Summary

Posted:
Role Number:200458366
As a Wireless PHY Systems & Simulation Engineer, you will be a core member of our highly innovative and visible Wireless System-on-Chip (SoC) design team! What does that mean? You will help define modem architectures, develope physical-layer algorithms, and invent embedded DSP algorithms for chips enabling exciting new wireless applications! One emphasis of your specific role will be end-to-end simulation of sophisticated systems, modeling components from a multitude of signal processing fields. Including but not limited to propagation channel modeling, RF/antenna abstractions, PHY & MAC protocols and algorithms, and sensor fusion schemes to fuse wireless and non-wireless metrics. Application areas include ultra-wideband sensing and specialized wireless audio; products enabled or enhanced by our team’s SoC’s include specialized audio headsets (such as AirPods) and iPhones.

Description

You will work closely with other PHY systems and algorithm engineers, analog and digital designers, FW & SW Engineers in the areas above. In order to invent/derive, simulate, implement, verify and test physical layer features, to make new chips and enable a variety of novel applications in the portable & wearable consumer electronics space. As well as collaborate with multi-functional teams to model, simulate, and visualize the performance of complex systems from user movement, wireless propagation models, and RF/antenna behavior, via PHY/MAC protocols and associated signal processing mechanisms, all the way to simulating inertial sensor fusion processing.

Minimum Qualifications

Key Qualifications

  • Expertise in Digital Signal Processing, Wireless Communications and wireless chip development.
  • Proven grasp of complex wireless systems with strong capability to comprehend dependencies between system components and protocol layers and their interactions.
  • Extensive hands-on SW programming skills for modeling and simulation of sophisticated systems from RF/PHY layer signals and channel modeling. All the way to MAC protocol/networking simulations; corresponding proficiency with Matlab/C/C++ required.
  • Experience with fixed-point design and RTL vector generation. HLS experience is a plus.
  • Experience with handling and processing large amounts of field and simulation data, including user-friendly visualization of complex test setups and simulation results, including measurement accuracies, system latencies, etc.
  • Some familiarity with common analog/RF impairments encountered in wireless systems.
  • Experience with and/or knowledge of industry standards such as Bluetooth, Ultra-Wideband, GPS, and/or other wireless protocols.
  • Experience in lab FPGA/silicon bring-up, PHY/RF/MAC testing and debugging and usage of lab equipment.
  • Some experience in IMU and/or camera/image signal processing, and/or some prior engagements in standards organizations or industry consortia are strong pluses.
