About the role

Wireless Systems Engineer for Starlink Mobile responsible for designing and developing wireless communication algorithms to maximize system performance for the Starlink Mobile satellite constellation and future networks.

Responsibilities

  • Design and optimize wireless systems algorithms at the MAC and PHY layer for link adaptation, power control, timing advance, and doppler tracking.
  • Design and simulate complex MAC layer scheduling algorithms that support joint scheduling of users across multiple beams subject to Quality of Service (QoS) and latency constraints.
  • Analyze inter-cell and inter-beam interference on both uplink and downlink, identify issues on-orbit, and propose solutions through beam planning optimizations, MAC layer scheduling improvements, or advanced signal processing techniques.
  • Run link level simulations and system level simulations to compare performance of different algorithms at all layers of the protocol stack.
  • Work directly with software engineers to implement algorithms and deploy to orbit.
  • Qualify algorithm performance in production through aggregate KPI analysis, high rate per TTI telemetry, and UE log analysis.
  • Develop high-fidelity models for wireless systems in non-terrestrial applications that leverage 3GPP defined protocols (4G/5G/6G).

Qualifications

  • Bachelor’s degree in computer science, engineering, math, or STEM discipline and 1+ years of engineering experience (internship/project experience is acceptable); OR 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.
