throughout the project lifecycle. My responsibilities include system architecture definition, component selection, power design, schematic capture, multilayer PCB layout, signal and power integrity analysis, firmware development, driver implementation, communication protocols (CAN, LIN, UART, SPI, I2C), system integration, prototype validation, and manufacturing support. For large multidisciplinary projects, I coordinate the overall technical direction, manage cross-domain integration between hardware, firmware, and mechanical design, and ensure the final product meets performance, reliability, and production requirements. In many projects, I serve as the technical lead, transforming complex concepts into reliable, production-ready products.
