Role Number:
200515345 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 a validation framework for the validation and verification 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 build, formal verification, and test
Key Qualifications - Experience with the design and implementation of bare metal control firmware which is highly optimized for cycles and memory
- Deep understanding of the difference between design for a software platform and a highly constrained firmware environment
- Understanding of the use of data structures for deterministic and efficient reads and writes
- Understanding of design for asymmetric multiprocessing solutions
- Fundamental facility with C and C++, compilers, build and source code control tools
- Proven understanding 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
- Understanding of 5G and 4G 3GPP protocols is required
- Familiarity with wireless communications is a plus
English language proficiency is a requirement for this position.
Education & Experience A bachelor’s or master's degree in electrical engineering, computer science or embedded systems as well as a minimum of 5 years of work experience are required for this position.
