Rendering / Engine Engineer

Job title: Rendering / Engine Engineer

About the Role Climax Studios is a co-development and full-development studio that partners with leading video game studios on custom engines. You will work deep in proprietary codebases on PC, current-gen consoles and Mac, writing low-level engine code against DirectX 12, Vulkan and Metal. This is frame-time engineering of the kind we delivered on Starfield and other technically demanding projects.

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

What We're Looking For

• 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

Nice to Have

• 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

Compensation & Benefits

• Flexible working: Remote-friendly long before it was the norm, with core hours that support both great work and real life
• Support & wellbeing: Mental health first-aiders, therapy and coaching via Myndup, plus private medical insurance
• Pension & life cover: A strong pension plan and life insurance
• Time for you: Minimum 25 days’ holiday, a paid winter break, and 3 volunteering days each year
• Parental leave: Family-first policies that support parents and caregivers with flexibility and balance
• Levelling up: Annual L&D budget, expert talks, game jams, and mentoring opportunities
