Job Description:

Product Engineer – Thermal Systems (Automotive / EV)

Overview / Summary

We are seeking a Product Engineer – Thermal Systems to lead the mechanical design and development of thermal system hardware for automotive applications. This role involves designing and developing components and assemblies across coolant, refrigeration, and HVAC/climate control subsystems, translating system performance and packaging requirements into detailed, manufacturable designs.

The ideal candidate will have a strong background in mechanical engineering, 3D CAD design, automotive product development, GD&T, and design for manufacturing and assembly.

Key Responsibilities

• Lead the mechanical design of thermal system hardware across one or more subsystems, from concept development through production release.
• Design thermal components and assemblies across coolant, refrigeration, and HVAC/climate control systems using 3D CAD tools.
• Package and route thermal hardware within vehicle architectures while resolving space, interface, and clearance constraints with adjacent systems.
• Translate thermal, hydraulic, and refrigerant performance requirements into physical designs that meet thermal, pressure, and flow targets.
• Develop designs optimized for manufacturing processes, including injection molding, brazing, stamping, extrusion, and machining.
• Collaborate with suppliers on tooling and manufacturing feasibility to balance cost, weight, and quality.
• Apply GD&T principles, perform tolerance stack-up analysis, and define critical dimensions to ensure component fit, sealing, and functionality.
• Support structural, flow, thermal, and durability analysis in collaboration with engineering analysis teams.
• Utilize DFMEA to identify and mitigate potential design failure modes.
• Create and release detailed component and assembly drawings, manage engineering changes, and maintain CAD data and bills of materials throughout product development.
• Collaborate with system engineers, subsystem engineers, controls engineers, test engineers, and suppliers.
• Support design reviews, validation activities, and product launch readiness.

Required Qualifications

• Bachelor's degree in Mechanical Engineering or a related engineering discipline.
• Minimum of 3 years of experience in mechanical design of automotive components or systems.
• Proficiency in 3D CAD tools such as CATIA, Siemens NX, or 3DEXPERIENCE for part and assembly modeling and detailing.
• Working knowledge of Geometric Dimensioning and Tolerancing (GD&T) and tolerance stack-up analysis.
• Understanding of Design for Manufacturing and Assembly (DFM/DFA) across multiple manufacturing processes, such as molding, brazing, and stamping.
• Familiarity with heat transfer, fluid dynamics, and pressure-system fundamentals as applied to thermal hardware.

Preferred Qualifications

• Master's degree in a relevant engineering discipline.
• Direct experience designing thermal hardware, including coolant loops, refrigeration or heat-pump circuits, heat exchangers, or HVAC units.
• Experience with electric vehicle (EV) thermal management systems, including battery, drive unit, power electronics, and cabin heating and cooling.
• Familiarity with refrigeration and HVAC systems.
• Experience with actuator- and valve-driven hardware and control interfaces.
• Experience with DFMEA, DVP&R, and production part release and engineering change management processes.
