Research Engineer, Simulation & World Models

Mecka AI is seeking a Research Engineer to build and scale simulation systems for training and evaluating robots and embodied AI. You will develop highly realistic simulation environments, improve physical fidelity, and create learned or hybrid world models to bridge the gap between simulation and real-world robotics.

• Build and debug physics-based simulation environments using MuJoCo, Isaac Sim, or similar
• Develop scalable pipelines for parallel rollouts, synthetic data generation, and policy training
• Improve physical fidelity by calibrating against real-world data and identifying model mismatches
• Drive sim-to-real transfer through system identification and domain randomization
• Develop learned or hybrid world models for prediction, planning, and control
• Strong Python and C++ systems skills for building reproducible research tools
