Job description

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 multi‑platform 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. This includes: – 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.
• Multi‑platform game development experience across console/PCand mobile.
• HDR pipeline experience: HDR10, Dolby Vision implementation
• Integration and usage of upscalers such 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.
