What to Expect
Tesla is accelerating the world's transition to sustainable energy. Our Energy team is expanding solar production to deliver high-efficiency photovoltaic (PV) cells at scale, powering homes, businesses, and the grid with clean, affordable energy. As a Polysilicon Engineer, you will play a critical role inoptimizingand scaling polysilicon production processes-the foundational material for our next-generation solar cells. This is a hands-on role in a fast-paced, innovative environment where you will drive breakthroughs in material purity, yield, and cost reduction to enable Tesla's mission of sustainable energy for all.
What You'll Do
Lead the development, optimization, and scaling of polysilicon production processes, including Siemens reactor operations, chemical vapor deposition (CVD), and purification techniques Design and execute experiments to improve polysilicon quality, reduce impurities, and enhance energy efficiency in production Collaborate with cross-functional teams (materials science, cell engineering, manufacturing) to integrate high-purity polysilicon into solar wafer and cell fabrication Analyze process data toidentifybottlenecks, implement continuous improvements, and achieve aggressive yield and cost targets Troubleshoot production issues in real-time, ensuring safety, reliability, and high-throughput operations Develop andvalidatenew technologiesfor polysilicon recycling, waste reduction, and sustainable manufacturing Contribute to equipment design, automation, and pilot-to-production transitions in Tesla's solar facilities
What You'll Bring
- Degree in Chemical Engineering, Materials Science, Chemistry, or a related field or equivalent experience
3+ years of experience in polysilicon production, semiconductor materials, or solar PV manufacturing (experience with Siemens process orhyperpuresilicon highly desired) Strong knowledge of chemical vapor deposition (CVD), thermodynamics, fluid dynamics, and materials characterization techniques Proventrack recordof process optimization, yield improvement, and scaling production in high-volume environments Hands-on experience with data analysis tools (e.g., Python, JMP, MATLAB) and statistical process control Ability to thrive in a dynamic, mission-driven team with a bias for action andfirst-principlesthinking Excellent problem-solving skills and a passion for sustainable energy innovation
