Contract Type: [6–12 months – extendable]

Department: Hardware Engineering / Signal Integrity

Overview:

We are seeking a Contract Signal Integrity Engineer with expertise in S-Parameter Analysis and/or PCB Extraction to support high-speed PCB and package design, modeling, and simulation work. The role involves developing accurate high-frequency models through EM extraction, S-parameter characterization, and signal integrity analysis.

- Generate and validate Touchstone (.snp) models for components, transmission lines, and interconnects.

- Analyze S11/S21, return loss, and insertion loss characteristics using simulation and measurement data.

- Use EM simulation tools (e.g., HFSS, Clarity, SIwave, CST, ADS Momentum) to perform 3D EM extraction and parameterized model generation.

- Collaborate with PCB layout and design teams to integrate extracted models into system simulations.

- Correlate measurement data (VNA) with simulation results to verify model accuracy.

- Document procedures, maintain model libraries, and support design validation teams with model updates.

Required Skills & Experience:

- Strong understanding of S-Parameters, scattering parameters, and network parameter theory.

- Hands-on experience with RF characterization and VNA measurements.

- Proficiency in one or more EM extraction/field solver tools (e.g., Cadence Clarity, Ansys HFSS/SIwave, CST Studio, Keysight ADS, Synopsys Raptor, or similar).

- Experience with PCB parasitic extraction, EM modeling, and high-frequency simulation.

- Solid background in signal integrity (SI) and power integrity (PI) principles.

- Bachelor’s or Master’s degree in Electrical Engineering, Electromagnetics, or related field.

Desirable Skills:

- Experience with parameterized model generation or automated extraction workflows.

- Knowledge of SPICE, IBIS-AMI, or other system-level modeling standards.

- Familiarity with high-speed interfaces (PCIe, DDR, SerDes, USB, Ethernet).

- Scripting or automation experience (Python, MATLAB, SKILL, or TCL).
