Job description

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.

What we need:

We're looking for a Senior Cell Development Engineer to scope and lead end-to-end development efforts that directly impact cell performance and reliability. You'll lead projects to devise innovative cell designs, specify and optimize assembly processes, and integrate new materials/components into our anode-less solid-state batteries. You'll partner across automation, metrology, FA and manufacturing, owning projects and driving them to completion.

What You'll do:

• Lead integration and validation of new components and materials on next-generation cell platforms.
• Develop methodologies and experiments to validate key cell design performance, reliability, and safety criteria.
• Design rigorous DOEs; apply statistical and analytical methods to evaluate approaches and compare effectiveness.
• Model reliability performance (e.g., Weibull, Kaplan-Meier) and connect mechanisms to actionable design/process changes.
• Define critical-to-quality (CTQ) metrics, acceptance criteria, and validation plans.
• Collaborate with cell build process teams, equipment design teams, safety, quality, metrology, and production teams to execute on critical path projects.

Skills You'll Need:

• BS or higher degree in engineering, materials science, physics, or a related field.
• Minimum of Master's degree with 3+ years of relevant experience; OR Bachelor's degree with 5+ years of relevant experience.
• Proven track record of leading projects to successful completion.
• Prior experience in or knowledge of electrochemistry/electrochemical systems and battery test methods.
• R&D process-development experience (cell assembly, metrology, process specs, scale-up).
• Prior experience with Python for data analysis/visualization; solid statistics (DoE, regression, confidence intervals).
• Excellent technical communication and cross-functional collaboration.

Nice to have:

• Reliability analysis experience (Weibull, survival analysis, life test planning).

ONSITE:

This position is required to work on-site 5 days per week to meet the minimum essential duties and requirements of this position. As an on-site R&D and manufacturing operations organization, in-person face to face interaction is essential to building authentic relationships, trust, teamwork, and collaboration.

Compensation & Benefits:

Expected salary range for this role is from $112,500 to $163,200, and a final salary will be determined by the candidate's experience, educational background and internal equity.
