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.

Starlink believes in providing fast, reliable internet to those that need it most. We design, build, and launch the world's largest and most advanced satellite constellation that is capable of delivering high-speed internet to even the most remote locations.

As a Device Physics Engineer for Solar Cells, you will lead end-to-end cell efficiency ownership in our high-volume silicon heterojunction (SHJ) solar cell fab. Acting as the central process integration expert, you will collaborate with specialized process and equipment engineers to maximize cell performance to achieve state of the art efficiency. Your work will span from ingot growth all the way through cell production and module fabrication, ensuring our solar cells deliver unmatched power density and durability for Starship, Starlink, AI Satellites, and deep-space missions.

You will spearhead state of the art production processes and work through the entire life cycle of setting up a greenfield solar cell production plant. This includes equipment and lab procurement, plant design and layout, equipment commissioning and ramp-up, recipe and process development, and building a world-class production team and environment. Your work will form the backbone of the Starlink network, where photons of sunlight in are directly proportional to photons of data out to customers, helping provide internet to tens of millions of customers all around the world.

SpaceX is an Equal Opportunity Employer; employment with SpaceX is governed on the basis of merit, competence and qualifications and will not be influenced in any manner by race, color, religion, gender, national origin/ethnicity, veteran status, disability status, age, sexual orientation, gender identity, marital status, mental or physical disability or any other legally protected status.
