Sr. Software Engineer, High Performance Computing (Starlink)

Sr. Software Engineer, High Performance Computing (Starlink) 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. 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. 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 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 in order 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 at least 5 years of professional experience in software development; or 7 years of professional experience in lieu of a degree. Development experience in assembly, C, or C++. Preferred Skills and 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. Additional Requirements Must be willing to work extended hours and weekends as needed.
