- Have strong C# development experience

As with all other departments, we primarily look for experienced game industry professionals with a strong portfolio demonstrating work on shipped video game projects.

Remote Work

Although our headquarters are located in Prague, Czech Republic, our team works fully remotely from many different countries around the world.

However, we are generally only able to consider candidates whose time zones allow for a reasonable overlap with Central European Time (CET), enabling effective collaboration with the rest of the team.

General Information

We are always interested in hearing from experienced game developers who enjoy solving difficult problems, taking ownership, pushing their craft forward, and helping us build the next generation of [Space Engineers.](https://www.spaceengineersgame.com/)

Please note that experience outside the video game industry is generally not sufficient for most of our roles.

## Products & Services
- **Space Engineers** (2013–2019): A sandbox game about engineering, construction, and maintenance of spaceships and stations using volumetric physics and destructible environments. Sold over 5 million copies ([keenswh.com/careers](https://www.keenswh.com/careers/)).

## Market Standing
- **Valuation / Market Cap**: Not publicly disclosed (privately held)
- **Key Metric**: *Space Engineers* has sold more than 5 million copies as of 2025; the Steam Workshop hosts over 500,000 community creations ([keenswh.com/careers](https://www.keenswh.com/careers/)).

## Competitive Advantages
- **Proprietary VRAGE engine**: Fully owned technology that enables unique physics-based destruction, volumetric water (VRAGE3), and large-scale multiplayer simulation – hard to replicate.
