  • Build and maintain tooling related to 3D content processing, geometry, scene preparation, wall generation, model conversion, and other math-heavy tasks;
  • Research and evaluate current and upcoming technologies related to 3D, rendering, media formats, data processing, and production automation;
  • Write maintainable, high-performance, and high-quality code using best practices, SOLID principles, automated tests, code reviews, and clean architecture.
Required knowledge of:
  • Strong experience with Java and/or Kotlin on JVM;

  • Import and export of 2D/3D data from and to .dxf/.dwg/.blend formats;
  • Write a Blender plugin to load data and provide additional modeling functionality;
  • Write high performance code using CPU and GPU to the max (using parallel, concurrent programming like coroutines, threads, Rx, promises, futures, etc.);
  • Build processing pipelines, where multiple threads are used to max out CPUs and do lots of different processing on multiple threads/coroutines/Rx/java streams/etc.
