Fluid Dynamics Jobs (NOW HIRING)

About Rivian
Rivian is on a mission to keep the world adventurous forever. This goes for the emissions-free Electric Adventure Vehicles we build, and the curious, courageous souls we seek to attract.
As a company, we constantly challenge what's possible, never simply accepting what has always been done. We reframe old problems, seek new solutions and operate comfortably in areas that are unknown. Our backgrounds are diverse, but our team shares a love of the outdoors and a desire to protect it for future generations.
Role Summary
We are looking for a motivated Junior Fluid Dynamics Engineer to join our team and contribute to the aerodynamic development of our next-generation electric adventure vehicles. In this role, you will provide critical technical support to the aerodynamics team, moving from early-stage simulations to real-world production validation.
As an entry-level engineer, you will work under the guidance of Senior and Staff engineers to balance the demands of drag reduction, lift balance, and cooling requirements with the aesthetic vision of our Design Studio. This is a hands-on role where you will transform raw fluid-dynamics data into actionable insights that help define the efficiency and capabilities of our fleet.
Responsibilities

• Simulation & Analysis: Execute high-fidelity CFD campaigns across Aerodynamics, Soiling, and Water Management to optimize vehicle range and ensure the environmental reliability of autonomous sensor suites.
• AI-Driven Workflow: Leverage machine learning and advanced scripting to automate simulation post-processing, identifying performance patterns and drastically reducing turnaround times for complex physics.
• Design Strategy: Collaborate with the Design and Styling teams to provide data-driven feedback on surface development, balancing aesthetic intent with the technical requirements for water runoff and soil mitigation.
• Testing & Validation: Support both wind tunnel and environmental test programs (including water fording and soiling validation) to correlate digital models with real-world sensor performance and vehicle efficiency.
• Cross-Functional Integration: Partner with Autonomous Hardware, Thermal, and Range teams to ensure Aerodynamics & Environmental Performance targets are met within the broader context of vehicle development.
• Technical Communication: Synthesize complex fluid dynamics phenomena into actionable reports, providing clear guidance to senior leadership and cross-functional partners.

Qualifications

• Education: Bachelor's or Master's degree in Aerospace or Mechanical Engineering; a focus on fluid dynamics or aerodynamics is preferred.
• Experience: 0-2 years of experience (including internships or Formula Student/FSAE experience) in automotive or aerospace aerodynamics.
• Technical Skills: Foundational knowledge of commercial CFD codes and their application to fluid flow problems.
  • Familiarity with CAD software (CATIA V6 preferred) for surface manipulation and model preparation.
  • Strong Python or MATLAB skills for data analysis and workflow automation.
• Soft Skills: Strong communication skills and the ability to explain technical findings to a variety of stakeholders.
• Mindset: A "can-do" attitude with a proven track record of managing projects from concept to completion in a team environment.
• Ability to travel up to 20%.
