CrazyGames | https://about.crazygames.com/ | REMOTE (in Europe) | Full-time | Multiple roles

With recent technologies such as WebGPU and WebAssembly, the browser is quickly becoming a powerful gaming platform. High-quality 3D graphics and near-native level performance are becoming possible without the need for downloads, apps, or platform-specific development. Our browser games platform is already reaching more than 40 million people per month. We are self-funded, profitable, remote-first, and fast-growing.

We are currently looking for multiple people to bring our product, engineering, and adops to the next level.

Please note that we're looking for people who can work on a European timezone and are ideally based in Europe (which includes the UK for those in doubt).
