Fidus Systems

7h•$105,000 - $155,000

About The Position

The Senior Signal Integrity and Power Integrity Specialist plays a critical role in ensuring the performance, reliability, and compliance of high-speed electronic systems designed by Fidus. You will lead and support SI/PI analysis from early architecture through final validation, working closely with hardware designers, PCB layout, FPGA, and system teams to optimize signal quality and power distribution. This role is ideal for someone who thrives on solving complex high-speed challenges, enjoys working across multiple industries, and takes pride in delivering robust, production-ready designs backed by strong analytical and lab validation skills. At Fidus, you’ll work on complex, high-speed systems across a diverse set of industries including telecommunications, wireless devices, biomedical instruments, avionics, maritime, and more . You’ll contribute to projects ranging from evaluation boards and reference designs to high-speed backplanes and systems involving DDR memory interfaces and SERDES . Your work will directly influence product performance, manufacturability, and compliance. In practice, this means engaging from early concept and stack-up definition through simulation, layout guidance, lab validation, and final product release. You won’t be limited to a single application domain — you’ll work where the technology demands deep SI/PI expertise.
