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