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.

SOFTWARE ENGINEER (WIRELESS, DIRECT TO CELL)

The Direct to Cell network will expand Starlink’s vision by providing ubiquitous connectivity and seamless access to text, voice, and data for LTE phones and devices across the globe. The Direct to Cell network leverages the infrastructure we’ve built for Starlink over the past several years. Starlink is the world’s largest satellite constellation and is providing fast, reliable internet to 3M+ users worldwide. As the global leader in rocket and satellite launch and manufacturing, SpaceX is uniquely positioned to rapidly scale our Direct to Cell network and will rapidly launch a constellation of hundreds of satellites.

Developing a satellite network that connects to unmodified cell phones, in different parts of the world and in partnership with different operators, presents several new technical and regulatory challenges. We are looking for best-in-class engineers to help realize our goals to enable various communication services. Text service begins this year, followed by voice, data, and Internet of Things (IoT) services in 2025.

As a Software Engineer on the Starlink Direct to Cell program, you will be solving challenges underpinning every aspect of the program’s growth. The areas you could have an impact on include, but are not limited to, building:

  • Cellular technologies and 3GPP standards-based protocols ( LTE, 5G, 5G-NTN) and interfaces, on the satellite and ground, to enable an end-to-end mobile service.
  • Firmware, embedded and controls software running on custom hardware that powers the Cell Tower in space.
  • Infrastructure and tools to enable rapid development and reliable deployment of our code to dynamic production environments.

Our software engineers are responsible for the complete life cycle of the software they create, including development, testing, and support.

RESPONSIBILITIES:

  • Design, implement, test, maintain, and document various layers of the Direct-to-Cell wireless protocol stack.
  • Work with other teams for cross-layer integration of the protocol stack with other modules / layers.
  • Use network monitoring tools to analyze and monitor link layer performance. Debug and fix network reliability issues.
  • Participate in architecture, design, and code reviews.
  • Develop tools that allow for test execution across multiple environments: virtualized hardware, real hardware-in-the-loop simulations, and on-orbit testing.

BASIC QUALIFICATIONS:

  • Bachelor’s degree in computer science, electrical engineering, math, or related STEM discipline.
  • Software development experience in C/C++ in an embedded environment.
  • Experience working with wireless software or network protocols.

PREFERRED SKILLS AND EXPERIENCE:

  • Developed, debugged, and deployed software that has been used in real world projects or mobile/broadband service.
  • Strong knowledge of IP Networking protocols.
  • Prior experience with one or more of 3GPP protocols like RRC, RRM, SON, S1AP, RLC, PDCP.
  • Creative approach to problem solving, exceptional analytical skills and engineering fundamentals.
  • Strong skills in debugging, performance optimization, and unit testing.
  • Excellent communication skills both written and verbal.
  • Ability to work effectively in a dynamic environment with changing needs and requirements.

ADDITIONAL REQUIREMENTS:

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

COMPENSATION AND BENEFITS:

Pay range:
Software Engineer/Level I: $130,000.00 - $155,000.00/per year
