Up for helping to improve Ubuntu Linux and get it into shape for more gaming? Now is your chance, as Canonical are hiring exactly for that. They did say only recently that they were going "all in" with gaming on Ubuntu, when they announced their testing Snap package for Steam and of course there was more to come.
The new role mentions they are "seeking Software Engineers to join the Ubuntu Gaming Experience team and be part of our mission to ship the best open source operating system in the world". What the heck is this team anyway? Well, as they explain, they're hiring to create a team that is focused on "performance, compatibility and user experience for gamers".
People in this role will "work with open source projects like Proton and partners like Unity to improve the gaming experience for Ubuntu users around the world, as well as the wider Linux gaming ecosystem in general" — so it's a wide ranging job and it appears Canonical want to get people involved directly in improving the likes of Wine and Proton, Mesa drivers graphics drivers and more as you need to be "effective working with low-level libraries, drivers, and the Linux graphics, sound and input stacks".
The good news is that it's a remote position, so pretty much anyone with the experience needed can apply to improve gaming on Linux and Ubuntu for everyone.
