SMTS, Device Test and Characterization Engineer
About The Position
QuantumScape is seeking a Senior Member of Technical Staff (SMTS), Device Test and Characterization Engineer to join the Product Engineering, Quality and Reliability team. This role will own cell-to-product electrical test, characterization, qualification, and validation. The ideal candidate will design and execute electrical tests, develop stress and screening protocols to drive down DPPM, and build algorithms and statistical models to improve test coverage and predictive power. This is a new role for someone who is hands-on, curious, and ready to help define how test and characterization scale from cell to product as QuantumScape moves towards high-volume production. The SMTS will have the ability to shape how QuantumScape 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.
Requirements
- MS degree in Electrical Engineering, Materials Science, Chemical Engineering, Physics, or a related field, with 3+ years of relevant experience (or equivalent combination of education and experience); advanced degree (PhD) may offset years of experience
- Strong hands-on experience with electrical testing across cell, module, and/or product/pack-level assemblies (battery cells, battery systems, semiconductor devices, or similar), including test equipment specification and data acquisition
- Demonstrated experience with reliability engineering methods: qualification testing, accelerated stress testing (HALT/HAST-type approaches), failure analysis, and DPPM reduction, ideally applied at more than one level of a product’s build hierarchy
- Proficiency in statistical analysis and scripting (e.g., Python, MATLAB, or R) for building test algorithms, screens, and degradation models
- Working knowledge of DOE, SPC, and root-cause methodologies (e.g., 8D, fishbone/Ishikawa, FMEA)
- Ability to work cross-functionally with process, product, design, systems, and quality engineering teams in a fast-paced environment
- Excellent written and verbal communication skills, with the ability to present technical results to varied audiences
Nice To Haves
- Experience with battery-specific test techniques (e.g. EIS, DCIR, cycling protocols)
- Experience with module- or pack-level test and validation (thermal, mechanical, electrical tests)
Responsibilities
- 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 to align qualification and test strategy end-to-end; specify and help procure test equipment, and build dashboards to track test results, yield, and reliability trends across the build hierarchy
Benefits
- annual bonus
- generous RSU/Equity package
- employee paid health care
- Employee Stock Purchase Plan (ESPP)
