Summary
At Apple, we work every single day to craft products that enrich people's lives. Do you love working on challenges that no one has solved yet? Do you like changing the game? As a Wireless RF OTA UWB Systems Engineer, you will be a core member of our highly innovative and visible wireless system team with the unique and rewarding opportunity to shape upcoming products that will delight and inspire millions of Apple's customers every day.
One emphasis of your specific role will be end-to-end modeling and simulation of sophisticated wireless systems, including but not limited to radio propagation channel, RF/antenna, PHY/MAC, and sensor fusion schemes.

Key Qualifications
Expertise in wireless communication, antenna theory, microwave engineering, and radio propagation modeling/simulation.
Experience with end-to-end wireless system modeling, simulation, and performance analysis (link budget) with various user behaviors. Corresponding SW programming proficiency with Matlab/Python required.
Extensive hands-on EM simulation skills on FEM, FDTD, SBR+, and ray-tracing simulation tools.
Experience with handling and processing large amounts of field and simulation data, including user-friendly visualization of complex test setups and simulation results.
Working experience with different lab equipment: network analyzers, signal generators, signal analyzers, channel emulators, etc.
Some familiarity with common RF impairments encountered in wireless systems.
Expertise and proven record in wireless channel sounding and modeling is a plus.
Experience with and/or knowledge of UWB/BLE/GPS industry standards and regulatory requirements is a plus.
Excellent communication skills required, both written & verbal, including creating high-quality slides.

Description
You will work closely with antenna engineers, PHY systems and algorithm engineers, FW and SW engineers in the areas above.
In order to perform end-to-end wireless system performance analysis, you need to collaborate with multi-functional teams to model, simulate, and visualize the performance of complex sub-system blocks from user movement, wireless propagation models, and RF/antenna behavior, via PHY/MAC protocols and associated signal processing mechanisms, all the way to simulating sensor fusion processing.
You will build an end-to-end simulator using Matlab/Python to predict system performance at various wireless channel conditions.
You will design validation methods to correlate modeling results with measured data. In this process, you will need to identify critical root-causes of the discrepancy and improve the system modeling accordingly.
You will present the results and important findings to cross-functional teams and senior leadership.

Education & Experience
BS degree in technical discipline with minimum 3 years of relevant experience.
