As a Staff Thermal Attributes Engineer at Rivian, you will be the Subject Matter Expert in underhood thermal performance and integration. Your primary focus will be on front-end airflow requirements and vehicle-level Active Grille Shutter strategy. You will collaborate with cross-functional teams to ensure that thermal and charging performance requirements are met. This role is crucial for driving design optimization and validating performance targets across various vehicle programs.

• Engineering Bachelor's or Master's Degree from an accredited University with a strong background in Thermal Science
• 10+ years of experience with automotive thermal attributes, systems, and components at an OEM or Tier 1 supplier
• Expert-level understanding of vehicle AGS, airflow duct and ORFM at both system and vehicle levels
• Strong fundamentals of heat-transfer and thermodynamic devices like heat exchangers, compressors, valves, pumps, fans, and heaters along with their subsystem and system-level interactions
• Hands-on experience on automotive airflow measurement with Torrington or similar devices
• Experience with CFD software and simulation (Element, Powerflow, StarCCM+, Fluent)
• Experience with 1D simulation tools such as GT Suite, Matlab / Simulink
• Excellent communication, interpersonal, and teamwork skills
• Must have a valid driver’s license in the state of residence that you will be driving/operating a vehicle

• Lead vehicle level thermal benchmark activities with a focus on front end design, AGS strategy, airflow, and thermal architecture
• Drive the overall integration of front-end and underhood thermal performance with stakeholders in Design Studio, Aerodynamics, Thermal Engineering, and Controls
• Establish front-end airflow targets using a deep understanding of thermal system architecture to ensure all charging and performance goals are met
• Interface with cross-functional teams to develop and align on coherent vehicle level AGS strategies to meet targets from all related vehicle attributes
• Be responsible for underhood thermal DVPs for both stationary and dynamic cases on both airflow volume and temperature requirements
• Conduct data analysis for vehicle level testing especially on ORFM airflow, temperature pickup, front end air-recirculation, etc.
• Work with cross-functional simulation teams to review 3D CFD and 1D vehicle simulation results
• Collaborate with 1D thermal simulation teams to further improve the accuracy of front-end heat exchanger performance
• Support vehicle level testing in wind tunnel
