According to a job listing on the official careers page of Microsoft, it seems that company is looking to improve graphics performance of the Xbox One. The Advanced Technology Group within Microsoft are looking for a Software Engineer that has technical expertise in graphics performance optimization, GPU architectures, and HLSL shaders.
The job listing further states that the candidate should be able to make the GPU dance like it should be in a music video and improve frame hitches, possibly indicating towards frame rate optimization, and work directly with game developers to understand and address their technical problems and performance requirements. The Xbox One reportedly has a lesser GPU compared to the PlayStation 4, and optimization programmes such as these will go a long way in delivering better performing games on the console.
On a side note, Microsoft are also looking for Senior UX designer that will develop UI Frameworks and Wireframes for episodic storytelling features and blend Modern design language with the visual brand to create experiences. Since the listing states high quality video games, TV, or other entertainment products, we are not sure whether this is pointing towards a new game that will have strong story-telling or a new app that will be made available in the future on the Xbox One. Regardless, the idea of developing beautiful, usable, and delightful experiences for fans the world over sounds intriguing.
