Embedded 5G/4G Cellular Physical Layer Firmware Engineer (m/f/d)
Do you have a passion for invention and self-challenge? Do you thrive with pushing the limits of what’s considered feasible? As part of an outstanding modem team, you’ll craft sophisticated groundbreaking embedded firmware that delivers 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.
You will collaborate 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. Do you want to have an impact on every single Apple product? As a Wireless Embedded Physical Layer 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 state-of-the-art cellular SoCs.
This position requires someone comfortable will all aspects of embedded software development, thrives in a sophisticated multi-functional organization, is not afraid to debate ideas openly, and is flexible enough to pivot on constantly evolving requirements.
- Specify, design, and implement the firmware architecture of a groundbreaking mobile wireless communications system.
- Implement key protocol, signal processing, and numerical algorithms with very tight time, latency, and energy budgets by collaborating with niche cellular ASIC hardware.
- Work with silicon designers to define a processor, bus, DMA, accelerator, and memory subsystems.
- 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 groundbreaking tools for build, formal verification, and testing.
- Define methodologies and best practices.
- Very good proficiency in C and/or C++, compilers, build, and source code control tools.
- Very good understanding of embedded software engineering principles, and core computer science fundamentals.
- Significant experience with memory-constrained Real-Time Operating Systems (RTOS) and concurrent programming.
- Validated experience in debugging embedded software systems. Familiarity with UARTs, JTAG, and oscilloscopes.
- Shown understanding of computer architecture with particular emphasis on the HW/SW interfaces of high-speed communication subsystems.
- English language proficiency is required for this position.
- Bachelor or Master in Computer Science, Embedded System Engineering, or Electrical/Information Engineering with extensive years of working experience or PhD in a relevant field with proven years of working experience.
- Experience with silicon prototyping, emulation systems, and virtual platforms.
- Some mainstream OS application-level development and Python or Perl scripting experience would be desirable
- Experience with hardware control for physical layer 4G/5G data path processing is a plus
- Understanding of 5G and 4G 3GPP protocols would be a nice-to-have
