No H1B

Responsibilities

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

Provide product support: manage releases, triage user reports, create guides, support sales demos, and assist marketing

Research and prototype: explore new modeling, simulation, and rendering techniques; take prototypes to production

Optimize performance and scalability: improve memory, threading, and large-scene workflows
