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. 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. You will: • Define, build and maintain the backend application services for our web SaaS platform, enabling new 3D-PBR 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. What you will do • Design and implement user-facing APIs to support frontend user flows (FastAPI), • Build robust user authentication, authorisation, and account management (Auth0), • Integrate payment processing and subscription management (Stripe), • Design and manage user databases and data models (MongoDB, PostgreSQL), • Implement asset storage, retrieval, and management systems (AWS S3), • Build job queue management for async ML workflows (SNS, SQS), • Setup application monitoring and logging (CloudWatch, Grafana, Prometheus), • Implement CI/CD for application deployment (Bitbucket Pipelines), • Create API documentation and developer tools What we are looking for • 5+ years backend development experience with production applications, • Track record with at least one live application currently serving users in production, • Proven experience designing and implementing RESTful APIs at scale, • Strong experience with Python and modern web frameworks, • Comfortable working in TypeScript for frontend integration debugging, • Experience in building infrastructure for image / video / 3D or graphics-intensive / data-intensive web apps Bonus points • Experience working with researchers, product engineering and product managers bringing new AI capabilities to market, • A love of games, films and understanding of photogrammetry, scanning, graphis, rendering and AAA 3D asset creation.

What You’ll Be Doing • Own the technical success of enterprise deployments across thousands of PoS + edge devices, • Troubleshoot end-to-end: AI model behaviour, device integrations, networks, cloud infra, on-device performance, • Analyse logs, metrics and telemetry (Grafana, Metabase) to pinpoint root cause, • Work hands-on with Linux, SQL, Docker, AWS/GCP/Azure, • Lead pilots, rollouts and on-device testing across major retail estates, • Collaborate with Engineering, ML, and Product to improve reliability + performance, • Manage incidents from first alert to identifying product-level bugs, • Translate complex technical issues into clear, actionable guidance for enterprise retail clients, • Act as the dedicated technical point of contact for strategic accounts Ideal Background You’re a hands-on, client facing, technical support engineer with real ownership experience in live customer environments, ideally within RetailTech (SaaS), PoS systems, edge AI, computer vision, or IoT. You understand: • Edge ML pipelines (training, validation, orchestration), • Retail IT infrastructure (PoS, SCO, store networks), • Integration frameworks (APIs, SDKs, cloud-edge sync) Technical Requirements Strong troubleshooting across: • SQL, • Linux / OS-level commands, • Docker / containers, • Cloud (AWS, GCP, Azure), • Log analysis, performance monitoring, • Diagnosing issues across AI models, integrations, networks, device hardware, cloud layers Highly relevant backgrounds: • Technical Support Engineer (L2/L3), • Solutions Engineer, • Platform Support Engineer / SRE-lite, • Deeply technical TAM (SaaS/AI/IoT), • Experience with distributed systems, edge devices, IoT or ML/AI environments Why Join • Work across AI, PoS vision, hardware, cloud, edge, distributed systems, • Massive technical variety, no two issues look the same, • Direct input into product decisions, • Equity with meaningful upside, • Real-world impact across thousands of retail devices globally, • Perfect for engineers who want customer-facing work without sacrificing technical depth Interested? If you’re a strong technical trouble shooter who thrives on autonomy, complex systems, and customer-facing support engineering in the world of RetailTech and PoS AI, we’d love to speak with you.

About Us: We’re a VC-backed stealth-mode company building behavioural AI solutions for the retail industry. Our platform is designed from the ground up — no legacy, no patchwork systems — just a clean slate and a clear vision. Our mission is to bring the intelligence of modern machine learning directly to the in-store shopping experience. Role: We’re looking for an experienced Full Stack Engineer to work closely with product, design, mobile, and machine learning team members to design & build experiences that re-define in-store shopping. You'll help help build engaging & intuitive web experiences and the event-driven & real-time backend services that power them. You’ll work across the stack, implementing highly responsive UI components and real-time data flows and APIs on a backend designed for scale & flexibility. Responsibilities: • Design and implement reactive, real-time web interfaces that help manage & redefine what is possible with in-store content personalisation, • Contribute to distributed, event-driven backend services connecting our web experience with information from remote devices and external data sources., • Build and document APIs (OpenAPI/AsyncAPI) for mobile and web clients, • Model and manage structured and semi-structured data across storage layers, • Integrate AI-driven personalisation and real-time insights into user flows, • Contribute to overall system design: service boundaries, data ownership, scaling, and observability Essential Qualifications: • Built modern full-stack applications (Python/Java/Go + React), • Worked with a variety of storage technologies (eg. Postgres, Mongo, Redis, Object), • Experience with async and bi-directional communication protocols and patterns (eg. WebSockets, SSE), • Designed and implemented event-driven distributed systems (eg. Kafka/Pulsar, RabbitMQ, MQTT, or similar), • Experience with container orchestration and service containerisation (Kubernetes, Docker), • Built and deployed services on any major cloud providers' services (Azure, GCP, AWS), • Worked with AI development tools (eg. Bolt, Lovable, Cursor) to speed up iteration & prototyping Nice to Have: • Worked with real-time data collection and/or processing, • Worked in an IoT or Edge-oriented architectures, • Experience or knowledge in retail POS, inventory, or loyalty systems
