NVIDIA's new job listings suggest it's looking to strengthen its Linux efforts, including roles focused on Vulkan graphics optimization and Linux graphics engineering in general. You may have also heard Vulkan pretty recently, as Mojang is switching from OpenGL to Vulkan for the Java edition of Minecraft.
Basically, Vulkan is a modern graphics API that acts as the backbone of most advanced graphics work on PC games, just like Microsoft's DirectX. It allows games to communicate efficiently with your graphics card, giving developers more direct control over performance.
