Role Posting Log in to save

Sr. Wireless Firmware Engineer (Starlink Mobile) joins the Starlink Mobile program to provide global cellular connectivity from space. Working alongside wireless systems and protocol firmware engineers, this role focuses on accelerating wireless PHY development and solving interdisciplinary challenges. The engineer will design and implement physical layer algorithms for satellite-based 4G/5G LTE/NR eNodeB/gNodeB, develop optimized signal processing for resource-constrained CPUs, and manage the MAC layers of the protocol stack. Key responsibilities include building models to validate modem performance, debugging complex system issues, and contributing to hardware dimensioning. Required expertise includes C/C++ coding, digital signal processing, and experience with 3GPP standards or OFDM waveforms like WiMAX and DVB-S2. The role also utilizes Python, Linux command line tools, git version control, and software defined radio technology to solve complex problems in the satellite communications domain.

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 forward error correction (FEC) coding concepts and MAC layer basics.
Proficiency with Linux command line, git-based version control, and Python programming.
Must be a U.S. citizen, national, lawful permanent resident, or eligible for required export control authorizations.
