<p>We are looking for a Systems Engineer (Physics & Simulation) to build the high-fidelity physical foundation of our Digital Twin platform. You will be responsible for ensuring that our virtual environments — from turbulent sea states to complex airflow around urban infrastructure — adhere to rigorous physical laws. Working with NVIDIA Omniverse and Open Universal Scene Description (OpenUSD), you will bridge traditional engineering simulation with real-time interactive environments to support operational planning and decision-making.</p>
<ul data-pm-slice="3 3 []">
<li>
<p>Develop high-fidelity physics environments in NVIDIA Omniverse using OpenUSD, with a focus on maritime hydrodynamics and aviation aerodynamics.</p>
</li>
<li>
<p>Implement and tune rigid-body dynamics, fluid solvers, and multi-physics constraints to accurately replicate real-world asset behaviour.</p>
</li>
<li>
<p>Optimise complex mechanical and geospatial 3D assets — including vessels, aircraft, and infrastructure — for real-time physics computation without compromising accuracy.</p>
</li>
<li>
<p>Integrate ArcGIS GeoAI workflows to ingest geospatial data, converting 2D maps and 3D city layers into simulation-ready OpenUSD environments.</p>
</li>
<li>
<p>Apply spatial analysis techniques to define boundary conditions for physics simulations, such as coastal topography for wave impact modelling or urban canyon geometry for drone turbulence analysis.</p>
</li>
</ul>
