Senior Multimodal AI Researcher for Games & Agents

L&Q OASIS PTE. LTD.; Singapore; On-site; SGD 180,000 - 240,000; Full time

Job summary

Tencent's Lightspeed Tech Center seeks a Senior Researcher in multimodality to advance multimodal foundation models and agentic AI in gaming. You will explore multimodal understanding, post-training, and agent research, shaping research directions and deploying solutions at scale within Tencent's game products.

You will lead experiments end-to-end, publish in top venues, and collaborate with engineers to bring prototypes to production, influencing games across platforms.

Qualifications

• PhD in Computer Science, ML, or a related field, or equivalent research experience.
• Expertise in one or more of: multimodal understanding and vision-language reasoning; pre-/post-training of LLMs/VLMs; reinforcement learning and LLM-based agents; representation learning.
• Consistent first-author publications at leading venues (NeurIPS, ICML, CVPR, ACL, etc.).
• Strong implementation skills in modern ML frameworks (PyTorch, JAX, etc.).
• Proven ability to run complex experiments, analyze results, and iterate quickly.

Responsibilities

• Pioneer new research directions in multimodal understanding, post-training, reasoning, grounding, and agent planning, grounded in real gaming scenarios.
• Abstract research problems from game business scenarios, solve them, and land solutions that serve diverse in-game applications.
• Advance the understanding capabilities of multimodal large models (VLMs/MLLMs) across images, video, text, and audio.
• Lead post-training methodologies — SFT, RLHF/RLAIF, reward modeling, and preference alignment — to improve model capability and reliability.
• Design and execute experiments end-to-end: from data and benchmarking, to training, evaluation, and iteration.
• Collaborate with engineers to bring research prototypes into production and deploy them across game scenarios at scale.
• Publish at top-tier conferences and contribute to the broader research community.
