Experienced Rendering Engineer

UK Remote or West Midlands Based - Birmingham/ Full-Time Contractor

Please Note: We welcome applicants that prefer to work from home, so please get in touch!

Role and Purpose: We are seeking an experienced rendering engineer to build, optimise, and maintain a multi platform rendering architecture targeting PC and console platforms. You will design cross platform rendering systems, develop platform specific backends, and ensure consistent performance and visual quality across a diverse hardware landscape.

Responsibilities:

• Develop and maintain rendering backends for: DirectX 11 and 12 on PC; Xbox Series X S (DirectX 12); PlayStation 5 GPU APIs
• Build scalable cross-platform graphics architecture including: GPU resource and memory management; Command list/queue abstraction and submission; Descriptor/binding systems and resource lifetime tracking; Shader compilation systems and pipeline state management
• Implement platform-specific optimisations leveraging: Async compute; Variable rate shading; GPU-driven pipelines (e.g., mesh shaders, indirect draws); Tile-based rendering considerations (Switch, some Android devices)
• Integrate rendering features across all platforms while maintaining predictable behaviour and performance
• Use platform GPU/CPU profiling tools to diagnose and resolve performance bottlenecks
• Collaborate with internal teams to ensure rendering systems support content workflows, shader pipelines, and engine features
• Produce high-quality, maintainable, and scalable rendering code
• Document complex rendering concepts and architectures in a manner for those less familiar to understand
• Assist as mentor to other engineers, contributing to team development through knowledge sharing and technical guidance

Requirements:

• Strong experience with modern PC and console graphics APIs such as: DirectX 12 (PC); Xbox GDK; PlayStation 5 low-level GPU APIs
• Deep understanding of GPU architecture, memory models, and rendering pipeline internals across multiple hardware classes (desktop and console)
• Proficiency in C++ with a focus on performance-critical systems
• Experience implementing or maintaining multiplatform rendering layers
• Strong understanding of: GPU synchronization and resource state transitions; Descriptor and binding models; Multithreaded rendering pipelines; Shader languages (HLSL essential; GLSL and platform shader variants a plus)
• Experience using GPU debugging and profiling tools (PIX, Razor, Nsight, RenderDoc, Android GPU profilers)
• Experience working with or implementing shader compilation pipelines, including: Integrating platform specific shader compilers (e.g. DXC, FXC); Generating reflection metadata; Managing shader permutations and build workflows
• Experience with GPU task scheduling, async compute, parallel command list building, and multi-queue/submission models for modern graphics APIs
• Streaming and virtualized textures: Sampler feedback streaming and architecting virtual texturing systems, including: Page tables mapping virtual to physical memory; Fallback MIPS; Load/evict streaming based on visibility
• Experience with other modern graphics APIs: Vulkan; OpenGL ES (Android); Switch and Switch 2 low-level GPU APIs; Switch 2 DLSS implementation; Metal (Apple)
• Familiarity with tiled/clustered lighting techniques and mobile-optimised rendering
• Multiplatform game development experience across console/PC and mobile
• HDR pipeline experience: HDR10, Dolby Vision implementation
• Integration and usage of upscalers such as e.g. FSR, DLSS, XeSS, PSSR (PS5 Pro)
• Raytracing experience with DX12 and PS5

Please include your CV, portfolio, and cover letter (optional) within your application. If your examples are from previous works with another studio, please ensure samples are cleared for release by copyright owners. Links to an online portfolio are preferable; otherwise showreels via Dropbox or other secure sharing platforms are accepted.
