Wireless Systems Engineer (Starlink Mobile)

Sunnyvale, CA

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.
  • 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. You may also be eligible for long-term incentives, in the form of company stock, stock options, or long-term cash awards, as well as potential discretionary bonuses and the ability to purchase additional stock at a discount through an Employee Stock Purchase Plan. You will also receive access to comprehensive medical, vision, and dental coverage, access to a 401(k)-retirement plan, short and long-term disability insurance, life insurance, paid parental leave, and various other discounts and perks. You may also accrue 3 weeks of paid vacation and will be eligible for 10 or more paid holidays per year. Employees accrue paid sick leave pursuant to Company policy which satisfies or exceeds the accrual, carryover, and use requirements of the law.

Race & Ethnicity Definitions

If you believe you belong to any of the categories of protected veterans listed below, please indicate by making the appropriate selection. As a government contractor subject to the Vietnam Era Veterans Readjustment Assistance Act (VEVRAA), we request this information in order to measure the effectiveness of the outreach and positive recruitment efforts we undertake pursuant to VEVRAA. Classification of protected categories is as follows:

A "disabled veteran" is one of the following: a veteran of the U.S. military, ground, naval or air service who is entitled to compensation (or who but for the receipt of military retired pay would be entitled to compensation) under laws administered by the Secretary of Veterans Affairs; or a person who was discharged or released from active duty because of a service-connected disability.

A "recently separated veteran" means any veteran during the three-year period beginning on the date of such veteran's discharge or release from active duty in the U.S. military, ground, naval, or air service.

An "active duty wartime or campaign badge veteran" means a veteran who served on active duty in the U.S. military, ground, naval or air service during a war, or in a campaign or expedition for which a campaign badge has been authorized under the laws administered by the Department of Defense.

An "Armed forces service medal veteran" means a veteran who, while serving on active duty in the U.S. military, ground, naval or air service, participated in a United States military operation for which an Armed Forces service medal was awarded pursuant to Executive Order 12985.

Voluntary Self-Identification of Disability

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005
Expires 04/30/2026

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
