Job Description
What to Expect Tesla's In-House Cell Group is seeking a Laser Process Development Engineer to pioneer the welding, ablation, and cutting applications that define our next-generation battery cells. Based in Fremont, CA, you will be the subject matter expert bridging the gap between fundamental laser physics and high-volume automated reality. You aren't just managing a process; you are owning it. From initial "lab bench" experimentation and optical selection to scaling processes on massive pilot lines, you will drive the innovations that make Tesla's vertical integration possible. What You'll Do Innovate Processes: Develop novel laser applications (welding, cutting, ablation) and specify high-performance laser sources and optical delivery systems Experimental Mastery: Design and execute complex Design of Experiments (DOE) to map the process window and optimize for strength, conductivity, and speed Data-Driven Theory: Don't just observe-explain. Develop hypotheses for laser-material interactions and validate them through structured testing and cross-sectional analysis Statistical Rigor: Perform Measurement System Analysis (Gage R&R) and utilize statistical process control (SPC) to ensure every micron of every weld is accounted for Scale Up: Lead the technical transfer of processes from the lab to the production floor. Manage the installation, commissioning, and qualification (IQ/OQ/PQ) of laser-integrated automation Cross-Functional Leadership: Partner with Product Design to influence "Design for Manufacturability" (DFM) and collaborate with Controls and Quality to ensure 100% yield and uptime What You'll Bring Degree or Equivalent Experience in Mechanical Engineering, Materials Science, Physics, or Mechatronics 6+ years in process development, specifically transitioning technologies from pilot-scale to high-volume manu
