Rivian • Irvine, CA

78d • $154,000 - $192,500

About The Position

As a Staff Thermal Attributes Engineer, you will be the subject matter expert driving the complete lifecycle of vehicle thermal attributes, from initial target setting through final vehicle sign-off. Your deep technical expertise in thermal management systems, particularly heat pump operations and efficiency optimization, will be crucial in achieving performance goals. You will leverage strong analytical skills, including advanced simulation and data analysis, and a collaborative mindset to lead the development and execution of robust thermal attribute arbitration strategies. Your work will ensure performance targets are met and validated through vehicle program milestones and final Design Verification Plans (DVPs). This role is pivotal in fostering cross-functional alignment and resolving complex engineering challenges related to vehicle level thermal performance and efficiency.
