This is an opportunity to participate in a multifaceted and outstanding engineering group at one of the worlds leading companies. Candidates will have the opportunity to work on highly technical topics related to some of Apples latest products in power 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 of the magnetic field in addition to thermal simulation and heat transfer. The candidate should have basic knowledge of the physics of magnetic materials Maxwells equations heat transfer theory 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. Duties include: - 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.- Statistical analysis of design perturbations- Participate in material selection through experimental/theoretical investigations working with external vendors and other cross-functional teams to find optimized solutions- Be a good communicator and demonstrate collaboration in a highly cross-functional environment
