Embedded 5G/4G Cellular Physical Layer Data Path Signal Processing Firmware Engineer
Sunnyvale, California, United States
Hardware
Apple is where individual imaginations gather together, committing to the values that lead to great work. Every new product we build, service we create, or Apple Store experience we deliver is the result of us making each other’s ideas stronger. It’s the diversity of our people and their thinking that inspires the innovation that runs through everything we do. As a Wireless Embedded Physical Layer Data Path Signal Processing Firmware Engineer, you will be at the center of the embedded 5G/4G/multimode cellular firmware effort within a silicon design group responsible for crafting and productizing powerful cellular SoCs.
Description
Implement key 3GPP digital signal processing algorithms with very tight time, latency and energy budgets by interfacing to specialized cellular ASIC hardware.
Implement firmware which implements 3GPP channels and procedures such as: PDCCH, PDSCH, PBCH, PUCCH, PUSCH, PRACH, UL/DL HARQ.
Implement Channel Estimation, Channel State Feedback, Interference Cancellation, Cell Search and Measurement, Beam Measurement.
Work with systems engineers to refine signal processing algorithms for efficient firmware/hardware execution.
Specify, design, and implement the firmware architecture for superior power, performance, and cost.
Assist in the development of pre-silicon emulation systems/virtual platforms and use them for verification.
Evaluate and implement groundbreaking tools for build, formal verification and test.
Define methodologies and standard processes.
Minimum Qualifications
BS and 10+ years of relevant industry experience.
Experience implementing digital signal processing algorithms using special purpose digital signal processing HW -OR- wireless physical layer channels by interfacing to special purpose hardware.
Experience leading feature delivery for a complete firmware/software life cycle.
Experience architecting system level features.
Deep understanding of software engineering principles, and core computer science fundamentals.
Fundamental facility with C and C++, compilers, build and source code control tools.
Experience with silicon prototyping, emulation systems, and virtual platforms.
Solid understanding of computer architecture with particular emphasis on the HW/SW interfaces of high-speed communication subsystems.
Some mainstream OS application-level development and Python or Perl scripting experience.
Key Qualifications
Understanding of 5G and 4G 3GPP protocols.
Some familiarity with wireless communications.
Significant experience with memory constrained Real Time Operating Systems (RTOS) and concurrent programming.
Pay & Benefits
At Apple, base pay is one part of our total compensation package and is determined within a range. The base pay range for this role is between $175,800 and $312,200, depending on your skills, qualifications, experience, and location.
