# Hardware Systems Engineer - EMI Technology

- **Company:** Apple Inc.
- **Location:** Cupertino, CA, United States
- **Experience:** Expert
- **Contract:** Permanent contract
- **Skills:** Systems Engineering, Software Debugging, Signal Integrity, Systems Architecture, Hfss, Hardware Testing, Ansys
- **Published:** July 30, 2026
- **Apply:** https://www.techcareers.com/job.asp?id=3336312039&tx=KK6363FFJ&pt=1&aff=0B19D771-A501-4A5E-8338-2A822B784D54&utm_source=Job%20Feed&utm_medium=textkernel&utm_campaign=DE&utm_term=0B19D771-A501-4A5E-8338-2A822B784D54

## About the Role

* Bachelor's or Master's Degree in EE or related field and minimum 5 years of industry experience
 * Strong experience in 3D EM simulations for debugging and mitigating complex EM coexistence issues
 * Hands-on experience in EM and circuit simulation tools: Ansys HFSS/Maxwell/SIWave, CST, ADS/Spice/Spectre, Cadence/Sigrity
 * Strong academic background in EM theory and coupling mechanisms is a must
 * Strong EE fundamentals, * PhD EE
 * Hands-on experience in hardware board-level testing, validation, and with lab equipment (near field scanning, spectrum analyzers, VNAs, scopes)
 * Knowledge of Power and Signal integrity
 * Knowledge of switching DC-DC converters
 * Ability to relate electrical performance to physical layout
 * Excellent collaborative and communication skills

## Description

In this role, you will identify, analyze, and mitigate EMI between subsystems to ensure co-existence. You will characterize and debug system-level EMI coexistence and RFI desense issues, leveraging both 3D EM and circuit simulations - spanning frequency and time domains alongside hands-on hardware validation using tools such as near-field scanners, spectrum analyzers, and VNAs. You will model the various subsystems on the system to assess their EMI impact, while developing design guidelines that inform board layout, system architecture, and product bring-up.

Working across multi-functional teams, you will define EM performance requirements and continuously improve design methodologies to ensure robust subsystem coexistence within the system.
