Job Title: Thermal Test Engineer

Job Description

As a Thermal Test Engineer, you will take a leading role in designing and executing comprehensive test plans that validate the performance of thermal systems including battery conditioning, cabin climate control, powertrain cooling, and HVAC components. You will be responsible for shaping validation strategy, driving root cause investigations, and ensuring our systems meet stringent quality and reliability targets in real-world conditions. This role offers the opportunity to work across multiple vehicle programs—from current production to future platforms—and to collaborate closely with design, integration, reliability, manufacturing, and software teams. You will have the autonomy to lead test initiatives, improve methodologies, and mentor junior engineers, while influencing the design of next-generation thermal systems through data-driven insights. We are looking for a highly motivated engineer with strong technical fundamentals, hands-on experience in vehicle or component-level testing, and a passion for problem-solving in a fast-paced, collaborative environment. If you are excited about working at the intersection of innovation and impact, and want to help shape the future of electric vehicles, we would love to hear from you.
