This role requires 3+ years of hands-on vehicle calibration and testing experience to ensure thermal performance, component protection, energy efficiency, and occupant comfort across a wide range of operating and environmental conditions. The engineer will work closely with cross-functional teams to develop robust thermal control strategies and validate system performance through vehicle, dynamometer, and climatic chamber testing.\nResponsibilities:\nCalibrate and validate powertrain thermal management and cabin HVAC control systems to optimize thermal performance, energy efficiency, component protection, and occupant comfort.\nDevelop and tune thermal control strategies for pumps, fans, valves, compressors, coolant and refrigerant circuits, and heating/cooling devices.\nExecute powertrain thermal and HVAC calibration activities, including hot/cold soak, thermal protection, derate, warm-up, cool-down, defrost, demist, and cabin comfort testing.\nPerform hands-on vehicle testing, climatic chamber testing, and dynamometer evaluations to assess and improve thermal system performance under varying operating conditions.\nAnalyze vehicle data and instrumentation results to optimize coolant, refrigerant, airflow, temperature control, and overall thermal system effectiveness.\nCalibrate thermal management functions across a wide range of ambient temperatures, vehicle speeds, drive cycles, propulsion modes, charging conditions, and powertrain loads.\nValidate thermal system performance and control robustness through vehicle-level testing and real-world environmental assessments.\nUtilize calibration and data acquisition tools to troubleshoot system interactions and optimize integrated thermal and HVAC performance.\nSupport vehicle-level thermal system integration, balancing propulsion cooling/heating requirements, cabin comfort demands, energy consumption, and system constraints.\nCollaborate with systems, controls, software, and validation teams to achieve thermal performance, efficiency, durability, and customer comfort targets.\nRequirements\nBachelor's degree in mechanical engineering, Electrical Engineering, Automotive Engineering, or a related field.\n3+ years of hands-on experience in vehicle thermal management and HVAC calibration.\nProven experience conducting vehicle-level testing, climatic chamber testing, and dynamometer testing.\nStrong understanding of coolant systems, refrigerant systems, HVAC controls, thermal protection strategies, and vehicle energy management.\nExperience with calibration and data acquisition tools such as CANape, INCA, ETAS, Vector, or equivalent.\nProficiency in data analysis and calibration development using vehicle test data.\nExperience supporting thermal management systems for conventional, hybrid, or electric vehicles.\nPreferred Qualifications\nExperience with MATLAB/Simulink and controls development.\nExperience supporting EV, hybrid, or advanced propulsion thermal systems.\nKnowledge of thermal modeling, vehicle controls, and system integration.\nStrong troubleshooting and root-cause analysis skills.\nExperience collaborating with cross-functional engineering teams in a fast-paced vehicle development environment.","description_format":"text","description_chars":3365,"description_truncated":false,"requirements":{"experience_years_min":3,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Automotive
