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.


SpaceX is developing a low latency, broadband internet system to meet the needs of consumers across the globe. Enabled by a constellation of low Earth orbit satellites, Starlink will provide fast, reliable internet to populations with little or no connectivity, including those in rural communities and places where existing services are too expensive or unreliable.

Working directly in the materials engineering group, this position will provide expertise and capability in building processes for the production of injection molds. You will make an impact on SpaceX’s Starlink product components alongside a strong group of mechanical and process engineers. The goal of the team is to develop new manufacturing methods, commission equipment and qualify processes to be introduced into production.
