Wireless RF PHY FW Engineer

Summary

Would you like to join Apple’s growing Wireless Connectivity Silicon team? Our wireless System on a Chip (SoC) organization is responsible for all aspects of wireless silicon development with a particular emphasis on highly energy efficient design and new technologies that transform the user experience at the product level. A world‑class, vertically integrated engineering team spans RF/Analog architecture and design, Systems/PHY/MAC architecture and design, VLSI/RTL design and integration, emulation, design verification, test and validation, and firmware/software engineering.

In this highly visible role you will be at the center of a silicon design group with a critical impact on delivering functional wireless products to hundreds of millions of customers. Your core responsibility is crafting and implementing embedded firmware for SoC bring‑up and wireless connectivity enablement, working closely with product software and manufacturing teams to enable RF and PHY calibrations, algorithms, and testing for productization of the silicon and system.

As an Embedded FW Engineer you will be a core member of a Wireless SoC firmware team, focusing on radio and PHY bring‑up, RF calibrations, signal processing algorithm implementation, and performance tuning.

• Work closely with product software and manufacturing teams to provide system‑level API and firmware functionality to meet productization needs; develop SoC test and calibration capabilities for wafer, module, and system factories.
• Collaborate with RF/Radio design, DVT, PHY and System engineering teams to architect, define, and implement innovative algorithms, calibrations and protocols.
• Debug realtime systems with limited visibility, working hands‑on with development boards and lab equipment.
• Support pre‑silicon validation efforts, including simulation, emulation, and FPGA prototyping.
• Support post‑silicon bringup, validation, performance characterization, system integration, and debug.

• Strong background in embedded firmware development using C and assembly languages, familiarity with ARM CPUs and their internals.
• Good understanding of embedded wireless communication systems, radio and PHY fundamentals, and key RF performance metrics.
• Familiarity with digital signal processing algorithms.
• Experience with low‑level hardware interfaces, register and interrupt programming, bare‑metal software development, clock and power management.
• Solid understanding of basic embedded concepts such as RTOS, concurrency, multi‑processor systems.
• Fluency in using lab equipment such as logic analyzers, oscilloscopes, network analyzers, spectrum analyzers, signal generators, and power meters.
• Experience implementing diagnostics, manufacturing tests, and protocol compliance software.
• Knowledgeable of industry standards for wireless communications such as Bluetooth, WLAN, Zigbee, or UWB.
• Proficient in at least one of the scripting languages such as Python, Perl, or Tcl.
• Excellent communication skills – both written and oral.
