Dear Candidate,

Greetings from Quest Global!

We have a great opportunity for you, please find the details below.

Location Base Location Hyderabad (Japan)

Experience- 4 to 9 Years

Job Requirements

We are looking for a Digital-Twin and Robotics Simulation Engineer to build and maintain the simulation-first pipeline for a humanoid robotics program. The role centers on building high-fidelity digital twins in NVIDIA Omniverse / Isaac Sim, generating synthetic data, and supporting policy training and validation for a humanoid robot before it is deployed on physical hardware. Candidates with a strong real-time 3D / simulation background (Unity, Unreal Engine, or similar, using C++/C#) who have since transitioned into the NVIDIA Omniverse / Isaac ecosystem are strongly preferred.

ROLES & RESPONSIBILITIES

- Build and maintain physically accurate digital twins of robot platforms on OpenUSD using NVIDIA Omniverse and Isaac Sim.
- Set up scenes, sensors, physics properties, and environment randomization for synthetic data generation using Isaac Lab / Cosmos world models.
- Support training and post-training of foundation-model robot policies (e.g., Isaac GR00T-class VLA models) by preparing simulation-ready datasets and trajectories.
- Develop Python-based tooling and pipelines to automate scene generation, domain randomization, data export, and simulation-to-training hand-off.
- Integrate Omniverse / Isaac Sim outputs with ROS 2 nodes, middleware bridges, and downstream AI training workflows.
- Work with the embedded / MCU team to align simulation timing, sensor models, and control interfaces with hardware-in-the-loop (HIL) requirements.
- Validate simulation fidelity against real robot behavior and iterate on physics tuning, sensor noise models, and scene accuracy.
- Collaborate with 3D content, AI/ML, and embedded engineers to keep digital assets, physics rigs, and policies in sync across the pipeline.
- Document simulation architecture, pipelines, and configuration for reuse across future robot programs.
- Participate in Agile ceremonies,



sprint planning, and technical design reviews.

Work Experience
- Bachelor's or masters degree in computer science, Robotics, Computer Engineering, or a related field.
- 4-9 years of software / simulation engineering experience, including current hands-on work with NVIDIA Omniverse and Isaac Sim.
- Working experience with Isaac Lab, Isaac GR00T, and/or NVIDIA Cosmos world models (or clear ability to ramp up quickly on these).
- Strong Python scripting skills for simulation automation, data pipelines, and tooling.
- Solid foundation in 3D graphics, physics-based simulation, and real-time rendering concepts.
- Prior professional experience with Unity3D or Unreal Engine using C++ and/or C# this real-time engine background, later transitioned into NVIDIA Omniverse/Isaac, is a strong plus.
- Understanding of USD (Universal Scene Description) based workflows and asset/scene pipelines.
- Familiarity with robot description formats (URDF/USD physics articulation) and basic robotics concepts (kinematics, sensors, actuators).
- Experience with version control (Git), Agile development, and cooperative engineering practices.
- Good communication and documentation skills; comfortable working with cross-functional AI, embedded, and simulation teams.

DESIRED / GOOD-TO-HAVE SKILLS
- Exposure to synthetic data generation, domain randomization, and dataset annotation for AI/ML model training.
- Familiarity with ROS/ROS2 middleware and robot control stacks.
- Experience with GPU-accelerated reinforcement learning or imitation learning workflows.
- Exposure to humanoids, AMR, AGV, or robotic-arm simulation projects.
- Knowledge of sensor simulation (LiDAR, depth cameras, IMU) within Omniverse/Isaac Sim.
- Understanding of sim-to-real transfer challenges and techniques.
- Familiarity with cloud/on-prem GPU compute environments for large-scale simulation and training.

DOMAIN EXPERIENCE
- Digital Twin & Simulation Platforms
- Robotics / Humanoid Systems
- NVIDIA Omniverse / Isaac Ecosystem
- Synthetic Data Generation for AI/ML
