3D Geometry | Deformable Surfaces | Rendering | SimulationRole Overview
We are looking for a highly experienced Computer Graphics Engineer with deep expertise in 3D geometry, mesh processing, deformation, rendering and simulation.
The ideal candidate has worked on core computer graphics technologies or graphics-intensive products and is comfortable developing algorithms close to the geometry, rendering and simulation layers. Experience with game engines, digital humans, character systems, physics simulation or other complex 3D applications is highly relevant.
This is an engineering role requiring strong mathematical foundations and the ability to develop and optimize graphics algorithms rather than simply use existing 3D tools.
Key Responsibilities
- Design and implement algorithms for 3D mesh processing, deformation, warping and surface correspondence.
- Work extensively with triangular/polygonal meshes, mesh topology, parameterization, registration and remeshing.
- Develop techniques for deformable surfaces, including shape transformation, fitting, morphing and pose-dependent deformation.
- Work with texture coordinates, UV mapping, texture transfer/binding and texture deformation.
- Develop and integrate realistic material and rendering pipelines, including physically based rendering.
- Work with different surface/appearance representations such as albedo, normal, displacement, depth, roughness, specular and related maps.
- Develop solutions involving collision detection, proximity queries, surface interaction and physics-based deformation.
- Integrate and transform geometry originating from CAD, scanned or procedurally generated 3D models.
- Develop high-performance graphics algorithms using C++ and GPU/parallel computing.
- Work with real-time rendering and graphics technologies and optimize for performance, memory and visual quality.
- Collaborate with computer vision and ML engineers where 2D/3D data needs to be converted into or aligned with graphics representations.
Required Expertise
- Deep knowledge of Computer Graphics and 3D Geometry
- Strong understanding of:
- Linear algebra and 3D transformations
- Computational geometry
- Mesh topology and mesh processing
- Surface parameterization and correspondence
- Deformation and warping
- Rendering pipelines and shaders
- Physically Based Rendering (PBR)
- Strong C++ programming skills.
- Experience with one or more graphics APIs/technologies such as OpenGL, Vulkan, DirectX, Metal, CUDA or WebGPU.
- Strong understanding of GPU architecture, parallel algorithms and graphics performance optimization.
Highly Desirable
- Experience with cloth/deformable-body or physics simulation.
- Experience with FEM, PBD/XPBD, mass-spring systems or related numerical simulation techniques.
- Experience with collision detection, self-collision and contact handling.
- Experience with human/character models, skinning, rigging or pose-dependent deformation.
- Experience with CAD geometry, tessellation and CAD-to-mesh pipelines.
- Experience with texture baking, UV parameterization and texture transfer.
- Experience with Unreal Engine, Unity or a custom graphics/game engine, particularly at the engine/graphics level.
- Knowledge of computer vision, 3D reconstruction, point clouds, depth or 3D registration.
- Familiarity with Python, CUDA and shader programming (GLSL/HLSL).
Ideal Candidate
We are looking for someone who has built sophisticated 3D graphics systems, rather than someone whose primary experience is using 3D authoring tools.
Strong candidates may come from computer graphics, rendering, game-engine technology, physics simulation, computational geometry, digital humans, animation, CAD/CAE, AR/VR, VFX or 3D reconstruction.
A strong academic/research background in Computer Graphics, Computational Geometry, Simulation or related areas, including publications or contributions to graphics technologies, is a plus.
Experience: 7+ years in relevant Computer Graphics / 3D engineering roles; exceptional candidates with deep specialist expertise may be considered with fewer years.
