Senior C++ Software Engineer - AI

Senior C++ Software Engineer – XR, Real-Time 3D & High-Performance Streaming (m/f/d)Germany | Full-time | PermanentBuild the technology redefining how humans interact with the digital worldJoin one of Europe’s most exciting venture-backed deep-tech companies and help build the infrastructure powering the next generation of Augmented Reality, Virtual Reality and spatial computing.This is not another maintenance-heavy C++ position.You will work at the intersection of modern C++, XR, real-time 3D, GPU rendering, cloud streaming and AI-enabled industrial technology. The platform enables global organisations to stream complex, high-fidelity 3D applications securely across devices—transforming how engineers design products, operate factories, deliver training and collaborate with immersive data.The business is already established internationally, works with leading global enterprises and is now entering its next major stage of growth. You will join a talented engineering team with genuine influence over the architecture, technical direction and future of a category-defining product.The CompanyOur client is a fast-growing, venture-backed enterprise technology company specialising in XR infrastructure, immersive software and high-performance application streaming.Its proprietary technology allows organisations to securely stream and manage demanding AR and VR applications across different devices and locations. This removes hardware limitations and enables engineers, designers and operational teams to interact with complex 3D data in real time.Founded in Europe and now operating internationally, the company supports customers across sectors including manufacturing, engineering, automotive, aerospace and industrial technology.This is an opportunity to join a business building foundational technology for a future where XR, AI, cloud computing and real-time 3D converge.If you want your C++ expertise to power technology that feels genuinely futuristic—and is already solving real industrial problems—this is the opportunityYour MissionAs a Senior C++ Software Engineer, you will help evolve a sophisticated XR streaming SDK built for performance, scale and compatibility across devices and platforms.You will:Architect and develop new capabilities within a high-performance C++ SDKBuild and extend integrations based on OpenXRCreate seamless compatibility with leading XR headsets and rendering platformsExpand a modern plugin ecosystem for Unreal Engine, Godot and other real-time 3D enginesWork deeply with GPU rendering pipelines using Vulkan and/or Direct3D 12Optimise latency, frame rates, rendering performance and streaming qualityImprove software architecture, modularity, testability and long-term scalabilityContribute to cross-platform development across Windows, Android and iOSEvaluate emerging technologies across XR, spatial computing, AI-assisted workflows and cloud renderingHelp solve complex technical problems where graphics, networking, devices and real-time software meetInfluence engineering standards, technical decisions and the future product roadmapThe Technology LandscapeYou will have the opportunity to work with technologies including:Modern C/C++ | OpenXR | Vulkan | D3D12 | Unreal Engine | Godot | WebRTC | Real-Time 3D | GPU Rendering | Video Streaming | Windows | Android | iOS | Cloud XR | Spatial ComputingThis is an engineering environment where performance matters. Milliseconds matter. Architecture matters. Your work will directly determine how smoothly complex industrial XR experiences can be streamed and used around the world.What You BringAt least five years of professional C/C++ software-engineering experienceStrong knowledge of modern software architecture, object-oriented design and clean-code principlesExperience building substantial, production-grade software productsA good understanding of 3D rendering pipelines using Vulkan and/or D3D12Confidence working with complex systems where performance, stability and scalability are criticalA degree in Computer Science, Software Engineering or a comparable disciplineFluent English communication skillsCuriosity, technical ambition and the desire to build something genuinely innovativeExperience in one or more of the following would be highly beneficial:Developing against the OpenXR specification in C/C++Unreal Engine, Godot or another real-time 3D engineCross-platform software developmentWebRTC or low-latency video-streaming technologyAR, VR, XR or spatial-computing productsGPU optimisation and graphics programmingCloud rendering or distributed real-time systemsAI-enabled visualisation, simulation or industrial applicationsYou do not need to match every point. If you are an excellent C++ engineer with a passion for graphics, performance and modern technology, we still want to hear from you.Why Join?Build a product at the frontier of XR, spatial computing and industrial AIJoin a well-funded, venture-backed European technology scale-upWork on deep technical challenges—not repetitive maintenance developmentShape a platform used for real-world engineering, manufacturing and trainingInfluence architecture and product direction from an early stageWork alongside an international team of highly skilled engineersEnjoy significant technical ownership and creative freedomDevelop your career as the engineering organisation continues to scaleBenefit from a modern working environment and flexible home-office optionsReceive additional benefits including private health insurance, public-transport support and a gym subsidyJoin a culture built around curiosity, collaboration, high standards and genuine recognitionThe CompanyOur client is a fast-growing, venture-backed enterprise technology company specialising in XR infrastructure, immersive software and high-performance application streaming.Its proprietary technology allows organisations to securely stream and manage demanding AR and VR applications across different devices and locations.
