Wireless Firmware Engineer; Direct To Cell

Overview

Wireless Firmware Engineer (Direct To Cell)  direct-to-cell program aims to provide global cellular connectivity from space. This role focuses on developing novel wireless signal processing algorithms, implementing optimized software for satellites and ground stations, debugging complex systems, and producing production software. The candidate should be comfortable with wireless signal processing and high-performance software development.

• Design and implement physical layer (PHY) algorithms for satellite-based 4G/5G (LTE/) eNodeB/gNodeB.
• Develop optimized signal processing algorithms for resource-constrained CPUs.
• Develop models and run simulations to analyze and validate overall system performance, including modem performance.
• Design, implement, test, maintain, 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.
• Participate in architecture, design, and code reviews. Contribute to system dimensioning and algorithm design for next generation hardware.

• Bachelor's, Master’s or PhD degree in computer science, computer engineering, electrical engineering or a STEM discipline.
• 1+ years of experience with at least one of the following: wireless signal processing, wireless communications, modem systems design, wireless systems engineering, DSP, or physical layer processing (L1).
• 1+ years of C/C++ or Matlab coding experience.

• Familiarity with 3
  
  GPP 4G/5G physical layer design or other modern broadband OFDM waveforms.
• Familiarity with forward error correction (FEC) coding concepts.
• Basic familiarity with MAC layer (L2).
• Development and optimization of complex signal processing algorithms in fixed and floating point.
• Familiarity with Linux command line, git, and Python.
• SDR (software defined radio) experience.
• Experience supporting products through full release cycle including commercial deployment.
• Strong debugging and performance optimization skills; solid engineering fundamentals.
• Excellent verbal and written communication skills.
• Ability to work effectively in a dynamic environment with changing needs and requirements.

• Must be willing to work extended hours and weekends as needed.
