Our vision From blockbuster films and AAA games to immersive experiences, the demand for photo-real 3D content has never been higher - but creating photorealistic assets is slow, expensive, and manual with no current scalable solution available. At M-XR, our mission is to democratise the creation of high-quality 3D assets and empower brands, studios, and creators to build infinite photo-real 3D experiences. Our proprietary technology Marso allows anyone to capture real-world objects into production-ready photorealistic digital twins with unmatched material (PBR) accuracy - enabling the first real-world PBR capture pipeline that can operate anywhere. Marso is trusted by the most demanding studios in film and gaming. We see the future of 3D as AI-assisted, and we’re building the tech to make that happen. We are creating the world’s highest quality and most comprehensive 3D-PBR data-set and training the next generation of AI models to assist artist workflows. See the result yourself — passcode: scaneverything About the role ✨ We are looking for a Senior Backend Engineer to join the team and be the driving force that designs, builds and scales the backend application services for our web platform. At M-XR we developed Marso as a way to capture real-world PBR material data alongside conventional photogrammetry from simple flash photography. Marso is now actively being used by an array of studios, brands & museums to digitise previously unobtainable assets at scale. This gives us one of the most unique and physically accurate 3D datasets in the world. Now we’re building an ML-powered pipeline that can automatically predict material properties (diffuse, roughness, specular, metallic, normals) from photogrammetry input alone - without flash. This is made possible by tapping into our uniquely rich dataset of real-world material scans. Our goal is to remove the need for manual texturing and enable full end-to-end automation, from photos to PBR assets at high fidelity and scale. You’ll be helping bring this technology to market. We are creating a web SaaS platform that will bring completely new capabilities for PBR generation to artists world-wide based on state-of-the-art AI models that we create. Where you will have impact! 🚀 As the Senior Backend Engineer for our web platform, you’ll be responsible for bringing a completely new product to market based on state-of-the-art AI capabilities.

This is a high-impact role for someone that loves to define and bring completely new technologies to market - with the experience that defines how we do it.
