Principal Rendering Programmer at Epic Games
Copenhagen, Capital Region of Denmark
Summary
🤩
Rockstar🎓
Top SchoolRune Stubbe is a Principal Rendering Programmer with 19 years of experience specializing in real-time rendering, low-level CPU/GPU optimization, and data compression. He has driven core graphics features across major engines—most recently contributing to Nanite at Epic Games—and has a track record of shipping tiled lighting, advanced shadowing, material systems, and platform-specific optimizations. Rune’s background includes work at Unity where he improved the Unity.Mathematics library used by Burst, adding matrix operations and tests, and earlier roles where he ported consoles to browser/OpenGL ES and built custom lossless compression for textures. Equally comfortable architecting high-level features and hand-tuning low-level implementations, he brings a performance-first mindset to complex rendering problems. Based in Copenhagen with a master’s in computer science from Aarhus Universitet, he combines production-grade engine experience with practical open-source contributions that improve math and shader workflows.
