Missão
Job Summary
We are seeking an experienced Design Release Engineer (DRE) – Powertrain Cooling Systems to lead the end-to-end design, integration, validation, and release of thermal management components dedicated to power generation and propulsion units. In this role, you will own the cooling loops for internal combustion engines (ICE), turbochargers, transmission/axle oil circuits, and electric drive units (e-motors, inverters, and reduction gearboxes).
You will manage components through the full development cycle from initial concept to Start of Production (SOP)—ensuring optimal operating temperatures, durability, heat rejection, and fluid dynamics under extreme duty cycles.
Key Responsibilities
1. Component Design & Vehicle Integration
Lead the CAD design, spatial packaging, and routing of engine/e-motor coolant jackets, mechanical and electric water pumps, thermostats, multi-way rotary valves, transmission oil coolers (TOC), engine oil coolers (EOC), and charge air coolers (CAC).
Package heat exchangers, fluid lines, and mounting brackets within tight engine bay and drive-unit envelopes, ensuring proper clearance for engine movement, heat radiation, and chassis dynamics.
Implement Design for Manufacturability and Assembly (DFMA) principles to facilitate efficient assembly plant installation and service access.

2. Thermal Performance & Validation
Develop and execute the Design Verification Plan and Report (DVP&R), enforcing standards for heat rejection capacity, thermal shock, pressure drop, burst pressure, fluid compatibility, and flow distribution.
Collaborate with 1D/3D CFD and thermal simulation engineers (GT-SUITE, AMESim, Ansys Fluent) to optimize coolant flow rates, cavitation limits, and warm-up times.
Support climate wind tunnel testing, high-altitude trail runs, hot/cold weather vehicle testing, and physical prototype evaluations.
Lead root cause analysis (8D, 5 Whys, Fishbone) for fluid leaks, thermal degradation, pump cavitation, or overheating issues.
