Wireless Firmware Engineer (Starlink Mobile) joins the Starlink Mobile program to provide global cellular connectivity from space. In this role, you will develop novel wireless signal processing algorithms and implement optimized software for satellites and ground stations. You will design and implement physical layer algorithms for satellite-based 4G/5G LTE/NR eNodeB/gNodeB, develop models to analyze modem performance, and debug complex issues across the wireless PHY and MAC layers. The position requires proficiency in C/C++ coding, digital signal processing, and wireless communications. Preferred skills include familiarity with 3GPP 4G/5G, forward error correction, Linux command line, git, and python programming. You will solve interdisciplinary challenges by bridging wireless signal processing and high-performance software development to accelerate wireless PHY development for non-terrestrial networks.
Design and implement physical layer algorithms for satellite-based 4G/5G LTE/NR eNodeB/gNodeB.
Develop optimized signal processing algorithms for use on resource-constrained CPUs.
Create models and run simulations to validate modem and overall 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 system dimensioning and algorithm design for next-generation hardware.
Participate in architecture, design, and code reviews.
What we're looking for
Bachelor's degree in computer science, computer engineering, electrical engineering, or a STEM discipline.
1+ years of experience in wireless signal processing, wireless communications, modem systems design, wireless systems engineering, DSP, or physical layer processing.
1+ years of C/C++ coding experience.
Familiarity with 3GPP 4G/5G (LTE/NR) physical layer design or other modern broadband OFDM waveforms (preferred).
Familiarity with forward error correction (FEC) coding concepts (preferred).
Basic familiarity with MAC layer (medium access control, L2) (preferred).
Familiarity with Linux command line, git-based version control, and python programming (preferred).
Must be a U.S. citizen, national, lawful permanent resident, refugee, asylee, or eligible for required Department of State authorizations.
