About VinMotion

VinMotion is a humanoid robotics company under Vingroup, focused on building Motion Intelligence by combining AI, Robotics, and real-world deployment.
We are expanding our AI team to develop LLM and Multimodal AI systems powering human–robot interaction and autonomous task execution.

Responsibilities

• Design, develop, and optimize LLM-based systems for real-world applications (chat, instruction-following, task execution)

• Build and improve fine-tuning and alignment pipelines (SFT, RLHF, DPO)

• Work with multimodal models (text, vision, audio) for humanoid robots

• Develop RAG (Retrieval-Augmented Generation) systems with internal data

• Optimize model performance: latency, throughput, and cost (quantization, distillation)

• Deploy and maintain models in production (API, edge, cloud environments)

• Collaborate with Robotics, Perception, and Product teams to integrate AI into real systems

Requirements

• 3+ years of experience in Machine Learning / Deep Learning

• Hands-on experience with LLMs / NLP (transformers, fine-tuning, prompt engineering)

• Strong proficiency in Python and ML frameworks (PyTorch / TensorFlow)

• Solid understanding of modern LLM architectures (GPT, LLaMA, Mistral, etc.)

• Experience with

  • RAG systems (vector databases, embeddings, retrieval)

  • Model optimization (quantization, pruning)

  • Model serving (vLLM, Triton, FastAPI, or similar)

• Strong problem-solving skills with a data-driven mindset

Nice to Have

• Experience with multimodal models (VLM / VLA)

• Experience deploying models on edge devices or robotics systems

• Publications, open-source contributions, or strong project portfolio in AI

• Basic understanding of robotics / embodied AI

Why VinMotion

• Build AI for real humanoid robots, not just research prototypes

• Work with top-tier AI and Robotics engineers

• Solve challenging problems in real-world AI (physical environments)

• Opportunities for global collaboration and US assignments

• High-impact, fast-paced environment with strong ownership

Location

• Hanoi, Vietnam

• Opportunities for short-term or long-term assignments in the US

Compensation and Benefits

• Competitive package (13th-month salary and performance bonus)

• Meal allowance and holiday bonuses

• Global project exposure and visa support (if applicable)

• Fast-growing, high-tech environment
