TL;DR · Signal Integrity Engineer, Memory Interface

Role Posting Log in to save

As a Signal Integrity Engineer – Memory Interface, you will join the team developing SoCs for mobile devices. You are responsible for memory interface signal integrity from package to board, specifically focusing on DDR and LPDDR interfaces. Your daily work involves the electrical and physical design of memory systems, including extraction and validation of packages and motherboards. You will perform end-to-end signal and power integrity simulation studies, model channels and power delivery networks, and conduct feasibility studies for next-generation signaling schemes. To succeed, you must utilize 2D/3D EM simulation tools, transmission line theory, and Python coding. You will also use lab equipment like VNA, TDR, real-time scopes, and spectrum analyzers to correlate simulations with silicon measurements while collaborating with cross-functional teams to optimize designs, provide guidance on floorplans, and improve product yield.
