Research Engineer, Simulation & Models

Mecka AI is building the data infrastructure layer for robotics and embodied AI.

Mecka AI is building the data infrastructure layer for robotics and embodied AI.

We design and operate global systems for data capture, data labeling, and hardware-enabled workflows used by leading AI labs and robotics companies to train and validate humanoid and embodied AI systems.

We work closely with frontier robotics teams to bridge real-world data, simulation, learning-based systems, and deployed hardware.

Build simulation systems that train and evaluate robots and embodied agents. Model physical interactions, create scalable training worlds and connect simulation with real-world data across Mecka Labs. This is a hands-on research engineering role for someone exceptional in simulation, physics and learning. You'll work with Mu Jo Co , Isaac Sim and related tools, close sim-to-real gaps, and build learned or hybrid world models for prediction, planning and control.

You own whether the simulated world behaves credibly and runs at scale; partner roles turn it into trainable tasks and reliable evaluations.

• Build simulation environments:
  Model robots, sensors, objects, contacts, materials and dynamics, with scenarios grounded in real behavior.
• Scale training workloads:
  Build reliable pipelines for parallel rollouts, synthetic data, policy training and evaluation.
• Improve physical fidelity:
  Calibrate against measured data, find mismatches in dynamics or sensing and make targeted improvements.
• Drive sim-to-real:
  Use system identification, domain randomization and controlled experiments to improve transfer.
• Develop world models:
  Build learned dynamics or latent models, combine them with physics-based systems and test their value for prediction, planning and control.
• Build with the team:
  Turn prototypes into reusable simulation assets, training infrastructure and documented methods with researchers and engineers.

• Simulation and physics:
  Deep experience building and debugging physics-based simulation with Mu Jo Co , Isaac Sim or comparable platforms.
• Robotics learning:
  Strong reinforcement learning and embodied AI fundamentals, including observations, actions, rewards and policy evaluation.
• World models:
  Experience with learned dynamics, latent world models or hybrid physics-learning systems.
• Research engineering:
  Strong Python and C++ systems skills; you build scalable, reproducible tools other researchers can extend.
• Experimental judgment:
  Design controlled experiments, measure sim-to-real gaps and trace failures to models, data, policies or infrastructure.

• Simulation or training infrastructure used at scale by a robotics or embodied AI research team.
• Demonstrated sim-to-real transfer in manipulation, locomotion, navigation or another physical domain.
• Published or open-source work in world models, differentiable simulation, GPU-accelerated simulation or model-based reinforcement learning.

Studies show women and candidates from underrepresented groups often only apply when they meet 100% of the listed qualifications, while others apply after meeting 60%. If you don't check every box above but believe you can do the job, we encourage you to apply — we're looking for capability and trajectory, not a perfect checklist match.
