Job Summary

We are seeking an experienced Design Release Engineer (DRE) – Cooling Systems to lead the end-to-end design, integration, validation, and release of vehicle thermal management components. In this role, you will be responsible for the complete cooling architecture—including radiators, electric water pumps, thermostats/control valves, expansion tanks (degas bottles), cooling fan modules, and coolant distribution lines.

You will manage the entire product lifecycle from concept through Start of Production (SOP), ensuring system performance across traditional Internal Combustion Engine (ICE) platforms, Hybrid powerpacks, and Battery Electric Vehicle (BEV) thermal loops.

Key Responsibilities

1. Component Design & Vehicle Integration

- Lead the CAD packaging and mechanical design of front-end cooling modules (CRFM), radiators, charge air coolers (CAC), oil coolers, electric water pumps, multi-way control valves, degas/expansion tanks, and shrouds/fans.

- Coordinate under-hood and under-body spatial packaging with Structural, Engine/E-Motor, Chassis, and Exterior Trim engineering teams to resolve clearance conflicts and optimize airflow.

- Apply Design for Manufacturability and Assembly (DFMA) principles to support efficient line installation and ergonomics at OEM assembly plants.

2. System Performance & Validation

- Develop and execute the Design Verification Plan and Report (DVP&R;),



enforcing standards for pressure drop, burst strength, thermal shock, vibration durability, flow rate balance, and NVH.

- Collaborate with Thermal CFD and 1D simulation engineers (GT-SUITE/AMESim) to evaluate flow distribution, heat dissipation, and cooling fan acoustic performance.

- Support climate wind tunnel testing, track trials, hot/cold weather testing, and physical prototype builds (PERs).

- Drive root cause analysis (8D, 5 Whys, Fishbone) for validation failures, coolant leaks, or assembly plant issues.

3. Change Management & Release Execution

- Author and release technical documentation including Design FMEAs (DFMEA), 2D engineering drawings, 3D CAD models, material specifications, and GD&T; tolerance schemes.

- Create and process Change Notices (CNs/ECNs) to track engineering changes, cost-reduction initiatives, and tooling updates.

- Approve Tool Kick-Off (TKO) requests, manage Source Package technical releases, and issue Interim Approval Authorizations (IAAs) when necessary.

4. Supplier & Cross-Functional Management

- Primary technical lead interfacing with Tier-1 cooling component and module suppliers through APQP / PPAP gateways.

- Partner with Purchasing, Quality, Manufacturing, and Systems Architecture teams to meet cost (Design-to-Cost), weight, and timing targets.
