About The Position

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.

Requirements

• Bachelor’s or Master's degree in Aerospace or Mechanical Engineering; a focus on fluid dynamics or aerodynamics is preferred.
• 0–2 years of experience (including internships or Formula Student/FSAE experience) in automotive or aerospace aerodynamics.
• 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.
• Strong communication skills and the ability to explain technical findings to a variety of stakeholders.
• A "can-do" attitude with a proven track record of managing projects from concept to completion in a team environment.

Responsibilities

• Execute high-fidelity CFD campaigns across Aerodynamics, Soiling, and Water Management to optimize vehicle range and ensure the environmental reliability of autonomous sensor suites.
• Leverage machine learning and advanced scripting to automate simulation post-processing, identifying performance patterns and drastically reducing turnaround times for complex physics.
• 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.
• 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.
• Partner with Autonomous Hardware, Thermal, and Range teams to ensure Aerodynamics & Environmental Performance targets are met within the broader context of vehicle development.
• Synthesize complex fluid dynamics phenomena into actionable reports, providing clear guidance to senior leadership and cross-functional partners.
