QuantumScape is on a mission to transform energy storage with solid-state lithium-metal battery technology. The company’s next-generation batteries are designed to enable greater energy density, faster charging and enhanced safety to support the transition away from legacy energy sources toward a lower carbon future.

About the team: Manufacturing Quality is a diverse group of engineers and data scientists who bring deep expertise in materials science, electrochemistry, statistics, and machine learning. Our team thrives on data-driven decision-making and a shared commitment to drive continuous improvement to QuantumScape’s solid-state battery technology. We work closely with the Manufacturing, Reliability, and R&D, groups to identify failure modes, engineer critical-to-quality specifications, and implement robust control strategies across all process areas.

What we need: We are seeking a Senior Engineer with industry experience in Process Quality. In this role, you will collaborate with process owners and operators to implement control strategies across QuantumScape’s cell and separator manufacturing lines

The ideal candidate thrives in a lab environment, is passional about optimizing tools and processes, values consistency and documentation, and has a proven track record with statistical analysis. If this role sounds like a good fit, we’d like to hear from you.
