Job Title: Contract Signal Integrity / S-Parameter Modeling EngineerLocation: Remote (with occasional on-site visits)Contract Type: (6–12 months – extendable)Department: Hardware Engineering / Signal IntegrityOverview:
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.

This is a remote contract position with occasional visits to the client’s site as required.
Key Responsibilities:

-Perform S-Parameter modeling and frequency-domain analysis of high-speed interconnects, packages, and PCB structures.
-Conduct EM/field solver extraction for parasitic and impedance modeling (RLC/RC extraction, crosstalk, delay).
-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).
