Job Description

Do you have a passion for invention and self-challenge? Do you thrive on pushing the limits of what’s considered feasible? As part of an extraordinary modem team, you’ll craft sophisticated & pioneering embedded firmware that deliver more performance in our products than ever before. You’ll work across subject areas to transform improved hardware elements into a single, integrated 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.

Description

- Implement key 3GPP protocols and control/data path processing algorithms with very tight time, latency and energy budgets by interfacing to specialized cellular ASIC hardware.

- Examples of processing include 3GPP channels and procedures such as PDCCH, PDSCH, PBCH, PUCCH, PUSCH, PRACH, UL/DL HARQ, Tracking loops.

- 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 pioneering tools for build, formal verification and test.

- Define methodologies and best practices.
