Senior Multimodal AI Researcher for Gaming

LightSpeed Studios; Singapore; On-site; SGD 180,000 - 300,000; Full time

Job summary

LIGHTSPEED STUDIOS is seeking a Senior Researcher in multimodality to shape the next generation of foundation models and agentic AI for gaming. You will lead AI research focused on in-game contexts, abstracting business problems into deployable solutions and driving breakthroughs at scale.

Collaborate with engineers to productionize research prototypes, publish at top-tier conferences, and advance multimodal understanding across images, video, text, and audio.

Qualifications

• PhD in Computer Science, ML, or a related field.
• Expertise in multimodal understanding and vision-language reasoning; pre-/post-training of LLMs/VLMs; reinforcement learning and LLM-based agents; representation learning.
• Ability to abstract research problems from real business (gaming) scenarios and drive deployment.
• Consistent first-author publications at 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.
• Passion for high-impact research with real-world applications.

Responsibilities

• Shape the next generation of multimodal foundation models and agentic AI within gaming scenarios.
• Focus on AI research and applications for in-game contexts—abstracting research problems from real game business scenarios, solving them, and deploying solutions that serve a wide range of gaming use cases.
• Work on multimodal understanding, post-training, and agent research, driving breakthroughs that advance both the scientific frontier and Tencent's game products at scale.
• 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.
