DSP Firmware Engineer

Cupertino, CA
  • Job Code


Would you like to join Apple's growing wireless silicon development team? Our wireless SOC organization is responsible for all aspects of wireless silicon development with a particular emphasis on highly energy efficient design and new technologies that transform the user experience at the product level, all of which is driven by a world-class vertically integrated engineering team spanning RF/Analog architecture and design, Systems/PHY/MAC architecture and design, VLSI/RTL design and integration, Emulation, Design Verification, Test and Validation, and FW/SW engineering.

In this highly visible role, you will be at the center of a silicon design group with a critical impact on getting functional wireless products to hundreds of millions of customers quickly

Key Qualifications

  • You will have a minimum of 5 years of DSP firmware development as well as a strong background in DSP algorithms and embedded wireless systems
  • Strong background in embedded software development using C and assembly languages, familiarity with ARM CPUs
  • Experience writing optimized DSP routines for vector / SIMD processors
  • Experience with algorithms such as FFT, matrix operations, eigenvalue decomposition, SVD, MUSIC, or other complex linear algebra techniques
  • Experience with Matlab and Python
  • Familiarity with ARMv8 NEON architecture is desirable


As a DSP FW Engineer, the individual will be a core member of a Wireless SoC design team, with emphasis on deftly mapping PHY-layer algorithms to firmware, assisting with hardware and system bring-up, performance characterization and tuning, and support of other teams interacting within a Wireless SoC group working on advanced wireless protocols.
- Work closely with systems team to design and deftly implement DSP algorithms to meet constraints for latency, memory size, and power consumption
- Work well with SoC firmware and test teams to support bring up, lab characterization, and debug product level issues
- Implement DSP firmware to map high-level algorithms from Matlab/C to architecture-specific code, utilizing features such as SIMD, vector processing, assembly code, and caches
- Analyze system performance to identify areas for optimization and inform chip architectural designs such as core selection, hardware accelerators, or custom instruction sets
