Senior Software Engineer

The opportunity
At SpeedTree (a division of Unity Technologies) we help studios bring natural worlds to life. We build industry-leading tools and runtimes for modeling animating and rendering vegetation across games film and real-time experiences. Our technology powers artist-friendly creation real-time performance and seamless pipeline integrationfrom DCCs to game enginesso teams can ship beautiful scalable worlds faster. At our core were passionate about visuals performance and giving creators the tools they need to make nature believable.

We are looking for a Senior Software Engineer who shares our passion for games and visual effects. As a key member of the team your role will include designing and implementing advanced vegetation modeling tools that empower artists and technical users building and optimizing real-time graphics features for believable performant foliage across platforms and providing end-to-end support for games and VFX pipelines.

What youll be doing

• Extend the modeling system: add new 3D modeling features tools and parametric controls for vegetation.
• Build GUI features: create clean fast interfaces and widgets for modeling materials LODs wind and export.
• Improve in-app rendering: enhance real-time shading lighting wind and LOD for accurate WYSIWYG previews; profile and optimize.
• Evolve the export pipeline: support more targets and formats; handle materials LODs instancing collisions impostors and metadata; automate and validate.
• Integrate with pipelines: develop plugins/bridges for DCCs and engines; ensure consistent materials units and animation/wind data.
• Ensure quality: write modern C/GPU code add tests document features and review code.
• Collaborate cross-functionally: partner with artists TDs and integrators to gather requirements and resolve issues.

What were looking for

• Strong C (modern C17/20 STL templates debugging profiling)
• Graphics API experience (OpenGL required; Vulkan/DirectX a plus)
• GPU programming basics (GLSL/HLSL shaders render pipelines performance)
• 3D math and geometry (linear algebra transforms curves/surfaces normals/UVs)
• Practical 3D modeling exposure (DCC tools topology materials LODs; not an artist but understands workflows)
• Real-time rendering fundamentals (lighting PBR shadows transparency normal/tangent spaces)
• Tool/UI development experience (Qt/ImGui or similar; custom widgets viewport tooling)
• Cross-platform development (Windows/macOS/Linux) and build systems (CMake)
• Source control and CI (Git code review automated builds/tests)
• Pipeline/format familiarity (FBX/OBJ/GLTF textures metadata; game/VFX engine integration a plus)
