Role Posting Log in to save

The Signal Integrity Engineer – Memory Interface joins the team developing SoCs used within mobile devices. This role focuses on memory interface signal integrity from package to board, specifically addressing DDR and LPDDR interfaces. The engineer will perform electrical and physical design of memory systems, including extraction and validation of packages and motherboards. Key responsibilities involve conducting end-to-end signal and power integrity simulation studies for die, interposer, package, PCB, and PMU components to meet strict timing and voltage specifications. The candidate will collaborate with circuit and controller teams to optimize designs, provide floorplan guidelines, and perform feasibility studies for next-generation signaling schemes. Required skills include 2D/3D EM simulation tools, transmission line theory, Python programming, and experience with lab equipment like VNA, TDR, real-time scopes, and spectrum analyzers to correlate simulations with silicon measurements.
