Role brief

Growth Roles summary, based on the employer's posting.

What you'll do

Assess whether generated videos capture meaning, objects, relationships, and spatial structure
Build state-tracking and consistency models for generated video
Develop combined generation-and-understanding systems with fast feedback for interactive use
Study causal and physical controls for action-driven video with Agent/RL teams
Test interactive game capabilities, create evaluations, and shape technical roadmaps from industry research

What you bring

A Ph.D. in an AI-related field such as video understanding, prediction, reinforcement learning, or multimodal modeling
Strong knowledge of video-generation and VLM internals, including diffusion principles
Research experience with interactive or controllable video generation
Strong engineering ability to design complex training workflows using Python and PyTorch, plus relevant publications

Who this fits

You’ll fit a research-focused role centered on video models, interactive generation, and closed-loop control. Experience with Game AI, simulation environments, or similar systems is preferred, as are publications in leading conferences or journals. This is a full-time position based in Singapore at CapitaSky.

From the employer

Business Unit

LIGHTSPEED STUDIOS is made up of passionate players who advance the art & science of game development through great stories, great gameplay, and advanced technology. We are focused on bringing next generation experiences to gamers who want to enjoy them anywhere, anytime, across multiple genres and devices.

About the Hiring Team

Lightspeed Tech Center is a R&D department under Lightspeed Studios which develop PUBG Mobile and other high-quality games. Our Tech Center leads the research, exploration, and discovery of innovative technologies and provides technical services for all games during all phases of life cycle, including engine, audio, QA, AI, next generation game, technical cooperation, etc.

What the Role Entails

Research the model's ability to understand generated content, parsing semantics, objects, relationships, and spatial structures.
Implement state tracking and consistency modeling for generated videos.
Explore "unified generation-understanding" model architectures.
Research causal consistency control and physical constraints for the "action input → video output" pipeline.
Research hybrid architectures to achieve low-latency feedback for real-time interactive generation.
Collaborate with Agent/RL teams to drive an end-to-end closed loop of "generation → understanding → control → feedback."
Validate controllable interactive capabilities in game scenarios and lead the establishment of evaluation systems.
Continuously track industry-related work and formulate proprietary technical roadmaps.

Who We Look For

Ph.D. in AI-related fields, covering areas such as video understanding, video prediction, reinforcement learning, or multimodal generation and understanding.
Deep understanding of the internal mechanisms of both video generation and VLM models; familiar with diffusion model principles.
Research experience in interactive video generation or controllable video generation.
Ability to independently design complex model training pipelines with strong engineering skills.
Proficient in Python/PyTorch, with publications in video understanding, controllable generation, or reinforcement learning.
Experience with Game AI, simulation environments, or closed-loop systems is preferred.
Relevant publications in top-tier conferences or journals are preferred.
