Do you have a passion for invention and self-challenge? As part of an extraordinary modem team, you'll craft sophisticated powerful embedded firmware that delivers more performance in our products than ever before We'll work across teams 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 an Embedded Firmware Engineer passionate about real-time critical control 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 firm development, who thrives in a multifaceted multi-functional organization, is not afraid to debate ideas openly, and is flexible enough to shift on constantly evolving requirements.Description Design interfaces and call flows for 3GPP control processing - Lead others toward control feature delivery and support - Design and Implement algorithms using minimal memory and cycles with rigid real-time deadlines Implement algorithms such as power gating, tracking loops, spec-based physical layer procedures - Build validation frameworks for the validation of implemented algorithms - 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 building, formal verification, and testingMinimum Qualifications Hands-on experience with the design and implementation of bare metal control firmware which is highly optimized for cycles and memoryDeep understanding of the difference between design for a software platform and a highly constrained firmware environmentHands-on experience with C and C++, compilers, build and source code control toolsProven understanding of computer architecture with particular emphasis on the HW/SW interfaces of high-speed communication subsystemsExperience with silicon prototyping, emulation systems, and virtual platformsProficiency in debugging embedded software systemsEnglish language proficiency is required for this positionPreferred Qualifications Bachelor or Master or higher degree (eg.
