Signal Integrity and Electromagnetic Simulation Engineer (PCB Design)
Remote (Global)
November 10, 2026
Job description
**About Turing:
**Based in San Francisco, California, Turing is the world’s leading research accelerator for frontier AI labs and a trusted partner for global enterprises deploying advanced AI systems.
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.
Project Details:
- Contract Start Date: Expected to start as soon as possible
- Engagement: ~13 weeks (with potential chances of extension)
- Commitment - 40 hours/week
- Engagement Type: Contract
- Selection process: 1 AI Interview and 1 Interview with our team
