Form of workSummary
Do you have a passion for invention and self-challenge? As part of an extraordinary modem team, you'll craft sophisticated innovative embedded firmware that deliver more performance in our products than ever before! We'll work across subject areas to transform improved hardware elements into a single, coordinated design. Join us, and you'll help us innovate new wireless systems technologies that continually outperform the previous iterations. By collaborating with other product development groups across Apple, you'll push the industry boundaries of what wireless systems can do and improve the product experience for our customers across the world. As a Wireless Embedded Physical Layer DSP Firmware Engineer on this team, 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. This position requires someone comfortable will all aspects of embedded software development, that thrives in a multifaceted multi-functional organization, is not afraid to debate ideas openly, and is flexible enough to shift on constantly evolving requirements.
Key Qualifications
Minimum BS and 10+ years of relevant industry experience.
Experience implementing digital signal processing algorithms using special purpose digital signal processing HW
Understanding of 5G and 4G 3GPP protocols
Deep understanding of software engineering principles, and core computer science fundamentals
Fundamental facility with C and C++, compilers, build and source code control tools
Significant experience with memory constrained Real Time Operating Systems (RTOS) and concurrent programming
Proven understanding of computer architecture with particular emphasis on the HW/SW interfaces of high speed communication subsystems
Experience with silicon prototyping, emulation systems, and virtual platforms
Proficiency debugging embedded software systems. Familiarity with UARTs, JTAG, and oscilloscopes
Some mainstream OS application level development and Python or Perl scripting experience
Description
• Design interfaces and call flows for DSP processing
• Lead others toward DSP feature delivery and support
• Implement key 3GPP digital signal processing algorithms with very tight time, latency and energy budgets by interfacing to niche cellular ASIC hardware. Examples of 3GPP algorithmic areas include:
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
Work with silicon designers to define HW interfaces, processors, bus, DMA, accelerator, and memory subsystems
Specify, design, and implement the firmware architecture of an innovative mobile wireless communications system
Assist in the development of pre-silicon emulation systems/virtual platforms and use them for pre-silicon FW design and HW verification
Evaluate and implement powerful tools for build, formal verification and test
Define methodologies and standard processes
Education & Experience
Minimum BS and 10+ years of relevant industry experience.
