Wireless Systems Engineer (Starlink Mobile)

SpaceX was founded under the belief that a future where humanity is out exploring the stars is fundamentally more exciting than one where we are not. Today SpaceX is actively developing the technologies to make this possible, with the ultimate goal of enabling human life on Mars.

WIRELESS SYSTEMS ENGINEER (STARLINK MOBILE)

As a Wireless Systems Engineer for Starlink Mobile you will design and develop wireless communications algorithms that maximize system performance for the Starlink Mobile satellite constellation and future networks. The ideal candidate will have deep technical expertise in wireless communication systems, strong knowledge of 3GPP RAN protocols (4G/5G/6G), and an interest in building production algorithms that get deployed at global scale.

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.
