At Apple, creative thinking and thoughtful insights quickly transform into extraordinary products. Our successes are the result of highly skilled teams working in an environment that nurtures creativity, partnership and growth to produce novel solutions to tough problems. As a firmware engineer in the Wireless Connectivity Silicon Team, you will be responsible for the design, development, and bringup of innovative, fresh wireless silicon for various Apple products - the iPhone, Mac and more! New challenges arise every day that require the sharp problem-solving skills of passionate individuals dedicated to excellence. Are you ready to take on this challenge?We are looking for talented, creative and principled engineers who are well-versed with low-level embedded firmware and especially wireless PHY-layer firmware architecture and design- calibration algorithms, noise/interference processing, realtime processing flows, interfacing with RF hardware, power management/optimization, microcode, and/or MAC layer knowledge. You will be involved in the entire silicon production life-cycle, from pre-silicon validation using simulation, emulation, and FPGA prototyping to post-silicon bringup, performance characterization, system integration and debug, and finally to developing SoC test and calibration capabilities for chip, module, and product factories, after which you will see your hard work come to life in products used and loved by millions of people around the world. Engage in a dynamic, highly collaborative environment, and a play a significant part of the development of new silicon for Apple eco-systems by joining a best-in-class team responsible for: * Design and development of efficient solutions to deliver extraordinary performance with minimal power and memory footprints, all while under hard-realtime latency constraints * Debugging real-time systems with limited visibility, working hands-on with development boards and lab equipment * Collaboration with Radio, MAC, and Systems engineering teams to architect, define and implement innovative algorithms, calibrations, and protocols * Support of pre and post-silicon validation, bringup, and performance characterization * Develop SoC test and calibration capabilities for chip, module, and product factoriesHands-on experience and solid understanding of wireless systems and protocols such as LTE/NR/WiFi/Bluetooth Excellent problem-solving skills to address technical issues during design, development and maintenance phases Strong embedded SW fundamentals, including knowledge of design and development-flows, real-time constraints, concurrency, multi-processor systems, caching and virtual memory. Deep understanding of data structures, object-oriented design, and system architecture in an embedded environment Strong software engineering skills including design, development (using C, C++), scripting (Python), and debugging Familiarity with low-level hardware interfaces, register and interrupt programming, bare-metal software development, clock and power management. Experience with configuration (GIT, Perforce) and release management, continuous integration, unit and regression testing. Strong understanding of design strategies for maintainability, scalability, and code reuse. Excellent communication skills - both written and oral. Highly organized, motivated and passionate about driving resultsArray
