AI Simulation Engineer

Location: On-site in Metzingen / Riederich, Germany

Company

hirify.global' AI department develops simulation, synthetic data, and World Action Model capabilities for humanoid and collaborative robots.

What you will do

• Build scalable simulation and data generation pipelines for training and validating perception and policy models.
• Construct generated 3D scenes from real-world recordings, including assets, physically accurate materials, humans, and objects.
• Develop domain randomization strategies for lighting, textures, physics, sensor noise, and camera poses to improve sim-to-real transfer.
• Create methods for 3D inpainting and scene editing across 3D scenes and point clouds.
• Design and fine-tune generative World Action Models that predict scene dynamics, object interactions, and robot action consequences.
• Collaborate with AI, perception, control, and manipulation teams while integrating sensor models, diagnostic tools, documentation, and CI/CD processes.

Requirements

• Excellent Master's or PhD degree in Computer Science, Physics, Robotics, Computer Graphics, or a related field.
• 3+ years of relevant experience in scene simulation or compositing, synthetic data generation, 3D vision, or 3D augmentation.
• Strong programming skills in Python or modern C++.
• Hands-on experience with PyTorch or TensorFlow and generative models such as diffusion models, NeRFs, Gaussian splatting, or transformer-based world models.
• Solid background in computer graphics, 3D geometry, rendering pipelines, physical simulation, and procedural generation.
• Very good written and spoken English and willingness to work on-site in Germany.

Nice to have
