QuantumScape developed the industry’s first anode-less cell design, which delivers high energy density while lowering material costs and simplifying manufacturing. Our innovative battery cell technology can store energy more efficiently and reliably than today’s lithium-ion batteries.

We are seeking a highly motivated individual with a data science background to support our Film Specification R&D team. As a team member, you will help identify performance-limiting defect modes in our solid-state separator and define specifications to further improve our product performance and reliability. This position is an exciting multi-functional role that sits at the intersection of materials, manufacturing, and data science!

In this role, you will:

• Analyze correlations between upstream metrology of the ceramic separator and cell test data. Identify metrics most predictive of electrical performance.
• Collaborate with metrology engineers to generate new metrics and/or machine learning models to capture defect modes from 2D/3D images.
• Continuously report performance of existing film specifications and suggest opportunities for spec tightening or loosening.
• Communicate findings with audiences through clear and concise reports, presentations and data visualizations
• MS degree with 3+ years experience in Data Science, Computer Science, Engineering, Applied Math, Applied Physics or related area, or BS degree with 5+ years experience
• 3+ years of Data or Machine learning Science experience working on highly complex problems in a dynamic setting
• Technical expertise and in-depth knowledge in one or more of the following Data Science techniques: regression analysis, classification modeling, cluster analysis, predictive analytics, deep learning and CNNs, etc.
• Strong programming skills, especially in Python, with 3+ years of relevant experience in a programming intensive role
• Solid foundation in statistics

Highly desired:

• Experience in development of engineering or manufacturing specifications
• Fundamental knowledge of battery electrochemistries and failure mechanisms
• Familiarity with battery test data and metrics
• Understanding of Statistic Process Control and experience with Six Sigma

Skills & Abilities:

• You have a curious, hands‑on approach to problem solving.
• You are a strong communicator and love working in a fast-paced, team setting.
• Your time‑management skills allow you to independently balance multiple high‑impact efforts.
• You apply your resourcefulness to develop new skills, and you’re not shy about asking questions.
• You share a real passion for our mission.
