Julien Amsellem
Summary
🤩
RockstarJulien Amsellem is a senior software engineer based in the Greater Paris area with a strong track record building tooling and 3D-focused applications across games, photography, robotics and simulation. With roots in C++, C# and Python and an engineering degree from ESIEA, he’s shipped production UI, engine and pipeline features at Unity, Ubisoft and DxO and led teams building complex plugin-based editors and real-time simulators. He brings over a decade of Agile practice and a knack for UX-driven tooling—recently contributing UI and usability improvements to Unity’s high-profile Graphics repository (VFX graph editor). Julien combines low-level algorithm and computer vision experience with front-end polish, and often bridges art and engineering to make technical workflows more usable. He’s equally comfortable architecting extensible systems and diving into nitty-gritty bug fixes that improve day-to-day developer experience.
