Senior Signal Integrity / Power Integrity Engineer

As a Senior SI/PI Engineer, you will be the ensuring the high-speed performance and reliability of our next-generation hardware. You will lead the analysis of complex PCB stack-ups, high-speed SerDes interfaces (PCIe Gen 5/6, DDR4/5, Ethernet), and power distribution networks (PDN). Your mission is to bridge the gap between theoretical EM physics and physical hardware manufacturing.

Key Responsibilities

● Use Ansys SIwave to perform automated SYZ-parameter extraction for complex, high-density interconnects (HDI).

● Conduct DC IR-drop analysis, AC impedance profiling of PDNs, and decoupling capacitor optimization to meet target impedance goals.

● Define PCB layer counts, dielectric materials and trace geometries to manage impedance and minimize insertion/return loss.

● Use SIwave’s near-field and far-field solvers to identify resonance issues and radiation hotspots on the PCB before lab testing.

● Translate simulation findings into actionable routi...
