Senior Engineer, Mechanical Design

Senior Engineer, Mechanical DesignQuantumScape 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.The Hardware, Automation, and Metrology team is seeking a Senior Engineer, Mechanical Design, who is deeply experienced in automation equipment design and motivated by building first-of-a-kind manufacturing tools from concept to production. In this role, you will own the mechanical design of custom automation equipment across the full lifecycle—from early concept and prototyping through detailed design, build, FAT/SAT, and handoff to manufacturing—while working closely with systems, controls, electrical, process, and EHS partners. You will play a critical role in defining mechanical architecture, managing design risk, and ensuring designs are robust, manufacturable, serviceable, and safe.If you enjoy solving hard mechanical problems, mentoring others, and delivering real hardware that matters, we'd like to hear from you.What You'll Do:Lead the mechanical design and development of critical, first of a kind automation and process equipment supporting QuantumScape's next generation energy storage technology.Own mechanical design scope end to end, from early concept definition through detailed design, build, qualification, and handoff to manufacturing, with accountability for technical decisions, risk mitigation, and design readiness.Drive hands on mechanical design, prototyping, and validation to identify scalable, robust solutions suitable for volume production.Define mechanical architecture, subsystem interfaces, and design approaches while incorporating DFM/DFA, reliability, maintainability, and safety considerations.Partner closely with systems, controls, electrical, process, manufacturing, and EHS teams to deliver integrated equipment solutions across all phases of the design lifecycle, including specifications, design reviews, prototyping, assembly, testing, FAT/SAT, and continuous improvement.Provide technical leadership within the mechanical design function by mentoring engineers, influencing best practices, and helping shape mechanical design standards across HAM.Skills You'll Need:Master's degree or equivalent in Mechanical Engineering or a closely related field with typically 3+ years of relevant industry or applied engineering experience, or a Bachelor's degree with 5+ years of progressively responsible mechanical engineering experience; Ph.D. with no experience.Deep, hands-on expertise in mechanism, hardware, and automation equipment design, including ownership of complex mechanical systems.Practical experience with component manufacturing methods, including machining, additive manufacturing (3D printing), and sheet metal fabrication.Advanced proficiency in 3D CAD tools such as SolidWorks, Inventor, and CATIA, with the ability to produce production ready models and assemblies.Strong working knowledge of ASME Y14.5 GD&T standards and their application to detailed mechanical drawings.Demonstrated ability to apply strength of materials, machine design theory, and physics-based reasoning to estimate loads, assess factors of safety, select materials, and size mechanical components for reliability and scalability.Proven capability to exercise independent technical judgment, solve complex and ambiguous mechanical problems, and influence design best practices across teams.Effective collaborator across mechanical systems, controls, electrical, process, manufacturing, and EHS disciplines, with minimal supervision.Willingness to support limited travel requirements (approximately 5% domestic and 5% international) for supplier engagement, build reviews, and equipment qualification.Nice to have:1-2 years' experience with designing Solid state, li-Ion or Fuel cell battery cell manufacturing systems.Certified in GD&T standardsCertified in 3D CAD toolsPhysical requirements:Work is performed in a dry room, fume hood, lab area, or glovebox requiring the use of fine motor skillsSitting or standing for extended periods of timeReaching and twisting motions with handsLifting up to 25 lbs.ONSITE: This position is required to work onsite 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. QuantumScape also offers an annual bonus and a generous RSU/Equity package as part of its compensation plan. In addition, we do offer a tremendous benefits plan including employee paid health care, Employee Stock Purchase Plan (ESPP), and other benefits.
