Job description

Redefining computing with seamlessly merging virtual, mixed and traditional reality takes us on a path of solving unique design and engineering challenges in areas such as rendering, interactions, 3D graphics engines and windowing.

You will be working as part of our core engineering team focused on building the Varjo XR software stack user interface. Your role will focus on working with interaction and input technologies as part of bringing our computing platform vision to life. Development tasks will range from architecting and developing how various iinput methods work with our XR solutions and building ways of visualising and using the interaction toolkit of the XR future. To be the right person for this role you should have experience of working with traditional 2D user interfaces supporting XR applications and have in addition a passion for building tools for people to use and create. 

Our developers, designers and HW engineers are world-class in what they do, and we want you to aim for the same level.

This is a full-time position located in Helsinki, Finland. Commuting from other cities in Finland is a possibility we can discuss and support. If you're currently based somewhere else, we will gladly help with relocating to the capital of the world's happiest country.


  • Developing user interfaces by co-working with other developers and designers for our core platform. 
  • Take accountability for solutions that are modular and testable. Have pride for building unit and regression testing to prove that your code and solutions truly work.
  • Debug, optimise and aspire to make things pixel perfect. Be willing to spend time in truly making things amazing, not just great.


  • Fluent with creating JS and C/C++ based desktop user interfaces with working history of over 7 years. Experience from TypeScript or VR application development can be seen as a bonus.
  • Track record of working on graphics-intensive and performance-critical projects in the 2D and/or 3D space. This can be gaming or any other similar background. 
  • Good grasp of modern large scale software development techniques in the areas of continuous integration, test driven development and the likes. 
  • Good communication skills in English.

We offer
