Job summary

QuantumScape is hiring a Thermal/Mechanical Engineer to own the physical design of high-density rack-mount enclosures, integrating thermal and structural considerations with battery cells and power electronics. You will lead CAD design, CFD analysis, and collaboration with hyperscalers during qualification, ensuring manufacturability and serviceability in data center environments.

The role requires deep expertise in thermal management, enclosure design, and interface to contract manufacturers,

Qualifications

8+ years designing thermal-mechanical enclosures for rack-mount power, compute, or telecom equipment.
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.
Demonstrated experience with CFD thermal simulation tools (Ansys Icepak, FloTHERM, or 6SigmaET) - not optional.
Proficiency in SolidWorks or Creo for detailed mechanical design.
Sheet metal design for volume manufacturing (bend radii, punching/stamping, spot welding, tolerance stackup analysis).
Track record of designs that went through contract manufacturing and passed thermal validation in a production or data center environment.
Understanding of airflow management in forced-convection rack environments.

Responsibilities

Design the complete mechanical enclosure (1OU or 2OU shelf) in SolidWorks or Creo: sheet metal chassis, busbar routing, internal structural supports, and external connector interfaces
Solve the core thermal challenge: power semiconductors and magnetics sharing an enclosure with solid-state battery cells, with directed airflow paths and heat spreaders
Run CFD simulations to optimize airflow distribution under worst-case conditions and ambient temps
Design to mechanical specifications: shelf width/depth, connector position, airflow direction, ejector handle, rail interface, weight-per-OU
Develop hot-swap sled mechanism with insertion/extraction force curves and blind-mate power connector alignment
Collaborate with battery systems engineer on cell pack mounting and thermal interface materials
Perform vibration and shock analysis for shipping and seismic requirements
Lead DFM engagement with contract manufacturers: tolerances, tooling, bend radii, spot welding, assembly sequence
Support UL 62368-1 mechanical and flammability requirements
Interface with hyperscaler mechanical integration teams during qualification reviews
