Company

Riot Games develops and operates player-focused games, including League of Legends.

What you will do

• Author, extend, and maintain real-time shaders, reusable shader functions, and shared material systems for League of Legends champions, skins, and related content.
• Apply PBR principles across albedo, normal, roughness, metallic, ambient occlusion, emissive, lighting, and reflection inputs.
• Translate art direction and visual goals into robust, performant rendering solutions in collaboration with Art, Design, and Engineering.
• Support internal and external vendor artists with material and shader authoring, integration, troubleshooting, and production reviews.
• Validate assets across neutral lighting, around-game, and in-game environments while diagnosing lighting, shadow, material, shader, and texture issues.
• Profile shader and rendering costs, manage memory budgets, optimize performance with RenderDoc or equivalent tools, integrate vendor assets through Perforce, and maintain workflow documentation and scripts.

Requirements

• 4+ years of professional experience as a Technical Artist in game development or real-time graphics.
• Hands-on experience writing, debugging, and shipping shaders for a modern real-time PBR-based game engine.
• Ability to read, write, and debug HLSL and GLSL, plus node-based shader graphs or comparable proprietary systems.
• Strong skills in game modeling, shaders, texturing, and lighting, including stylized and hand-painted content pipelines.
• Proficiency with commercial or proprietary game engines such as Unity or Unreal, including GPU profiling, memory budgets, and optimization across hardware.
• Strong technical writing, communication, collaboration, and version-control skills with Git or Perforce. Legal authorization to work in Singapore without employer sponsorship is required.

Nice to have

• Experience with stylized PBR, toon/PBR hybrid, or other non-photorealistic rendering.
• Experience creating character-material shaders for skin, hair, cloth, or metal.
• Experience with material-driven systems, runtime parameters, VFX integration, gameplay-driven visual hooks, or Python tools and scripts.
• Familiarity with Maya, Photoshop, Substance, Marmoset Toolbag, 3D math, linear algebra, and color space.
• Experience supporting external vendors and familiarity with the League of Legends IP and stylized skin universes.

Culture & Benefits

• Collaborative work across Art, Design, Engineering, and external partners.
• Focus on player empathy, craft expertise, experimentation, and decision-making that prioritizes player experience.
• Portfolio with shader or material breakdowns is required for application.

Hiring process

• Submit a portfolio describing the role, engine or rendering framework, PBR inputs, lighting considerations, and performance or memory constraints addressed.
• An art test may be required during the application process.
