About the role

Embedded Firmware Engineer focused on real-time critical control within a silicon design group responsible for crafting and productizing cellular SoCs. Role involves designing and implementing optimized firmware, developing validation and pre-silicon systems, and leveraging AI/ML for productivity while meeting tight real-time constraints across 4G/5G/multimode cellular firmware.

Responsibilities

  • Implement algorithms such as power gating, tracking loops, spec based physical layer procedures.
  • Build validation framework for 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 build, formal verification and test.

Qualifications

  • BS and a minimum of 10 years relevant industry experience.
  • Experience with 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.
  • Experience leading feature delivery for a complete firmware/software life cycle.
  • Experience architecting system level features.
  • Fundamental facility with C and C++, compilers, build and source code control tools.
  • Solid understanding of computer architecture with particular emphasis on the HW/SW interfaces of high-speed communication subsystems.
  • Some mainstream OS application-level development and Python or Perl scripting experience.
  • Strong foundation in Machine Learning and Deep Learning: Experience with ML algorithms and deep learning architectures (e.g., CNNs, RNNs, Transformers).
  • Experience using generative AI as a tool for design and implementation.
  • Theoretical understanding of the implementation of AI/ML Algorithms: In-depth knowledge of the mathematical foundations of various AI/ML algorithms and how to apply to parameter estimation algorithms.
  • Understanding of HW architectures and programming models for how to target algorithms to AIML acceleration HW.
  • 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.
