Across our global network, LG employees share a common mission: to bring the Life’s Good promise to our customers by creating a better life for people, and a better future for our planet through our smart life solutions. Our relentless drive for innovation, combined with our culture of challenge and change, enables us to lead in today’s dynamic market.

At LG, Life’s Good.

LG Toronto AI Lab is looking for a Sr. Physical AI Research Scientist who will contribute to designing and developing robot agents that operate safely and robustly in the real world. This role focuses on advancing physical intelligence agents that perceive, reason, and act under real-world constraints, while explicitly addressing safety, uncertainty, and reliability, which are key priorities for LG Electronics as a leading global corporation in the design and development of robotics systems (from industrial and home robots to humanoids).

Requirements

Our mission is to develop safe robotic agents that robustly align their actions with high-level intent, environmental constraints, and safety requirements, even under uncertainty in open-world settings. In this role, you will contribute to:

• Robot Safety Architecture: Design and implement safety verification and monitoring modules within the robot agent architecture
• Safety and Generalization: Develop methods to improve the safety, robustness, and generalization of robotic foundation models, including vision-language-action (VLA) models and world models
• Scaling via Simulation: Build and maintain large-scale simulation frameworks leveraging generative models and domain randomization to enable scalable robot learning
• Continual Learning: Develop safe exploration and continual learning approaches that enable physical agents to adapt to unstructured environments while respecting strict safety constraints
• Simulation-to-Reality Transfer: Develop scalable, safety-critical simulation pipelines to rigorously evaluate and stress-test robot agents prior to real-world deployment

You will collaborate with researchers and engineers across multiple teams within the organization to build agents that are not only capable, but also safe, reliable, and robust in real-world environments.

Principal Responsibilities

• Quickly turn research concepts into practical, validated implementations
• Contribute to data collection strategies and training pipelines
• Develop imitation learning, reinforcement learning, and/or multimodal learning algorithms
• Fine-tune robotic foundational models, including but not limited to VLMs, VLAs and world models
• Design safety-aware robotic manipulation solution via including but not limited to fine-tuning, policy steering, and Best-of-N sampling
• Develop methods for Sim-to-real transfer, data-efficient learning (offline RL, self-supervised learning), robustness to noise and distribution shift
• Collaborate with Physical Intelligence, Embodied AI, and Robotics teams across the organization to develop prototypes and deploy models on physical robots
• Support and contribute to R&D collaborations with academic and industry partners
• Mentor junior team members and contribute to research direction
• Additional duties as assigned

Knowledge, Skills, And Abilities

• Education and Professional Experience
• PhD in Machine Learning, AI, Robotics, or related fields with 3+ years of post-graduate R&D experience, OR
• M.Sc. in ML/AI/Robotics with 6+ years of experience
• Strong publication in top-tier conferences or journals (incl., NeurIPS, ICLR, CVPR, CoRL, ICRA) related to Computer Vision, Continual Learning, Reinforcement Learning, and Robotics
• General Technical Skills
• Strong foundation in natural language processing (NLP), computer vision, reinforcement learning (RL), and robotics
• Deep expertise in GenAI foundation models, including but not limited to multimodal large language models (MLLMs), vision-language models (VLMs), diffusion and flow matching models
• Hands-on experience with constitutional AI, alignment, optimization, and reward modeling/shaping
• Knowledge of transfer learning, meta learning, and contrastive learning is a plus
• Proven ability to design, execute, and rigorously evaluate experiments in complex ML/AI systems
• Strong proficiency in PyTorch and/or JAX
• Preferred Technical Skills
