Sr. Embedded Software Engineer, Laser Mesh Routing (Starlink)

Sr. Embedded Software Engineer, Laser Mesh Routing (Starlink)

SpaceX was founded under the belief that a future where humanity is 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 millions of 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. All Starlink satellites have laser terminals to connect with other Starlink satellites, creating a large laser mesh network in orbit. We’ve only begun to scratch the surface of Starlink’s potential global impact and are looking for the world’s best engineers to help maximize Starlink’s utility for communities and businesses around the globe.

As a Beam Planning Software and Network Software Engineer on the Starlink program, you will be solving challenges that improve our ability to fully utilize the hardware we have deployed. Our goal is to provide customers with the best possible satellite internet experience, often providing under‑served communities with affordable, life‑changing broadband internet access.

Our software engineers are responsible for the complete lifecycle of the software they create, including development, testing, and support. We expect our engineers to close the feedback loop between software design and real‑world performance. In this role, your software will have a meaningful and measurable impact on the world.

Responsibilities

• Develop highly reliable, real‑time software that determines which beams (user, laser, gateway, etc.) should be formed to provide the best possible user experience for our low‑latency, high‑bandwidth satellite‑based global network.
• Participate in and lead architecture, design, and code reviews.
• Develop prototypes and manage experiments to prove out key design concepts.
• Develop tools for software development and deployment, data analysis and visualization, and test execution across multiple environments, including virtualized hardware environments, real hardware‑in‑the‑loop simulations, and on‑orbit testing.

Basic Qualifications

• Bachelor’s degree in computer science, engineering, math, or STEM discipline and 5+ years of professional experience in software development; OR 7+ years of professional experience in software development in lieu of a degree.
• Development experience in assembly, C, or C++.

Preferred Skills & Experience

• Knowledgeable in real‑time rendering, game engine development, physics simulation, or other real‑time, resource‑constrained, high‑performance computing.
• Knowledgeable in network topology, numerical optimization techniques, graph theoretic approaches, or convex optimization.
• Developed, debugged, and deployed software that has been used in real world applications/projects.
• Creative approach to problem solving, exceptional analytical skills, and engineering fundamentals.
• Excellent communication skills both written and verbal.
• Ability to work effectively in a dynamic environment with changing needs and requirements.
• Experience with distributed systems and internet services.
