Role
Who you are
- We’re looking for PhD candidates passionate about the intersection of computer vision, graphics, and generative modeling
- Possessing or pursuing a PhD in computer science, engineering, or a related field, with a thesis aligned to Roblox’s research areas
- Expertise in one or more areas: computer vision, multimodal learning, 3D Graphics, or large-scale representation learning
- Experience developing and training deep learning models using modern frameworks (PyTorch, TensorFlow, JAX)
- A strong research track record, evidenced by multiple publications and presentations in top-tier, peer-reviewed venues
- Proficiency in one or more programming languages (e.g., Python, C++, Go, Java) and experience building and optimizing large-scale systems
What the job involves
- At Roblox, computer vision and graphics power the way our global community discovers, creates, and interacts on our virtual platform
- This role involves building cutting-edge models to interpret and analyze every form of content—experiences, text, images, videos, and 3D avatars
- Your work will directly influence core systems that drive the next generation of creation, search, recommendations, and trust & safety initiatives across our massive ecosystem
- You’ll work on applied research and engineering projects with direct production impact — enabling new ways for creators and players to bring ideas to life
- Teams Hiring for This Role:
- Content Understanding: Develop large-scale computer vision and multimodal models that classify, organize, and recommend 3D and visual content to improve user discovery, personalization, and safety
- Account identity : focuses on various aspects of user Identity from bot detection, alternate account detection graph, to age estimation based on behavioral and facial features
- You Will:
- Lead the research and development of deep learning models for visual content understanding and 3D content generation (image/video/3D scenes, avatars, and assets)
- Design and implement foundation models for visual and 3D-based creation, search, and recommendations, ensuring a high level of fidelity, relevance, and ranking
- Break down complex product requirements into iterative deliverable stages, moving applied research into high-scale production systems
- Implement innovative visual and multi-modal models that power core Roblox functions (e.g., world creation, avatar systems, search, and recommendations)
- Build high precision facial age estimation across demographics from ground up including various fraud detection techniques for a robust and safe user identity system
Our take
Online gaming may be a well-established space, but Roblox has distinguished itself as a leader by empowering its community to build, share, and profit from their own creations, turning game development into an accessible, rewarding ecosystem for millions of users.
In addition to standard games, the platform offers virtual worlds and other experiences to explore and interact with. Its platform provides an online ecosystem for millions to create, socialize, chat, and explore immersive experiences with friends. In fact, in the US its used by two-thirds of children aged 9 to 12.
While the platform does face scrutiny over users safety (particularly given its young audience) the company's efforts to strengthen parental controls and open dialogue through initiatives like its new Parents Council signal a growing commitment to addressing these challenges. At the same time, its financial performance and creator-focused investments underscore a business in very strong health. With record payouts to developers, an expanding older player base, and a platform that increasingly rewards creative talent, Roblox's trajectory remains one of innovation and impressive growth.
