Tasks

Why Join Us: At QuantumScape, you will help establish the Cell Test Methods and Analytics function for lithium-metal batteries, shaping how new cells are screened and qualified for reliability and yield. Your work will directly influence how fast we can bring breakthrough technology from development to production and ensure that our product consistently meets the highest standards for performance and safety. This role focuses on standardizing, automating, and optimizing test methods so that every development and production cell is evaluated through robust, data-driven screens. By developing better cell screens, you will prevent reliability risks and accelerate qualifications of new designs, materials, and processes. -Build and lead a high-performing team of test engineers and data scientists to execute screening strategies at scale -Apply statistical models and reliability analysis (e.g., Weibull, competing risk, hazard estimation) to quantify risk and optimize test design. -Coordinate test strategies across multiple development teams -Architect product test methods that define test coverage, mitigates test escape risks, and adapt to evolving product and process needs. -Establish automated test workflows and data pipelines to handle large-scale test data with high accuracy, repeatability, and throughput. -Develop and validate advanced cell screens that detect reliability risks and accelerate product qualification. -Correlate upstream process and metrology data with downstream reliability outcomes to continuously improve screening strategies. -Define screening specifications and adaptive test limits that balance reliability risk, yield, and efficiency. -Deliver clear, actionable feedback to development and manufacturing teams through reports, dashboards, and reviews. -Collaborate cross-functionally with Reliability, Manufacturing, Metrology, and Failure Analysis teams to align CTQs (Critical To Quality) and integrate them into screening flows.
