Wireless RF PHY FW Engineer

About the role

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

Responsibilities

• Work closely with product SW 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.

Requirements

• Strong background in embedded FW development using C and assembly languages, familiarity with ARM CPUs and its 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, 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.
• Minimum requirement of a bachelors degree.
• Pay & Benefits
• Note: Apple benefit, compensation and employee stock programs are subject to eligibility requirements and other terms of the applicable plan or program.
