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.

Bermondsey Electronics is a contract electronics development company looking for an embedded software developer to expand the team. The successful applicant will work on a wide variety of systems, with different targets and design goals, based from the office in Bermondsey. We need a new engineer to be involved in peripheral and board bring-up. This means testing PCBs coming in from clients. Clients have occasionally tested boards but not always, and usually not fully. They might not have the skills or might not know how a specific peripheral works. Our job is to prove the board fundamentally works, and develop or debug drivers as necessary. Higher level application code is usually done by those specialists and is not expected to be a fundamental part of this role. It's a useful skill if you have it, though. In the last year, this has meant working with STM32, DA1453x, NXP iMX RT and RW6xx platforms, iMX 8M Plus and Nano. Software platforms range from bare metal to FreeRTOS to Zephyr, through Linux and all the way up to Android. At each stage, clients have either not been able to supply drivers, or a delivery from a supplier has had to be debugged or modified. With that done, the PCB is handed off to application developers, or the client will issue us another board to repeat the cycle. Suppliers usually deliver drivers in C. These are often of unknown quality. They may need configuration, and sometimes a device tree. As examples: We ported TI's CC3351 driver to STM32 and brought up lwIP on FreeRTOS We brought up a new iMX8MP Linux platform using LVDS and a bespoke RFID driver We rewrote an ESP32 bootloader for a client to update partition tables OTA We tested and verified RW610 power modes in Zephyr We rewrote the STM32 Eclipse ThreadX USB Audio Host driver to support USB MIDI We debugged an Infineon WiFi driver low power mode on Android on iMX8MP Typically LLMs do not have enough training data to help. They usually cannot work out schematic errors, or spot placement issues on a board. If you use LLMs heavily, you are unlikely to find them as useful in this role. It can mean writing and/or debugging drivers like SPI, DAC or LVDS. Typically test and measurement gear is needed, e.g. logic analyser, scope, bench power supply etc. There can be a lot of time configuring demo code to run in the mode the client requires, perhaps on a different target. When the code is running, we may need to capture signal traces to diagnose the fault. When we have the fault, we might need to change the code or the hardware, or both, for the client feature to work. Please note this role is not to develop hardware. Clients supply us boards to bring up. If you want to design PCBs from scratch, this is not the job for you. If you enjoy bringing up software stacks on new hardware, this is the job for you! Any knowledge of embedded OS is an advantage (FreeRTOS, Zephyr, Linux/Android, ThreadX). Ability with a soldering iron is useful. Familiarity with automated testing is useful but not required (e.g. hardware-in-the-loop). If you thrive in responsive, hands-on work and enjoy solving difficult problems efficiently, this could be the right role for you! Candidates must be eligible to work in the UK. No exceptions. We cannot sponsor a visa at this time. We cannot sponsor a candidate whose graduate visa will expire. Candidates must know embedded C programming and any one of the following: • Embedded Linux e.g. Yocto or Buildroot build system, • Python, • Android build system, • Networking and communication protocols, • Embedded OS use, • Power optimisation, • Makefiles / build configuration systems, • Basic soldering, • Unit testing 36 hours of full time effort are expected every week. Remote working is offered, although 2 days per week on site are required. Flexitime is offered as standard, although all hours must be accountable. 25 days' vacation are offered, growing with tenure. Job Types: Full-time, Permanent Pay: £55,000.00 per year Benefits: • Flexitime, • Sick pay, • Work from home Schedule: • 8 hour shift, • Flexitime, • Overtime Education: • Diploma of Higher Education (preferred) Experience: • C Programming: 1 year (preferred), • Software engineering: 1 year (required) Work authorisation: • United Kingdom (required) Work Location: Hybrid remote in London SE1 with 2 days per week on site near London Bridge.
