Quantum Scape 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
:
The Quality & Reliability organization drives end-to-end quality ownership from fab process to product to customer. Within this organization team owns cell-to-product electrical test, characterization, qualification, and reliability - partnering closely with Design, Process, Manufacturing, and Quality Systems to ensure products meet performance, reliability, and customer requirements before they ship. The team prides itself on hands-on rigor, data-driven decision making, and catching problems early through disciplined test and screening strategy.

What we need: The Product Engineering, Quality and Reliability team is seeking a Senior Member of Technical Staff (SMTS), Device Test and Characterization Engineer to own cell-to-product electrical test, characterization, qualification, and validation. You will design and execute electrical tests, develop stress and screening protocols to drive down DPPM, and build algorithms and statistical models that improve test coverage and predictive power.

This is a new role, and we’re looking for someone who is hands‑on, curious, and ready to help define how test and characterization scale from cell to product as Quantum Scape moves towards high-volume production. If you like solving hard technical problems, building test capability from the ground up, and validating performance against real product and customer requirements, we’d like to hear from you.

As an SMTS, Device Test and Characterization Engineer, you will have the ability to shape how Quantum Scape tests, qualifies, and validates its products from cell through product level - directly influencing DPPM, AFR, reliability, and the pace at which new designs move from prototype to production.

What You’ll do:

• Design, execute, and interpret electrical tests spanning cell, module, and product-level assemblies (e.g., capacity, impedance, rate performance, cycle life testing) to characterize performance across the full build hierarchy and product lifecycle
• Develop new tests, characterization methods, and test protocols on electrical test equipment in the test labs, extending capability and coverage
• Lead root-cause analysis on electrical failures at any level of the hierarchy - cell, module, or product - connecting test data to physical and process root causes in partnership with process, materials, design, and systems engineering
• Own quality (Qual) and reliability (Rel) test plans spanning cell through product level for new designs and process changes, including definition of pass/fail criteria, sample sizing, and test-to-failure/margin studies
• Drive down defective parts per million (DPPM) across the build hierarchy by identifying failure modes, building detection screens, and closing the loop with corrective actions and process countermeasures
• Develop and validate stress tests and screening protocols - at cell and product level - that accelerate latent‑defect detection without introducing false rejects, and develop algorithms and statistical models to improve test coverage, throughput, and predictive power
• Validate cell and product performance against specifications and customer requirements, and support the transition from prototype to production test flows
• Partner with systems, module, and pack engineering teams…
