Senior Thermal Engineer

About the Role
Uber is launching AV Labs to accelerate the autonomous technology ecosystem. We're building out a high-velocity team of multi-disciplinary experts to turn real-world operations into high-quality data for our autonomous partners. This team is focused on the hardest problem in AV today: unlocking real-world, long-tail driving data. Autonomy is now a data race—and Uber has an edge: We collect rare, real-world driving data at a scale and capital efficiency no one else can match.
As a Senior Thermal Engineer at Uber AV Labs, you will own thermal design, validation, and troubleshooting for autonomous vehicle hardware. This is a highly hands-on role working directly with sensors, compute systems, vehicle hardware, and environmental systems from prototype through production.
Core Responsibilities
Own end to end thermal design and validation for vehicle hardware, including compute units, power electronics and sensor systems
Design practical thermal solutions using liquid cooling, conduction, convection, heat sinks, fans/blowers, heaters, insulation, and thermal interface materials.
Design and develop liquid cooling systems, including coolant loops, cold plates, pumps, heat exchangers/radiators, reservoirs, valves, hoses, and vehicle integration.
Build and instrument prototypes; perform bench, thermal chamber, and vehicle testing across hot/cold environmental conditions.
Perform thermal and fluid calculations to size cooling components and evaluate system performance.
Use thermal/CFD simulation where appropriate and correlate models against physical test data.
Troubleshoot thermal and cooling-system issues directly on vehicles and hardware, identify root causes, and implement corrective actions.
Work closely with mechanical, electrical, sensor, compute, vehicle integration, and operation teams.
Drive designs from early prototype through validation builds and release in production.
Basic Qualifications
BS/MS in Mechanical Engineering or a related engineering discipline.
