Senior Robotics Engineer - Digital Twin

Job Summary:

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 modeling, ROS2 integration, and C++ development, with experience in simulation platforms such as NVIDIA Isaac Sim, Unreal Engine, or Unity.

Key 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 :

1. Sonar (Forward Looking, Side Scan, Multibeam)

2. DVL

3. IMU

4. Cameras

5. LiDAR

6. 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.

- Optimize simulation performance using GPU acceleration and parallel computing.

- Collaborate with autonomy, perception, controls, and embedded engineering teams.

Required Qualifications:

- Bachelor's/Master's/PhD in Robotics, Computer Science, Mechanical Engineering, Game Development, or related discipline.

- 5 to 8 years of experience in robotics simulation, digital twin development, or physics-based simulation.

- Strong programming skills in C++.

- Hands-on experience with:

1. NVIDIA Isaac Sim (Preferred)

2. Digital Twin

3. Gazebo

4. Robotics operating system
