TL;DR · Wireless Systems Engineer

As a Wireless Systems Engineer (Starlink Mobile), you will join the team responsible for designing and developing wireless communications algorithms to maximize performance for the Starlink Mobile satellite constellation and future networks. You will design and optimize MAC and PHY layer algorithms for link adaptation, power control, timing advance, and doppler tracking. Your daily work involves simulating complex MAC layer scheduling, analyzing inter-cell and inter-beam interference, and developing high-fidelity models for non-terrestrial applications. You will collaborate with software engineers to implement and deploy production algorithms to orbit while qualifying performance through KPI analysis and telemetry. The role requires expertise in 3GPP RAN protocols (4G/5G/6G), MATLAB, Python, and C/C++. You will solve technical problems regarding signal processing and beam planning within a satellite communication framework.

What you'll do

  • Design and optimize MAC and PHY layer algorithms for link adaptation, power control, and Doppler tracking.
  • Design and simulate complex MAC layer scheduling algorithms to support joint scheduling across multiple beams.
  • Analyze inter-cell and inter-beam interference to propose solutions via beam planning or signal processing.
  • Run link-level and system-level simulations to compare performance across different protocol stack layers.
  • Work with software engineers to implement algorithms and deploy them to orbit.
  • Qualify algorithm performance in production using KPI analysis, telemetry, and UE log analysis.
  • Develop high-fidelity models for non-terrestrial wireless systems using 3GPP protocols.

What we're looking for

  • Bachelor’s degree in computer science, engineering, math, or STEM discipline and 1+ years of engineering experience.
  • 5+ years of professional engineering experience in lieu of a degree.
  • Experience with MAC and PHY layer protocols and algorithms used in cellular base stations.
  • Experience working with 3GPP protocols.
  • Master's degree or PhD in wireless communication systems (preferred).
  • Experience with system design or implementation of MAC and PHY algorithms for cellular systems (preferred).
  • Fluent in MATLAB and working knowledge of python and/or C/C++ (preferred).
  • Must be a U.S. citizen, national, lawful permanent resident, refugee, asylee, or eligible for Department of State authorization.
