Summary
The Hardware Systems Engineer will focus on iPhone Special Technology within the Hardware department. This role involves modeling, simulating, and debugging electrical systems including DC-DC converters, EMI coexistence, and power integrity. The engineer will design and analyze power delivery solutions, characterize and debug EMI/RFI issues, and perform feasibility studies and testing. Responsibilities also include providing guidance on system architecture, board layout, and factory builds, as well as partnering with cross-functional teams on power architecture and IP specifications. A key aspect is developing and improving design methodologies for robust coexistence and minimal EMI.
Description
Model, simulate, and debug electrical systems across DC-DC, EMI coexistence, and power integrity — in both frequency and time domains
Design and analyze power delivery solutions, including DC-DC converters, passives, and PDNs, and assess their EMI potential
Characterize and debug system-level EMI/RFI desense and coexistence issues using 3D EM and circuit simulation plus hands-on hardware validation
Perform design feasibility studies, testing, verification, and system bring-up
Provide design guidance for system architecture, board layout, product bring-up, debug, validation, and factory builds
Partner with cross-functional stakeholders on power architecture, IP specs, and performance
Develop and improve design methodologies to achieve robust coexistence and minimal EMI
BS/MS in Electrical Engineering or related field
Strong EE fundamentals and problem-solving skills
Ability to relate electrical performance to physical layout and system-level behavior
Hands-on experience with EM and/or circuit simulation tools (e.g., Ansys HFSS/Maxwell/SIWave, CST, ADS/SPICE/Spectre, Cadence/Sigrity)
Board-level lab experience with standard equipment (oscilloscopes, spectrum analyzers, VNAs, electronic loads, signal generators)
Familiarity with system-level EMI/RFI desense and coexistence
MS/PhD in a relevant field, or equivalent industry experience
Background in EM theory and coupling mechanisms; 3D EM simulation for debugging coexistence issues
Experience with switching DC-DC converters, LDOs, magnetics, and power management ICs
Experience with power distribution network (PDN) design and power/signal integrity
Proficiency using AI/ML such as applying statistical or machines learnings techniques to HV test data, using optimization methods to accelerate PI/EMI/DCDC design iteration, and leveraging LLM based tools to speed up scripting, data analysis, and documentation.
Some scripting experience is good to have (Python)
Possessing a mindset of scientific and systematic approach to troubleshooting multi-disciplinary system issues is a strong plus
Excellent cross-functional teamwork skills
