Job Posting
About the Role We are a leading provider of chip and silicon IP solutions, seeking an exceptional Senior Engineer with signal integrity and package design expertise to join our Memory Interface engineering team. This full-time role involves developing products that boost data speed and security. Reporting to the VP of Engineering, you'll focus on SI/PI modeling, analysis, and simulations for high-speed DDR applications up to 12800+ MT/s.
Key Responsibilities Develop SI/PI methodologies; collaborate on studies and package designs for DDR products. Define specs and requirements (e.g., packaging, PCB routings, decoupling, simulations, jitter analysis) with design/validation teams. Guide design team via SI/PI studies, simulations, and correlations for top SI performance (e.g., optimal RMT scores). Partner with customers on optimal SI/PI solutions. Support debug and lab bring-up.
Requirements Qualifications MS/PhD in Electrical Engineering; 10+ years experience, including DDR4/DDR5 focus. Experience simulating high-speed memory (DDR4/DDR5) and/or SERDES. Strong in EM and transmission line theory. Expertise in equalization (FIR/FFE/DFE/CTLE). Proficient in package/PCB design: editing APD/Allegro files, SI/PI-driven BGA, system simulations. Hands-on correlation of simulations with lab measurements (scopes, TDRs, VNAs). Desirable:
Server system knowledge (CPUs to DRAMs); crosstalk/jitter in source-synchronous interfaces for low BER. Skilled in Spice, ADS, HFSS, Q3D/PowerSI. Plus:
Red Hawk/Totem, XcitePI, Virtuoso familiarity. Valued:
Lab experience with passive components, margins, noise (scopes, VNA/TDR). Preferred:
Basic high-speed link circuit knowledge. Excellent communication, writing, presentation skills for customers/teams. Innovative, self-motivated team player with leadership.
