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 Thermal/ Mechanical Engineer, you own the physical design of the product. You translate circuit boards and battery packs into a manufacturable shelf that fits the rack, survives the data center environment, and can be serviced by a technician in seconds.\nWhy this role matters: Hyperscalers don't negotiate on rack geometry. If the shelf doesn't fit, doesn't cool, or can't be serviced in seconds, it doesn't get evaluated- regardless of how good the electrical design is. You are also the company's primary interface to the hyperscaler's mechanical integration team during qualification. Your design fluency with their unwritten preferences (not just the published specs) can compress the qualification timeline by months. In a product where power electronics and battery cells share a tight enclosure, you are the person who makes coexistence physically possible.\nWhat you'll do:\nDesign the complete mechanical enclosure (1OU or 2OU shelf) in SolidWorks or Creo: sheet metal chassis, busbar routing, internal structural supports, and external connector interfaces\nSolve the core thermal challenge: power semiconductors and magnetics (tolerant to 100-125°C junction) sharing an enclosure with solid-state battery cells (requiring sub-45-60°C operation) - via directed airflow paths, thermal isolation zones, heat spreaders, and fan selection\nRun CFD simulations (Ansys Icepak, FloTHERM, or 6SigmaET) to optimize airflow distribution under worst-case conditions: full electrical load, 35-40°C inlet air (ASHRAE A1/A2), fan degradation scenarios\nDesign to OCP ORv3 mechanical specifications:shelf width, depth, connector position, airflow direction (front-to-back), ejector handle placement, guide rail interface, and weight-per-OU limits\nDevelop the hot-swap sled mechanism with proper insertion/extraction force curves, blind-mate power connector alignment, and guide rail compliance for tool-less serviceability\nCollaborate with the battery systems engineer on cell pack mounting, compression, thermal interface materials, and mechanical isolation within the enclosure\nPerform vibration and shock analysis for shipping (ISTA 3-series) and seismic requirements (GR-63-CORE or Bellcore Zone 4)\nLead DFM engagement with contract manufacturers: tolerances, tooling, bend radii, spot welding, PEM fastener insertion, and assembly sequence optimization\nSupport UL 62368-1 mechanical and flammability requirements (material selection for 94 V-0, spacing, enclosure integrity)\nInterface directly with hyperscaler mechanical integration teams during qualification reviews\nWhat you bring:\n8+ years designing thermal-mechanical enclosures for rack-mount power, compute, or telecom equipment\nRelevant 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 \nDemonstrated experience with CFD thermal simulation tools (Ansys Icepak, FloTHERM, or 6SigmaET) - not optional\nProficiency in SolidWorks or Creo for detailed mechanical design\nSheet metal design for volume manufacturing (bend radii, punching/stamping, spot welding, tolerance stackup analysis)\nTrack record of designs that went through contract manufacturing and passed thermal validation in a production or data center environment\nUnderstanding of airflow management in forced-convection rack environments\nNice to have:\nDirect experience with OCP Open Rack/ ORv3 mechanical specifications\nPrior work on battery pack thermal management (EV, stationary storage, or telecom backup)\nExposure to liquid cooling or cold plate design (emerging trend for rack power shelves)\nExperience with blind-mate connector integration (Amphenol, TE Connectivity, or Molex high-power connectors)\nFamiliarity with UL 62368-1 mechanical/flammability requirements and UL 1973 battery enclosure requirements\nKnowledge of IP67/NEMA ratings for potential edge or outdoor deployment variants\nExperience with vibration/shock testing per ISTA 3-series or GR-63-CORE\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.
