Sr. Screen Printing Equipment Engineer, Solar Cells (Starlink)

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. SCREEN PRINTING EQUIPMENT ENGINEER, SOLAR CELLS (STARLINK) 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 Sr. Screen Printing Equipment Engineer, you will own the screen printing and related metallization equipment used to manufacture silicon heterojunction solar cells at massive scale. You will work closely with our existing Metallization/Screen Printing Process Engineering team to ensure world-class equipment performance, reliability, and uptime. While the process team focuses on paste properties, contact formation, and cell efficiency, you will be the hardware owner responsible for tool availability, stability, and scaling to support our ambitious goals.   Your work will form the backbone of the Starlink network (photons of sunlight in is directly proportional to photons of data out to customers!) and help provide internet to tens of millions of customers all around the world. You will spearhead state of the art production equipment for an internal solar cell production line, providing high efficiency and high-quality solar cells for both our latest generation Starlink satellites and for Starship missions to the Moon and Mars.   RESPONSIBILITIES:   Work with facilities and process engineering teams to install, qualify, maintain, and continuously improve high-throughput screen printing equipment for heterojunction silicon solar cell manufacturing Drive equipment reliability and uptime to support very large volume production with minimal downtime. Run experiments and analyze data to improve capacity (UPH), reduce tool-to-tool variation, and improve defect performance Develop and execute robust preventive and predictive maintenance strategies, spare parts programs, and tool matching protocols for high-volume manufacturing Lead root cause analysis and corrective actions on all equipment-related issues, including print heads, squeegee systems, alignment/vision systems, conveyors, drying ovens, paste delivery, and automation Partner closely with Process Engineers to implement new process requirements on existing and future equipment platforms Evaluate and select next-generation high-throughput screen printing tools capable of supporting 1GW+ per tool scale production Work with vendors on equipment design improvements, upgrades, and custom solutions tailored to heterojunction solar cell requirements Establish equipment performance metrics (OEE, MTBF, MTTR) and implement statistical process control for hardware stability Ensure all equipment meets cleanroom, safety, and high-reliability manufacturing standards Analyze production processes and machinery from a first principles, physics-based approach Attend meetings to communicate factory state to leadership with respect to the team’s equipment   BASIC QUALIFICATIONS:   Bachelor’s degree in Mechanical Engineering, Electrical Engineering, Chemical Engineering, Materials Science, or related technical discipline 5+ years of hands-on experience owning and maintaining screen printing or metallization equipment in a high-volume semiconductor, solar manufacturing, or related environment Experience handling flammable, toxic, corrosive, and/or hazardous chemicals and materials safely (pastes, solvents, etc.)   PREFERRED SKILLS AND EXPERIENCE:   7+ years of hands-on experience owning and maintaining screen printing equipment in a high-volume semiconductor or solar manufacturing environment Strong technical expertise in screen printing systems, vision/alignment, paste handling, drying/curing ovens, conveyors, and automation hardware Demonstrated success improving equipment uptime and reliability in a 24/7 high-volume production setting Experience with heterojunction (HJT) silicon solar cell manufacturing equipment  Previous work at high-volume solar, semiconductor, or display manufacturing facilities (multi-GW or 300mm fab experience is a plus) Deep knowledge of screen printing tool architecture and subsystems Experience with screen tensioning, squeegee pressure control, print registration, paste rheology handling, and dryer temperature profiling Experience with electro-pneumatic robot and transfer module systems Experience with paste delivery systems and solvent handling Experience scaling equipment from pilot to very high volume production Proficiency with statistical tools (JMP, Minitab), failure analysis techniques, and reliability engineering principles Strong project management skills with the abil
