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.\nAbout the role: As a hardware engineer, you own the electrical design of the battery management system. From AFE architecture to temperature monitoring, to selecting fuses and FETs for protection, you ensure the battery pack can work reliably under all conditions without compromising safety.\nWhy this role matters: As the hardware engineer for battery systems, you are responsible for all design aspects of the battery management system. You will collaborate closely with the mechanical engineering team to create state-of-the-art designs with high power and energy density, while meeting all regulatory safety requirements. You will also work with the firmware team closely to ensure all functions are implemented properly and validated thoroughly.\nWhat you'll do:\nDesign BMS system with pack voltages up to 600V and power >20kW\nCreate schematics and design PCB for the BMS\nDefine connection for voltage sensing, balancing and temperature monitoring\nSelect protection devices based on worst case operating conditions\nCollaborate with mechanical engineers to design heat sinks and wiring harnesses\nImplement inrush current limiting features\nEnsure hardware redundancy on critical protection functions\nClosely work with marketing team to generate detailed engineering specifications\nPerform design margin analysis and DFMEA\nSpecify design verification tests to ensure functional performance and regulatory compliance of the battery pack\nSupport UL 1973 and UL 9540A safety certification activities\nWork with external design teams to ensure the battery pack integrates well in its application\nWhat you bring:\na relevant Bachelor’s degree and 9+ years’ experience or a relevant Master’s degree and 8+ years’ experience or relevant Ph.D. and 5+ years’ experience \n5+ years in battery pack or BMS design with at least two products through prototype validation or production\nFamiliar with schematic and PCB design tools like Altium or Cadence\nIn depth understanding of Li-Ion battery technology and protections\nExpertise in designing analog, digital and generic power circuits, especially on low power design for battery applications\nFamiliar with simulation tools such as PSPICE, LTSpice, Simulink and PSIM\nGood PCB layout knowledge including high-speed design, thermal design, design for manufacturing and EMI mitigation techniques.\nUnderstand component management and BOM structures, capable of identifying agency critical components and verifying safety specifications\nExperienced in designing, bringing up, testing and troubleshooting brand new platforms\nAnalysis of circuit components, including their thermal and magnetic properties\nGood understanding of grounding, isolation, creepage/clearance and hi-pot testing\nCapable of creating thorough DVT plans to validate product specifications\nDesign for reliability using tools such as design margin analysis, DFMEA and HALT\nExperience with battery safety standards, such as UL1973, UL9540A and IEC62619\nComfortable of collaborating with mechanical, firmware and marketing teams.\nGood at generating engineering documentation such as specifications, block diagrams, design review presentations, assembly drawings, and test reports\nNice to have:\nPrevious experience in Data center power and energy products (CBU/BBU/EBM, etc)\nHands-on PCB layout experience\nDirect experience supporting PCBA manufacturing\nHigh-voltage battery pack design up to 800V+\nHigh-current design of >100A\nExperience in scalable modular systems with hot-swap capabilities\nExperience in a customer facing application engineering role\nKnowledge of power electronic circuits (AC/DC, DC/DC, Inverter, etc)\nONSITE: 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.\nCompensation & Benefits: Expected salary range for this role is from $136,700 to $208,500, 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.\nWe are an equal opportunity employer and value diversity at our company. We do not discriminate on the basis of race, religion, color, national origin, gender, sexual orientation, age, marital status, veteran status, or disability status.\nWe will ensure that individuals with disabilities are provided reasonable accommodation to participate in the job application or interview process, to perform essential job functions, and to receive benefits and privileges of employment.
