Hardware Systems Engineer - EMI Technology

At Apple, we don't just create products, we create experiences that redefine what's possible. Our people are the driving force behind innovations that have transformed entire industries, and it's the unique perspectives and bold ideas they bring that make it all happen. From groundbreaking technology to our commitment to a more sustainable planet, everything we do is rooted in a desire to leave the world better than we found it.

We have an opportunity for a passionate and results-driven Electromagnetic Interference (EMI) Engineer to join our iPhone Hardware Engineering - System Technology team and help push the boundaries of what iPhone can do.In this highly collaborative role, you will partner with System Electrical Engineering (EE), Product Design (PD), and module teams, including camera, display, audio, and sensors, to design, model, simulate, and verify EMI coexistence across iPhone's subsystems.

Our team is creative and passionate about what we do and the products we make.

Come join us!

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.

Responsibilities:

Providing design guidelines and support to system architecture design, board layout, product bring up, debug, validation, and factory builds.

Developing and improving design methodologies to achieve minimal EMI

Characterizing and debugging results-oriented system level co-existence/RFI desense issues

Simulating and analyzing system high-speed circuits for signal integrity and their potential for EMI

Performing design feasibility study, design testing and verification, and system bring up.

Performing 3D-EM and circuit modeling and simulations in the frequency and time domains.

Designing and analyzing power delivery networks including modeling of dc-dc converters, and their potential for EMI

Working with multi-functional teams to define design requirements for improved EM performance

Preferred Qualifications

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

Minimum Qualifications

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
