Senior Backend Engineer

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 (P ) accuracy - enabling the first real‑world P  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‑P  data‑set and training the next generation of AI models to assist artist workflows.

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 P  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 s 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 P  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 P  generation to artists world‑wide based on state‑of‑the‑art AI models that we create.

• Define, build and maintain the backend application services for our web SaaS platform, enabling new 3D‑P  asset creation workflows.
• Work with frontend developers to design and implement high‑performance APIs that deliver exceptional user experiences.
• Integrate with ML infrastructure to orchestrate model workflows, manage job queues, and deliver results to users.

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.
