Who We Are

Aurex is a mission-focused aerospace and defense company building the next frontier of deterrence. From hypersonics and missile defense to hardened networks and orbital systems, we design, test, and deliver the platforms that turn unproven ideas into battlefield-ready capability.

Born in Huntsville and built for speed, Aurex brings together aerospace veterans, combat-tested operators, and forward-leaning technologists to solve problems that matter—fast. We move from whiteboard to warfighter with precision, clarity, and zero tolerance for fluff.

Job Overview

As a Mechanical Engineer with CFD expertise, you’ll be at the forefront of turning ideas into high-performance, validated designs. Your simulations will guide critical engineering decisions—whether it’s reducing drag on a new aerospace component, improving thermal management in an electronics enclosure, or optimizing fluid flow in systems. Your work will directly influence product performance, cost efficiency, and sustainability outcomes.

What You'll Do

• Lead CFD simulations for projects involving fluid flow, heat transfer, and multiphase systems using tools like ANSYS Fluent, CFX, or STAR-CCM .
• Translate complex physical problems into accurate computational models, from geometry preparation to mesh generation and solver setup.
• Collaborate with design engineers to integrate CFD insights into CAD models and mechanical designs.
• Validate simulation results through experimental data, wind tunnel testing, or field measurements.
• Optimize designs for performance, manufacturability, and compliance with industry standards.
• Document methodologies, results, and recommendations in clear, client-ready reports.

What You'll Bring

• Bachelor’s or Master’s degree in Mechanical Engineering (or related field) with a focus on fluid mechanics or thermodynamics with 5 years of experience.
• Hands-on experience with CFD software (e.g., ANSYS Fluent, CFX, STAR-CCM , OpenFOAM).
• Strong understanding of turbulence modeling, heat transfer, and boundary conditions.
• Proficiency in CAD tools (e.g., SolidWorks) and geometry preparation for simulation.
• Ability to interpret and communicate complex simulation results to both technical and non-technical audiences.
• A problem-solving mindset with attention to detail and a passion for engineering excellence.

Why You'll Love It Here

• Work on diverse, high-impact projects across aerospace and defense sectors.
• Access to cutting-edge simulation tools, high-performance computing resources, and in-house prototyping labs.
• Development stipend for certifications, conferences, or advanced training.
• Flexible work arrangements, including hybrid schedules.
• Comprehensive health benefits, 401(k) with company match, and generous paid time off.
• A collaborative culture where your ideas are valued and your expertise makes a visible difference.
