Sr. Electrical Design Engineer, Laser Powder Bed Fusion Printers (Raptor)

SpaceX•Hawthorne, CA

1d•$140,000 - $230,000

About The Position

The Raptor Printer team designs, builds, and integrates in-house Laser Powder Bed Fusion (LPBF) printers that enable high-volume production of Raptor engines. We own the full product lifecycle of these critical manufacturing systems—from concept through production deployment—and continuously push the boundaries of additive manufacturing reliability, performance, and scale. As a Senior Electrical Design Engineer on this team, you will be the extreme owner of electrical systems for next-generation LPBF printers. You will drive requirements definition, circuit design, development, qualification, and seamless integration into production. This role offers end-to-end ownership of complex electromechanical systems in a high-stakes, fast-paced environment where your designs directly impact rocket engine production rates and reliability.
