Responsibilities
Build a learned world model of the welding process that predicts future system behavior under robot actions
Develop multimodal neural simulators incorporating signals such as 3D scans, video, thermal data, and electrical measurements
Design, train, and evaluate large-scale generative or dynamics models (e.g., video prediction, latent world models, 3D or spatiotemporal representations) capable of long-horizon rollouts
Collaborate with reinforcement learning engineers by integrating the neural simulator into RL pipelines for policy training and evaluation
Run research tracks in parallel with production development, including hypothesis-driven experimentation and ablation
Partner closely with data and MLOps teams to support scalable training, evaluation, and deployment - while remaining comfortable owning pieces of the stack when needed
Translate research prototypes into robust, maintainable production code when they prove valuable
Validate simulator performance against real-world robotic welding data and support sim-to-real transfer
Qualification
Required
Experience building and deploying ML systems for robotics or other complex physical processes in real-world settings
Hands-on experience with world models, learned simulators, video generation, 3D modeling, or dynamics prediction
Comfortable training large models from scratch and working with the tooling and infrastructure required to scale experiments
Enjoy working with messy, real-world data and are pragmatic about imperfect ground truth
Strong software engineer with solid Python skills and experience in frameworks such as PyTorch or JAX
You are excited by a role that blends research depth with practical impact, and you're willing to context-switch when the team needs it
