{"title": "Embedded 5G/4G Cellular Physical Layer Firmware Engineer (m/f/d)", "summary": "Do you have a passion for invention and self-challenge?  Do you thrive on pushing the limits of what\u2019s considered feasible? As part of a world-class modem team, you\u2019ll craft sophisticated leading-edge embedded firmware that delivers more performance in our products than ever before. You\u2019ll work across disciplines to transform improved hardware elements into a single, integrated design. Join us, and you\u2019ll help us innovate new wireless systems technologies that continually outperform the previous iterations. By collaborating with other product development groups across Apple, you\u2019ll 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 designing and productizing state-of-the-art cellular SoCs. This position requires someone comfortable will all aspects of embedded software development, thrive in a dynamic cross-functional organization, is not afraid to debate ideas openly, and is flexible enough to pivot on constantly evolving requirements.", "description": "Specify, design, and implement the firmware architecture of a state-of-the-art mobile wireless communications system. Implement key protocol, signal processing and numerical algorithms with very tight time, latency, and energy budgets by interfacing to specialized 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 leading-edge tools for build, formal verification, and testing. Define methodologies and best practices.", "key_qualifications": "Experience with hardware control for physical layer 4G/5G data path processing. Understanding of 5G and 4G 3GPP protocols would be a nice-to-have. Very good understanding of software engineering principles, and core computer science fundamentals. You have a solid proficiency in C and C++, compilers, build, and source code control tools. Experience with memory-constrained Real-Time Operating Systems (RTOS) and concurrent programming. Working knowledge 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 in debugging embedded software systems. Familiarity with UARTs, JTAG, and oscilloscopes. Some mainstream OS application level development and Python or Perl scripting experience. English language proficiency is required for this position", "preferred_qualifications": "", "education_experience": "Bachelor\u2019s or Master's degree in electrical engineering or computer science is required.
