TL;DR · Wireless RF PHY Firmware Engineer

The Wireless RF PHY Firmware Engineer joins the Wireless Connectivity Silicon team to develop embedded firmware for SoC bring up and wireless connectivity enablement. This role focuses on PHY bring up, RF calibrations, signal processing algorithm implementation, and performance tuning. The engineer will collaborate with product software and manufacturing teams to provide system-level APIs and test capabilities for wafer, module, and system factories. Key responsibilities include implementing algorithms on embedded CPUs, ensuring alignment with Python reference implementations, and debugging real-time systems using lab equipment like oscilloscopes and spectrum analyzers. Required skills include C, assembly, and Python, along with expertise in ARM CPUs, RTOS, multi-core environments, and digital signal processing. The role addresses the technical challenge of enabling time-critical, online calibrations and managing hardware interfaces for wireless standards such as Bluetooth, WLAN, ZigBee, and UWB.

What you'll do

  • Implement embedded firmware for SoC bring-up and wireless connectivity enablement.
  • Develop RF calibrations, signal processing algorithms, and performance tuning for wireless products.
  • Create system-level APIs and firmware functionality to support manufacturing and productization needs.
  • Translate Python reference implementations into optimized C code for embedded CPUs.
  • Integrate time-critical, online calibration routines into the firmware flow.
  • Debug real-time systems using development boards and lab equipment like oscilloscopes and logic analyzers.
  • Support pre-silicon validation through simulation, emulation, and FPGA prototyping.
  • Resolve issues related to corner cases, part-to-part variations, and error recovery mechanisms.

What we're looking for

  • Bachelor's degree in Electrical Engineering, Computer Engineering, or a related field.
  • Knowledge of embedded systems including multi-thread environments, interrupt processing, and resource management.
  • Experience in embedded firmware development using C and assembly languages with familiarity with ARM CPUs.
  • Understanding of wireless communication systems, Radio/PHY fundamentals, and digital signal processing algorithms.
  • Proficiency in scripting languages such as Python, Perl, or Tcl.
  • Ability to use lab equipment including logic analyzers, oscilloscopes, network analyzers, and spectrum analyzers.
  • Experience with low-level hardware interfaces, register programming, bare-metal development, and power management.
  • Knowledge of wireless industry standards such as Bluetooth, WLAN, ZigBee, or UWB.
