Sr Materials Engineer, Wet Processing (Ingot/Wafer)

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. SR MATERIALS ENGINEER, WET PROCESSING (INGOT/WAFER) Starlink is building the world's largest satellite constellation to deliver fast, reliable internet to people who need it most—and powering that constellation starts on the factory floor. We are insourcing solar cell manufacturing end-to-end, from crystal growth and ingot production through wafering and cell fabrication, to drive performance, cost, and scale at every step. High-efficiency, high-reliability cells made in-house are the backbone of the Starlink network: more photons in means more data out to customers around the world. As a Sr. Materials Engineer for wet processing, you will set the technical bar for the chemistry, materials, and surface-quality outcomes of the wet steps that turn silicon ingots into production-ready wafers. That includes degumming, saw-damage etch, wafer cleaning, surface conditioning, chemical recycle/reclaim, and the wet-process chemicals that feed them. You will own the wet-process strategy from path-finding through golden-line and high-volume hand-off; solve the hardest contamination, etch, and supply-chain problems that stand between us and reliable wafer production at rate; and mentor partner teams on first-principles wet chemistry.
