Preferred Qualifications

Familiarity with common lab equipment and measurement techniques including network analyzers, LCR meter, power supply/amplifiers, oscilloscopes, etc. Experience in creating mathematical, computational, and numerical models for reduced order and more complex thermal analysis Familiarity with statistical analysis of design perturbations Experience with transformer theory and modeling Understanding of physics of magnetic materials Working knowledge in heat transfer M.S. + 3 yrs experience or Ph.D. (preferred) in material science or power electronics (ECE) program, or related area (e.g. engineering physics)

Description

This is an opportunity to participate in a multifaceted and outstanding engineering group at one of the world’s leading companies. Candidates will have the opportunity to work on highly technical topics related to some of Apple’s latest products in power technology. In particular, the role includes participation in the design, simulation, testing and analysis of current and future wireless power products. The role requires broad knowledge of finite element analysis (FEA) modeling (using commercial tools) of the magnetic field. The candidate should have basic knowledge of the physics of magnetic materials, Maxwell’s equations, and finite element analysis. This is a unique opportunity in designing inductive power links with mass production intent. Candidates with a creative attitude and who are eager to undertake new challenges will find this role especially fulfilling.

Responsibilities

Drive new techniques in simulation and measurement for improved efficiency and accuracy Electromagnetic analysis of various geometrical structures (FEA) Aid in risk assessments and co-existence analysis Rigorously document designs and key parameters Use of analytic tools (such as Excel, Mathcad, Matlab) for basic sizing, weight, system performance Use of specialized thermal simulation software Analysis and verification of designs with Finite Element Analysis (e.g. COMSOL Multiphysics) Work with cross-functional team such as electrical engineers, mechanical designers and material scientists Experimental validation of designs via measurement of key parameters and correlation to simulation and analytic predictions Participate in material selection through experimental/theoretical investigations, working with external vendors, and other cross-functional teams to find optimized solutions
