Compensation
USA, WA, Seattle - 136,000.00 - 184,000.00 USD annually
Responsibilities
- Develop high-fidelity FEA and CFD thermal models of the drone's battery pack, motors, power electronics, and avionics, capturing conduction, convection, and radiation across the full flight envelope and ambient operating range.
- Define and develop thermal management strategies and systems for the battery pack, including cold-weather heating, in-flight and ground cooling, and cell-to-cell temperature uniformity.
- Develop cooling strategies for electric motors and motor controllers, including forced-air and conductive paths, and trade thermal performance against mass, drag, and packaging constraints.
- Analyze candidate designs and quantify thermal margins, hot-spot locations, transient temperature response, and sensitivity to operating conditions, and communicate results as clear design recommendations.
- Perform thermal analysis of avionics systems, defining heat-sinking, airflow, and conduction paths that maintain component junction temperatures within reliability limits.
Requirements
- Bachelor's degree in mechanical engineering or equivalent
- Nice to have: Master's degree in mechanical engineering or equivalent
- Nice to have: electric powertrain components
