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. In your role you will be accountable for bridging the capabilities of our HMD and tooling with the Unreal Engine and working on the pipeline, architecture, tools and visual perfection we deliver with our immersive computing platform. As part of the work, you are bound to go deep into the source code and behaviour of the Unreal Engine itself and make relevant changes to make it suitable for our needs. To be the right person for this role, you must have expertise in working with the internals and source code of Unreal Engine (or another 3D game engine) and a passion for crafting the fundamentals for graphics-intensive experiences.

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.
