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.


SpaceX is looking for engineers with a hybrid background in both GNC (guidance, navigation, and control) and software development to join the Starlink Collision Avoidance team.

Starlink operates the world's largest satellite constellation — nearly half of the world's active satellites. Unlike legacy satellite operations which rely heavily on hands-on, human-in-the-loop operations, Starlink is designed from the ground up with autonomy in mind - "algorithms, not operators".

To ensure the safe operation of thousands of satellites, Starlink vehicles are equipped with advanced algorithms that enable them to remain aware of their surroundings and autonomously plan and execute collision avoidance maneuvers if they predict a high-risk close approach.

This team is responsible for "full-stack" ownership of the automated collision avoidance pipeline, involving the development of satellite-side algorithms, ground-side supporting services, as well as infrastructure for monitoring the performance of the system on orbit. This team is also responsible for the design and implementation of algorithms for generating high-accuracy future state predictions of Starlink satellites, for informing collision avoidance actions. Team members are also expected to have strong analytical backgrounds, with the ability to analyze and interpret production data or simulations to support feature validation and inform future development. No other team at any company has as much influence on space safety. If you are really excited about joining our team, it is more important to be motivated and to be able to learn quickly than it is to check every box. If you're less experienced, we'll pair you up with an excellent mentor to help you make improvements as fast as possible. If you're more experienced, we'll look forward to you jumping right in and helping us improve space safety.


  • Design and implement autonomous on-satellite collision avoidance algorithms using C++.
  • Design and implement ground services necessary to facilitate fully automated maneuver scheduling decisions using C++ and Python.
  • Design and implement tools and dashboards for monitoring the performance of the autonomous collision avoidance system.
  • Design and implement orbit determination systems, including state/uncertainty propagation for accurate orbit prediction.
  • Run Monte Carlo analysis to characterize the performance of new features.
  • Bulk data analysis of telemetry from thousands of satellites and dozens of ground services to precisely characterize system performance and identify future improvements.
  • Write integrated test cases for satellite and ground software.
  • Write high-quality documentation for implemented software and tooling.
  • Monitor on-orbit system performance, troubleshooting if necessary.
  • Coordinate with third-party data providers and constellation operators.
  • Incorporate into the on-call rotation and command satellites when manual intervention is necessary


  • Bachelor's degree in software, engineering, physics, or a related field.
  • Software development experience in either C++ or Python.


  • Master's degree in software, engineering, physics, or a related field.
  • 2+ years of experience in a space mission design or related role.
  • Strong understanding of some or all of the following areas: orbital mechanics, modeling and simulation, software development, statistics, and systems engineering.
  • Familiarity with state estimation and Kalman filtering, ideally with exposure to orbit determination applications.
  • Familiarity with the physics of the orbital debris and micrometeorite environment.
  • Familiarity with numerical probability of collision methods such as Alfano, Foster, and Hall.
  • Familiarity with micrometeoroid and orbital debris analysis techniques for assessing on-orbit risk.
  • Practical experience flying spacecraft.
  • Capable of identifying and solving complex problems with little to no supervision or direction.
  • Ability to work in a fast-paced, autonomously driven, and demanding atmosphere.
  • Examples of high-quality writing or software documentation on past projects


  • Must be willing to work extended hours and weekends as needed.

Pay range:    
GNC Engineer/Level I: $120,000.00 - $145,000.00/per year    
GNC Engineer/Level II: $140,000.00 - $170,000.00/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 & long-term disability insurance, life insurance, paid parental leave, and various other discounts and perks. You may also accrue 3 weeks of paid vacation & will be eligible for 10 or more paid holidays per year. Exempt employees are eligible for 5 days of sick leave per y

Voluntary Self-Identification

For government reporting purposes, we ask candidates to respond to the below self-identification survey. Completion of the form is entirely voluntary. Whatever your decision, it will not be considered in the hiring process or thereafter. Any information that you do provide will be recorded and maintained in a confidential file.

As set forth in SpaceX’s Equal Employment Opportunity policy, we do not discriminate on the basis of any protected group status under any applicable 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.

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
