Job description

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.
  • Develop high-fidelity models for wireless systems in non-terrestrial applications that leverage 3GPP defined protocols (4G/5G/6G). 
BASIC 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. 
PREFERRED SKILLS AND EXPERIENCE: 
  • Master's degree or PhD in wireless communication systems.
  • Experience with system design or implementation of MAC and PHY algorithms for cellular systems.
  • Prior experience debugging issues for a production wireless network deployed at scale.
  • Prior experience with link level simulations that characterize physical layer decode performance under different channel models.
  • Prior experience with system level simulation of a communication network modeling inter-cell and inter-user interference.
  • Fluent in MATLAB and working knowledge of python and/or C/C++.
  • Strong skills in debugging, performance optimization, and data analysis; exceptional analytical skills and engineering fundamentals.
  • Excellent verbal and written communication skills.
  • Ability to work effectively in a dynamic environment with changing needs and requirements. 
 ADDITIONAL REQUIREMENTS: 
  • Willing to work extended hours and weekends when needed
COMPENSATION AND BENEFITS:    
Pay range:    
Software Engineer/Level I: $135,000.00 - $155,000.00/per year    
Software Engineer/Level II: $155,000.00 - $185,000.00/per year    
   
Your actual level and base salary will be determined on a case-by-case basis and may vary based on the following considerations: job-related knowledge and skills, education, and experience.
Base salary is just one part of your total rewards package at SpaceX.
