Role Overview

Responsible for developing and executing electromagnetic and signal-integrity simulation workflows for PCB designs, analyzing interconnect behavior, parasitic effects and signal quality, and generating technically validated simulation evidence.

Key Responsibilities

• Perform electromagnetic simulations of PCB traces, vias, transmission lines, return paths and interconnect structures.

• Analyze impedance, insertion loss, return loss, crosstalk, coupling and signal propagation.

• Perform resistance, inductance and capacitance extraction using FastHenry and FasterCap.

• Use OpenEMS for full-wave electromagnetic simulations and S-parameter extraction.

• Use ngspice for circuit-level transient and AC analysis incorporating extracted parasitics.

• Analyse clock and high-speed digital signals, including propagation delay, skew, rise/fall time and waveform-based jitter metrics.

• Develop Python-based automation and post-processing workflows using libraries such as scikit-rf, NumPy and SciPy.

• Correlate simulation results with analytical calculations and trusted reference data.

• Document simulation assumptions, model limitations, results and verification evidence.Required Skills

• Strong fundamentals in signal integrity, electromagnetic theory and high-speed PCB design.

• Understanding of transmission lines, impedance matching, reflections, crosstalk and return-current paths.

• Practical experience with PCB parasitic extraction and S-parameter analysis.

• Experience with at least one EM simulation tool; familiarity with OpenEMS is desirable.

• Knowledge of FastHenry, FasterCap and ngspice, or equivalent tools.

• Python scripting for simulation automation and data analysis.

• Familiarity with Touchstone files, frequency-domain and time-domain analysis.Preferred Qualifications :

• Bachelor's or Master's degree in Electrical/Electronics Engineering.

• 5+ years of relevant experience in SI, PI, electromagnetic simulation or high-speed PCB engineering.

• Experience with automotive electronics, embedded systems or high-speed digital interfaces.
