• Understanding of basic I/O protocols (SPI, I2C, UART, GPIO) and experience with DMA and interrupt handling in embedded systems.
• Working knowledge of microcontrollers (Arduino, Raspberry Pi) and/or FPGA (Xilinx or Intel).
• Working knowledge of testing instruments such as oscilloscopes, digital multimeter, function generator.
• Basic knowledge of electronic circuits and semiconductor technology.
• Ability to work in a startup environment and to work both independently and as a team player.
• Familiarity with test management and defect tracking tools (e.g., JIRA, Bugzilla).
• Proficiency in version control (Git, BitBucket).

Responsibilities

• Testing and silicon debug, including writing the necessary testing code, testing platform setup, and silicon screening and debugging.
• Design, develop, and maintain embedded software, including drivers and application code, to support device functionality and performance benchmarks.
• Identify and document test scenarios and conditions for functional testing of embedded software, ensuring comprehensive evaluation of firmware and hardware interfaces.
• Contribute to testing methodology and setup including probe card, packaged chip, and PCB testing.
• Analysis of signal integrity, noise, power, and other design issues.
• Record and document results, compare them with expected outcomes, and log defects in the defect tracking system.
• Reproduce and isolate issues within embedded systems, providing detailed documentation for troubleshooting and resolution.
• Work closely with the hardware and design teams to verify embedded system features and to help debug issues at the firmware and driver levels.
• Help with product demo setup and running different demo benchmark/showroom projects as needed.
• Hardware development on circuit board, system and user interface
