Sr. Tooling Engineer, Plastic Injection Molding (Starlink)



Bastrop, TX, USA
Posted on Thursday, July 4, 2024

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 is responsible for the development, qualification, and implementation of all tooling and manufacturing process technologies required to deliver the right scalable solution at the right cost on time. The correct individual will bring an open mindset, challenge the status quo with regard to traditional vs. emerging technologies, and utilize a logical and disciplined approach to evaluate and select the correct set of solutions. The candidate will drive alignment between design, material, and process selection and will own the seamless integration of these processes into the overall process flow.

The ideal candidate will have a proven track record in consumer electronics product and tooling development with Domestic as well as Asian suppliers, tooling material selection, resin selection, and qualification, high volume manufacturing, secondary processes, DOE experience and the ability to run multiple programs in parallel with excellent communication and collaboration skills.
