Senior Robotics Engineer - Simulation

We are looking for a Senior Robotics Engineer - Simulation to design and develop high-fidelity simulation environments and digital twins for autonomous underwater vehicles (AUVs). The ideal candidate will have strong expertise in robotics simulation, physics-based modelling, ROS2 integration, and C++ development, with experience in simulation platforms such as NVIDIA Isaac Sim, Unreal Engine, or Unity.
Responsibilities:
Develop high-fidelity marine simulation environments using NVIDIA Isaac Sim (preferred), Unreal Engine, Unity, or custom simulation frameworks.
Model realistic ocean conditions, including currents, waves, buoyancy, hydrodynamics, turbidity, thermoclines, and underwater acoustics.
Build accurate vehicle dynamics models, including 6-DOF motion, thruster interactions, drag, lift, added mass, and buoyancy.
Develop realistic sensor simulations for sonar (forward-looking, side-scan, multibeam), DVL, IMU, cameras, LiDAR, and acoustic modems.
Create digital twin infrastructure for autonomous underwater vehicles.
Integrate simulation environments with ROS2-based autonomy stacks for SIL and HIL testing.
Design scalable simulation pipelines supporting Monte Carlo simulations and automated regression testing.
Validate simulation results against real-world testing data.
Optimise simulation performance using GPU acceleration and parallel computing.
Collaborate with autonomy, perception, controls, and embedded engineering teams.
Requirements:
Bachelor's/Master's/PhD in robotics, computer science, mechanical engineering, game development, or a related discipline.
5-8 years of experience in robotics simulation, digital twin development, or physics-based simulation.
Strong programming skills in C++.
Hands-on experience with NVIDIA Isaac Sim (preferred), Unreal Engine, Unity, and custom simulation engines.
Experience with ROS/ROS2 integration.
Strong understanding of rigid body dynamics, hydrodynamics, fluid dynamics, and sensor modelling.
Experience with Software-in-the-Loop (SIL) and Hardware-in-the-Loop (HIL) testing.
Strong mathematical knowledge of linear algebra, physics, and numerical methods.
