Signal Integrity & EM Simulation Engineer at Turing

Signal Integrity & EM Simulation Engineer | Pay varies | Remote | Contract, ~13 weeks

About the role

This is a contract engagement with Turing. You'll develop and run electromagnetic and signal-integrity simulation workflows for PCB designs, analyzing interconnect behavior, parasitic effects and signal quality, and producing technically validated simulation evidence.

What you'll do

• Run electromagnetic simulations of PCB traces, vias, transmission lines, return paths and interconnect structures.
• Analyze impedance, insertion loss, return loss, crosstalk, coupling and signal propagation.
• Extract resistance, inductance and capacitance 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.
• Analyze clock and high-speed digital signals, including propagation delay, skew, rise/fall time and waveform-based jitter metrics.
• Build 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.

What you'll need

• 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.

Engagement details

• Start date: expected to start as soon as possible.
• Length: ~13 weeks, with potential for extension.
• Hours: 40 hours/week.
• Type: Contract.
• Selection process: one AI interview and one interview with the team.
