• Constant improvements of SI models using data from lab measurements and/or modelling tool/methodology updates.
• Substrate and board layout SI guidelines creation, review and post layout SI extractions.
• Simulation automation, data gathering, analysis and visualization using JMP, MATLAB or similar tools.
• Opportunity to work in a dynamic cross-functional role to optimize package, PCB, ASIC, mixed signal circuit.

What we need to see:

• BS/MS-Electrical Engineering or equivalent experience with 3+ years of industry experience.
• Strong technical background in applied electromagnatics, transmission line theory and signal processing will be highly valued.
• SI work on one or more signaling standards like PCI express, USB, SATA, HDMI, HBM, DDR5, GDDR6, LPDDR5X, etc.
• Hands on use of 3-D modeling tools like ANSYS HFSS/Q3D, 2.5-D with ANSYS SIWAVE or similar and 2D such as Ansys2D.
• Familiarity with a system level timing or loss budget including silicon, package and board impairments.
• Familiarity with use of VNA, TDR, DSO, ParBERT and use of tools/applications like ADS, Ansys Designer, JMP, Matlab, Cadence Allegro will be a plus.

Ways to stand out from the crowd:

• Experience in interconnect electromagnetic model design for 200Gbps systems, particularly in backplane and midplane architectures.
• Hands-on expertise in characterizing and correlating high-speed interconnects including PKG, PCB, connectors and cable assemblies in the lab (including using VNA and, if necessary, probing).
• Ability to post process and analyze interconnect measured SI data, using statistics when necessary, to assess performance at production sites, enhancing data-driven decision-making.
• Knowledge of circuit design, board/pkg technology & design, link architecture, timing budget methodologies.
