Job summary

QuantumScape Battery, Inc. is seeking an experienced mechanical design engineer focused on thermal‑mechanical enclosures for rack-mounted power and data center applications.

You will design 1U/2U shelves, route busbars, ensure safe heat management, and support qualification with hyperscalers. You will run CFD simulations (Ansys Icepak, FloTHERM, 6SigmaET), collaborate with battery engineers on pack mounting, and drive DFM with contract manufacturers while meeting UL 62368-1 requirements.

Qualifications

• 8+ years designing thermal‑mechanical enclosures for rack-mounted power, compute, or telecom equipment.
• CFD thermal simulations experience with Ansys Icepak, FloTHERM, or 6SigmaET is required.
• Proficiency in SolidWorks or Creo for detailed mechanical design.
• Sheet metal design for volume manufacturing (bend radii, punching/stamping, tolerance stackup).
• Experience with contract manufacturing and passing thermal validation in production or data center environments.
• Understanding of airflow management in forced-convection rack environments.

Responsibilities

• Design the complete mechanical enclosure (1OU or 2OU) in SolidWorks or Creo: sheet metal chassis, busbar routing, internal supports, interfaces.
• Address core thermal challenges: joint cooling of power electronics and batteries; implement thermal isolation and heat spreaders.
• Run CFD simulations to optimize airflow under worst-case conditions (full electrical load, high inlet temps, fan degradation).
• Design to ORv3 mechanical specs: dimensions, connector positions, airflow direction, ejector handles, rail interfaces, weight per U.
• Develop hot-swap sled mechanism with insertion/extraction force curves and blind‑mate power connectors.
• Collaborate with battery systems engineer on cell pack mounting and mechanical isolation.
• Perform vibration/shock analysis for ISTA 3-series and GR-63-CORE seismic requirements.
• Lead DFM with contract manufacturers: tolerances, tooling, bend radii, spot welding, and assembly sequencing.
• Support UL 62368-1 mechanical and flammability requirements.
• Interface with hyperscaler mechanical teams during qualification reviews.
