Principal Rendering Engineer

Qualifications

• 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.

Our 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 to help you stay healthy and supported.
• Pension & life cover: A strong pension plan and life insurance to support your future and protect your family.
• Time for you: Minimum 25 days’ holiday, a paid winter break, and 3 volunteering days each year to give back to causes you care about.
• 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 to help you grow your skills and career.
