Principal Digital Electrical Design Engineer

About the role

This position is for an experienced Circuit Card Assembly (CCA) Design Engineer. We’re looking for someone with a long detailed and proven track record designing 10+ multi-layer, low-loss, state-of-the-art high-speed CCAs. You need to understand customer requirements and derive requirements as needed to guide the design efforts. Most the circuits cards we develop have some or all of the following: large FPGAs, microprocessors, DDR2/3/4/5 memory, Flash memory, PCIe-Gen2/3/4, Ethernet 10/100/1000, USB 2.0/3.0, SD card, RS-232, RS-422, I2C, UARTs, and SPI interfaces supporting audio, video, GPS, etc. A strong knowledge of switching and linear power supplies is a must. Low inductance “across frequency” PDN design knowledge is a must. This engineer should be very familiar with high-speed (10+ Gbps SerDes) signal integrity, channel tuning and simulation (i.e. via impedance tuning, press-fit connector attach impedance tuning and cross-talk minimization, via back-drill technology, all aspects of 3D interconnect design and analysis). A detailed knowledge of raw PCB materials, PCB FAB processing, statistics, and PCB processing SPC is a plus. The tools we use include Altium Designer, Mentor Graphics HyperLynx SI/PI, LT Spice, Xilinx Vivado, Matlab, Polar Speedstack + SI9000, CST, HFSS, etc.
