Firmware Engineering Intern Role Overview As a Firmware Engineering Intern on the Optical Transceiver Module or Active Electrical Cable (AEC) Firmware team, you will contribute to embedded software that helps bring up, validate, and improve high-speed connectivity products. You will work across C and Python codebases, build practical debugging skills, and collaborate with firmware, hardware, and validation engineers to turn requirements into reliable product functionality. This is an opportunity to apply your coursework and embedded firmware experience to real products supporting the next generation of rack-scale AI infrastructure. You will gain hands-on exposure to firmware development, lab testing, automation, and system-level problem solving while learning in a fast-moving environment where interns are encouraged to grow and make meaningful contributions. Key Responsibilities Firmware Development Implement and enhance embedded firmware in C for optical and active electrical cable products. Develop Python scripts and tools for test automation, device configuration, log parsing, and data analysis. Translate requirements into clear, maintainable code with guidance from experienced firmware engineers. Bring-Up, Debugging, and Validation Support firmware bring-up on embedded platforms and assist with board- and system-level debugging. Execute functional, regression, and interoperability tests; document results and track issues. Use lab equipment and software tools to isolate failures, verify fixes, and improve product quality. Embedded firmware experience through coursework, research, personal projects, or a prior internship. Proficiency in C and Python. Understanding of embedded systems concepts, microcontrollers, memory, interrupts, and peripheral interfaces. Demonstrated ability to debug methodically, learn quickly, and communicate technical findings clearly. Preferred Qualifications Experience developing firmware for an ARM-based microcontroller, such as STM32. Fa…
