Job Description

As an Embedded Firmware Engineer at Apple, you will be part of a team responsible for crafting and productizing powerful cellular SoCs. This role requires someone comfortable with all aspects of embedded firmware 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.

Key Responsibilities
  • Design and implement algorithms using minimal memory and cycles with rigid real-time deadlines.
  • Implement algorithms such as power gating, tracking loops, and spec-based physical layer procedures.
  • Build validation frameworks for validation of implemented algorithms.
  • Assist in the development of pre-silicon emulation systems and virtual platforms for pre-silicon FW design and HW verification.
  • Evaluate and implement powerful tools for build, formal verification, and test.
Requirements
  • BS and 3+ years of relevant industry experience.
  • Experience with design and implementation of bare metal control firmware highly optimized for cycles and memory.
  • Deep understanding of the difference between design for a software platform and a highly constrained firmware environment.
  • Fundamental facility with C and C++, compilers, build, and source code control tools.
  • Solid understanding of computer architecture with particular emphasis on HW/SW interfaces of high-speed communication subsystems.
  • Some mainstream OS application-level development and Python or Perl scripting experience.
Preferred Qualifications
  • Understanding of design for asymmetric multiprocessing solutions.
  • Understanding of 5G and 4G 3GPP protocols.
  • Some familiarity with wireless communications.
  • Experience with silicon prototyping, emulation systems, and virtual platforms.
  • Significant experience with memory-constrained Real-Time Operating Systems (RTOS) and concurrent programming.
