Staff Machine Learning Engineer, 3D - Singapore Efficiency Team

About Riot Games and the Role

Founded in 2006 by enthusiastic gamers, Riot Games has focused on creating player-centric game experiences, most notably with League of Legends, which attracts over 100 million monthly players worldwide. We are seeking highly skilled, humble, and innovative professionals passionate about gaming and game development to join our Singapore Efficiency Team.

This team develops advanced technology to streamline 3D content creation, specifically targeting the labor-intensive stages like cleanup, retopology, UV mapping, and level of detail (LOD) generation, to help artists produce polished game assets more efficiently. You will work under the Senior Manager of Machine Learning Engineering.

Key Responsibilities

• Develop assistive 3D tools using geometric algorithms, implicit representation methods such as Signed Distance Functions (SDF), Neural Radiance Fields (NeRF), Gaussian splatting, as well as neural rendering and UV/texturing technology to speed up artistic workflows including cleanup and retopology.
• Collaborate closely with 3D modelers and environment artists to identify and target the most time-intensive modeling, retopology, and texturing tasks and deliver tools that substantially reduce these efforts.
• Design and implement evaluation criteria for assessing 3D outputs concerning geometric precision, topology quality, and readiness for game integration, while quantifying the efficiency gains delivered to artists.
• Keep abreast of new research and developments in 3D machine learning and neural rendering, critically evaluating their suitability under production and runtime constraints.

Required Qualifications

• Master’s or Ph.D. in Computer Science, Statistics, Mathematics, or related fields concentrating on machine learning, data science, or artificial intelligence.
• Extensive, specialized expertise in 3D machine learning, including mesh and geometry processing, implicit representations (SDFs, NeRF, Gaussian splatting), point cloud learning, neural rendering, and differentiable rendering techniques.
• Minimum of five years applying machine learning to practical, real-world 3D problems, with proven experience delivering impactful full-cycle ML solutions in a fast-paced setting.
• Record of contributing to cutting-edge techniques, demonstrated by publications in prominent conferences like SIGGRAPH, CVPR, ICCV, ECCV, or NeurIPS, or through completed projects, open-source contributions, or deployed production systems pushing 3D technical frontiers.
• Proficiency in programming languages such as Python, C, C++, or C#, along with hands-on experience using machine learning frameworks including PyTorch, TensorFlow, or JAX.
• A strong foundation in statistical analysis, experimental methodology, and result evaluation.
• Deep practical experience with generative models such as 3D-aware diffusion models, flow matching models, and variational autoencoders applied to meshes, point clouds, or implicit data for creating artist-assistive tools and optimizing technical 3D workflows.
• Exceptional communication skills to convey complex technical concepts effectively to a non-technical audience.
• Leadership capabilities including mentoring junior engineers and interns, and fostering cross-team collaboration are highly valuable.

Preferred Qualifications

• Background or experience working within the gaming industry or a similar sector is advantageous.

Success Factors

Success in this position hinges on a blend of deep technical mastery, collaborative mindset, and a commitment to player satisfaction. We value your technical background, prior accomplishments, and genuine passion for gaming, especially your empathy towards player experiences.

Benefits and Perks

• Comprehensive relocation support to Singapore.
• Complete health insurance coverage for you and your family, including spouse and children.
• Flexible paid time off policy.
• Retirement plan featuring company-matched contributions.
• Life insurance, parental leave, and both short-term and long-term disability benefits.
• Access to a Play Fund designed to deepen engagement with our player community through games.
• Matching support for your charitable contributions of both time and money to nonprofit organizations.
