Automotive Thermal Systems Engineer - CAD Expert

Insight Global; Long Beach (CA); On-site; USD 90,000 - 130,000; Full time

Job summary

Insight Global is seeking an experienced mechanical engineer to own and advance the thermal system design for automotive hardware—from concept through production release. You will design coolant, refrigeration, heat pump, and HVAC components using 3D CAD and ensure manufacturability across processes, while collaborating with cross-functional teams to ensure validation and production readiness.

The role requires 3+ years in automotive design, strong GD&T, and experience with EV thermal

Qualifications

• Bachelor's degree in Mechanical Engineering or related discipline, or equivalent practical experience.
• 3+ years of experience designing automotive components or systems.
• Proficiency with CATIA, NX, or 3DEXPERIENCE.
• Strong understanding of GD&T and tolerance stack-up analysis.
• Knowledge of DFM and DFA principles across multiple manufacturing processes.
• Familiarity with heat transfer, fluid dynamics, and pressure-system fundamentals.
• Master's degree in Mechanical Engineering or related discipline.
• Experience designing thermal system hardware, including coolant loops, refrigeration/heat pump systems, HVAC units, or heat exchangers.
• Background in EV thermal management systems supporting batteries, drive units, power electronics, and cabin climate control.

Responsibilities

• Own the mechanical design of thermal system hardware from concept through production release.
• Design components and assemblies across coolant, refrigeration, heat pump, and HVAC subsystems using 3D CAD.
• Package and route thermal hardware throughout the vehicle, resolving space constraints with other systems.
• Convert thermal/hydraulic/refrigerant requirements into physical hardware designs, including flow paths and heat exchanger integration.
• Develop designs optimized for manufacturing and assembly (injection molding, brazing, stamping, extrusion, machining).
• Apply GD&T, perform tolerance stack-up analyses, and establish critical dimensions for fit and seal.
• Support CFD, FEA, durability, and thermal analyses; use DFMEA to mitigate design risks.
• Create and release drawings, maintain CAD models and BOMs, manage engineering changes.
• Collaborate with systems engineers, controls, test, manufacturing teams, and suppliers for validation and production readiness.
