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.


At SpaceX we’re leveraging our experience in building rockets and spacecraft to deploy Starlink, the world’s most advanced broadband internet system. Starlink is the world’s largest satellite constellation and is providing fast, reliable internet to 2M+ users worldwide. We design, build, test, and operate all parts of the system – thousands of satellites, consumer receivers that allow users to connect within minutes of unboxing, and the software that brings it all together. We’ve only begun to scratch the surface of Starlink’s potential global impact and are looking for best-in-class engineers to help maximize Starlink’s utility for communities and businesses around the globe.

As an engineer on this team, you will bring a passion and expertise in areas like control theory, state estimation, orbital mechanics, spacecraft systems design, optimization, and software development to join the Starlink guidance, navigation, and control (GNC). Come help us write the autopilot algorithms for thousands of satellites (the world's largest constellation!) and more than one million user terminals, enabling access to high speed broadband internet in all corners of the world.


  • Design and analysis of GNC logic for consumer and enterprise Starlink phased array antennas.
    • Real-time angular and translational navigation using onboard sensors and optimal state estimation techniques.
    • Design of beam-steering logic to track and hand-off satellites while maximizing link integrity in challenging operational environments.
  • Develop features which will enable Starlink to be deployed in a variety of new applications, including ships, aircraft, spacecraft, and more.
  • Provide engineering and data review support for hardware development, special projects, and customer support triage.
  • Work with hardware engineers on the design and specification of future user terminal products and their navigation sensor packages.
  • Model derivation and high fidelity simulation for development and validation of prototype features.
  • Implementation, validation, unit testing, and deployment of production software (C++) pertinent to the systems described above.


  • Bachelor's degree in aerospace, physics, or an engineering discipline.
  • Software development experience in C++.
  • Experience in technical analysis scripting and visualization via Matlab or Python.
  • Experience with attitude determination.
  • Experience with state estimation algorithms.


  • Master's degree or PhD in physics or an engineering discipline.
  • Demonstrated project or professional experience in state estimation, feedback control, robotics, antenna design and actuation, or similar.
  • Direct experience with inertial navigation systems.
  • Direct experience with GNSS.
    • Multi-GNSS measurement models.
    • Loosely/tightly coupled state estimation.
    • Carrier phase compensation and integer ambiguity resolution.
    • Ionospheric compensation and modeling via radio occultation measurements.
    • Externally supplied constellation ephemeris + clock augmentation.
    • PPP/RTK.
    • Experience with GNSS receiver and antenna hardware and integration (time synchronization, PTP, PPS, receiver firmware and RTCM protocol).
  • Direct experience with phased array antenna systems.
  • Linux development experience.
  • Strong understanding of classical dynamics, modeling and simulation, and software development.
  • Capable of identifying and solving complex problems with little to no supervision or direction.
  • Passion for advancing the commercial space industry.
  • Ability to work in a fast paced, autonomously driven, and demanding start-up atmosphere.
  • Excellent communication skills both written and verbal.


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