TL;DR · Modem Firmware Engineer

JOB TITLE: Modem Firmware Engineer As a Modem Firmware Engineer within the Cellular Technologies Software group, you will join the proprietary vector DSP FW development team. You will design, standardize, and implement state-of-the-art cellular technologies, specifically contributing to PHY layer modem firmware. Your daily responsibilities include programming low-level ASM type optimized SIMD instruction sets, performing modem signal processing for Tx and Rx baseband chains, and managing modem control software orchestration within constrained MIPS and memory environments. You will utilize C, Python, and DSP Intrinsics/ASM to develop high-performance air interfaces. Key tasks involve test-driven development, designing for test, and implementing AI/ML native modem enhancements. You will also work on ORAN and FAPI specifications, ensuring that the modem meets rigorous industry standards for capacity, coverage, throughput, and latency.

What you'll do

  • Design, implement, and validate state-of-the-art cellular technologies and air interfaces.
  • Develop PHY layer modem firmware using proprietary DSP low-level ASM and SIMD instructions.
  • Program modem signal processing for Tx and Rx baseband chains.
  • Orchestrate modem control software and embedded firmware within constrained MIPS and memory environments.
  • Develop efficient test methodologies and unit test cases for modem DSP firmware integration.
  • Implement AI/ML native modem enhancements and design for test.
  • Write technical documentation and feature descriptions to guide user implementation.
  • Contribute to ORAN and FAPI specifications.

What we're looking for

  • Bachelor's degree in Computer Science, Electrical Engineering, or a related field.
  • Proficiency in DSP Intrinsics/ASM, C, Python, Real-time operating systems, and Embedded systems.
  • Skills in SIMD optimization, Signal Processing/Communication theory, and multi-threaded programming.
  • Master's degree in Computer Science, Computer Engineering, Electrical Engineering, or a related field (preferred).
  • 1+ year of applicable wireless, semiconductor, and/or embedded software industry experience (preferred).
  • 1+ year of experience with computer architecture or embedded systems (preferred).
  • Experience with DSP development, Matlab, Modem/PHY layer FW development, and 5G NR/LTE protocols (preferred).
