Role Posting Log in to save

Sr. Wireless Firmware Engineer (Starlink Mobile) joins the Starlink Mobile program to provide global cellular connectivity from space. This role involves developing novel wireless signal processing algorithms, implementing optimized software for satellites and ground stations, and debugging complex performance issues across the physical and MAC layers. The engineer will design and implement 4G/5G LTE/NR eNodeB/gNodeB algorithms on resource-constrained CPUs while contributing to system dimensioning and architecture reviews. Key technical requirements include proficiency in C/C++, Python, Linux command line, and git-based version control. Candidates should possess expertise in digital signal processing, forward error correction coding, and software-defined radio. The work focuses on the technical challenges of satellite-based mobile broadband, specifically addressing physical layer development and solving interdisciplinary problems to ensure robust performance for non-terrestrial networks using OFDM waveforms like WiMAX or DVB-S2.

Skills

What you'll do

  • Design and implement physical layer (PHY) algorithms for satellite-based 4G/5G networks.
  • Develop optimized signal processing algorithms for use on resource-constrained CPUs.
  • Create models and run simulations to analyze and validate modem and system performance.
  • Design, implement, test, and document the wireless PHY and MAC layers of the protocol stack.
  • Identify and debug complex performance issues across the wireless PHY and MAC layers.
  • Contribute to architecture design, code reviews, and dimensioning for next-generation hardware.

What we're looking for

  • Bachelor's, Master's, or PhD degree in computer science, computer engineering, electrical engineering, or a STEM discipline.
  • 5+ years of experience in wireless signal processing, modem systems design, wireless systems engineering, DSP, or physical layer processing.
  • 5+ years of C/C++ coding experience.
  • Familiarity with 3GPP 4G/5G (LTE/NR) physical layer design or other modern broadband OFDM waveforms.
  • Experience in developing and optimizing complex signal processing algorithms in both fixed and floating point.
  • Familiarity with Linux command line, git-based version control, and Python programming.
  • Experience with software-defined radio (SDR) and supporting products through the full release cycle.
  • Must be a U.S. citizen, national, lawful permanent resident, or eligible for required export control authorizations.
