Climax Studios
Principal Rendering Engineer - MPG - Fully remote from the UK or the EU
MPG is a co-development and full-development studio that partners with the leading video game studios on their custom engines: new rendering features, high performance and graphics systems that scale across AAA games, real-time simulation and XR. You'll work deep in proprietary codebases on PC, current-gen consoles and Mac, writing low-level engine code against DirectX 12, Vulkan and Metal. No editor scripting, no glue work. This is frame-time engineering of the kind we delivered on Starfield and other technically demanding projects.
Requirements
● An established track record in rendering or engine engineering, shipping high-performance rendering systems for AAA, film/VFX, XR or simulation across a number of products
● Deep experience with modern C++ and solid shader authoring and debugging (HLSL, MSL or GLSL)
● Production experience shipping with at least two of Metal, DirectX 12, Vulkan or GNM/GNMX
● Deep working knowledge of the full pipeline: rasterization, compute and hardware-accelerated ray tracing
● Fluency in modern rendering techniques: PBR, GI, ambient occlusion, volumetrics, and post-processing (AA, HDR, tone mapping, motion blur), with awareness of current GPU-driven pipelines, meshlet rendering, and real-time path tracing workflows
● Comfortable dropping into unfamiliar codebases and making sound architectural calls independently
● Solid applied 3D maths, plus technical writing other engineers actually want to read
Bonus Points
● Practical experience with mesh shading pipelines (DX12, Vulkan, Metal) to optimize geometry processing and reduce CPU overhead
● Familiarity with modern hardware variations, including console and Apple Silicon unified memory architectures
● Shipped ray tracing or heavily compute-driven rendering
● Extensive Unreal Engine source modifications
What You'll Do
● Turn the art team’s vision into shippable, scalable rendering technology
● Design, build and maintain high-performance rendering backends with clean abstractions across PC, console and Mac
● Profile and resolve deep GPU/CPU bottlenecks: occupancy, tile memory pressure, indirect dispatch overhead, bandwidth ● Modernize pipelines with GPU-driven culling, indirect command buffers and bindless architectures
● Design concurrent GPU memory management on modern API features and memory heaps
● Extend major engines (including Unreal source) and custom C++ architectures
● The opportunity to represent the studio externally through white papers or presenting at industry events
