Software Engineer; Starlink Mobile

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.

The Starlink Mobile 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. Leveraging the infrastructure built for Starlink, this role involves building reliable, real‑time software that supports global satellite‑based connectivity for mobile phones. As a software engineer on the Starlink Mobile program, you will handle the full software lifecycle – from development and testing to ongoing support – and close the loop between design and real‑world performance.

• Develop highly reliable, real‑time software that plans and executes network topology for a satellite‑based global network, maximizing user experience.
• Participate in and lead architecture, design, and code reviews.
• Build tools for software development and deployment, data analysis and visualization, and test execution across multiple environments, including virtualized hardware, real hardware‑in‑the‑loop simulations, and on‑orbit testing.
• Prototype and manage experiments to validate key design concepts.

• Bachelor’s degree in computer science, engineering, math, or a science discipline; OR 2+ years of professional software development experience in lieu of a degree.
• Development experience in Python, C, or C++.

• Knowledge of real‑time rendering, game engine development, physics simulation, or other real‑time, resource‑constrained, high‑performance computing environments.
• Knowledge of network topology, numerical optimization techniques, graph‑theoretic approaches, or convex optimization.
• Experience developing, debugging, and deploying software used in real‑world applications or projects.
• Creative problem‑solving ability, strong analytical skills, and solid engineering fundamentals.
• Excellent written and verbal communication skills.
• Experience with distributed systems and internet services.
• Ability to work effectively in a dynamic environment with evolving needs and requirements.

• Must be willing to work extended hours and/or weekends as needed.
• Position requires U.S. citizenship or a lawful permanent resident status, or eligibility to obtain necessary authorizations under U.S. export regulations (ITAR).
