At Keen Software House, we develop large-scale sandbox simulation games like Space Engineers 1 and Space Engineers 2, built around engineering, construction, destruction, physics, emergent gameplay, and player creativity, together with the proprietary technology that powers them. We are looking for a Senior UX Designer with professional experience in the video game industry to join our international team working across Space Engineers and Space Engineers 2.
Space Engineers is a complex sandbox game built around engineering, construction, exploration, survival, and player creativity. That complexity is part of what makes the game unique - but it also creates significant UX challenges.
Because we are a relatively small team, we are looking for a hands-on and versatile UX Designer who can contribute beyond UX theory, wireframes, and documentation. Strong UX expertise is the foundation of the role, but ideally you also bring visual/UI design skills or, alternatively, experience with technical UI prototyping, integration, or implementation.



Visual/UI design is particularly valuable for us given the current composition of the team.
You will work closely with Game Design, Art, Engineering, Production, and QA, helping shape both existing and new features from early concepts through to implementation.
We expect you to act as a proactive UX partner - identify friction, challenge existing solutions when needed, test assumptions, and help us establish stronger UX principles across both games.
While our studio is based in Prague, we offer the flexibility to work remotely within Europe (CET +/- 2 hours).
5+ years of professional experience as a UX Designer, Game UX Designer, or similar role, with significant experience working in the video game industry on PC and/or console games
~ Proven experience designing UX for shipped video games, ideally across multiple features or systems
~ Strong portfolio or case studies demonstrating your UX process, including problem definition, user
