Job summary

SpaceX in Sunnyvale is seeking a Wireless Systems Engineer (Starlink Mobile) to design and optimize MAC/PHY wireless algorithms and to deploy production-ready solutions for a global satellite network.

The ideal candidate brings deep knowledge of 3GPP protocols, system-level simulation experience, and strong MATLAB/Python/C++ skills to build scalable, high-performance radio software for space-based networks.

Qualifications

• Bachelor’s degree in computer science, engineering, math, or STEM 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.

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 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).
