Role Number:200239989

The Watch System EE Validation team is looking for a motivated engineer who wants to tackle RF system coex problems through data, measurements, and simulation. You are hands-on problem solver, a detailed and analytical thinker, have an aptitude for learning, and enjoy all manner of electromagnetics, antennas, and RF. You bring data-driven decision-making and analytics to improve our products.

You will apply simulation and modeling to unveil the 'hidden schematic' of system coexistence. What are the various ways a RF couples and affects a sensitive subsystem? Gain insight into complex issues impacting product design and architecture to deliver a world-class user experience for Apple Watch and its millions of users.

Are you oriented to details, a hands-on problem solver who enjoys acquiring and applying knowledge? If so, then this is an opportunity for you to be on our team.

Key Qualifications

  • You are a team collaborator with excellent interpersonal communication and documentation skills who can thrive in a multi-functional environment
  • We possess excellent RF and electrical engineering fundamentals
  • Experience with simulation software such as CST and HFSS, or equivalent
  • Familiar with RF test equipment
  • Experience integrating LTE/WiFi/BT/UWB antennas and radios into shipping designs
  • Experience with Python, MATLAB or similar scripting language for capturing and analyzing large datasets

Description

You will spend your time working multi-functionally to learn about sensor modules and antennas, gain insights into coex mechanisms, and collaborate on driving solutions. This effort will include data collection, data processing, RF/OTA measurements, and 3D electromagnetic modeling activities.
- Create full 3D electromagnetic simulation models of Apple Watch and its sub-systems
- Setup and perform RF conducted and radiated validation/correlation measurements on prototype hardware
- Be an integral part of the FA process for RF coex, driving proper measurement methodologies, and proposing experiments
- Explore impact of antenna design on systems, propose and run simulations to identify where and how RF energy is coupled
- Apply insights to influence design decisions for SIP, flex, sensor modules, and other subsystems
- Explore various sensor modules, their physics of operation, and susceptibility to RF
- Light-duty scripting and automation to collect data from prototype hardware
- Data analysis of system coex data, antenna data, and other applicable data for modeling and FA

NICE TO HAVE
- Experience with high speed layout
- Familiar with EMC and EMI measurements
- Familiar with chip-level I/O designs, and analog-front ends
- Experience with sampled systems and digital signal processing
- Familiar with material electrical properties characterization
- Embedded system design experience

Education & Experience

A BS or MS degree in Electrical Engineering, preferably with a focus in RF and antennas.
