Principal Rendering Engineer

This is a fully remote position, open to applicants in United Kingdom.

📋 Description

• Transform the vision of the art team into deployable and scalable rendering technology.

• Create, develop, and sustain high-performance rendering backends with clear abstractions across PC, console, and Mac platforms.

• Analyze and mitigate significant GPU/CPU bottlenecks, including occupancy, tile memory pressure, indirect dispatch overhead, and bandwidth issues.

• Update pipelines with GPU-driven culling, indirect command buffers, and bindless architectures.

• Design concurrent GPU memory management leveraging modern API features and memory heaps.

• Extend major engines (including Unreal source) and custom C++ architectures.

• Represent the studio externally through white papers or by presenting at industry events.

⛳️ Requirements

• Proven experience in rendering or engine engineering, successfully shipping high-performance rendering systems for AAA, film/VFX, XR, or simulation across various products.

• Extensive knowledge of modern C++ and proficient in shader authoring and debugging (HLSL, MSL, or GLSL).

• Practical experience in shipping with at least two of the following: Metal, DirectX 12, Vulkan, or GNM/GNMX.

• Comprehensive understanding of the entire pipeline: rasterization, compute, and hardware-accelerated ray tracing.

• Proficiency in contemporary rendering techniques: PBR, GI, ambient occlusion, volumetrics, and post-processing (AA, HDR, tone mapping, motion blur), along with awareness of current GPU-driven pipelines, meshlet rendering, and real-time path tracing workflows.

• Ability to navigate unfamiliar codebases and make sound architectural decisions independently.

• Strong applied 3D mathematics skills, along with technical writing that engages other engineers.

• Bonus Points

• Hands-on experience with mesh shading pipelines (DX12, Vulkan, Metal) to enhance geometry processing and minimize CPU overhead.

• Familiarity with modern hardware variations, including console and Apple Silicon unified memory architectures.

• Experience in shipping ray tracing or heavily compute-driven rendering projects.

• Extensive modifications to Unreal Engine source.

🏝️ Benefits

• Flexible working arrangements: Remote-friendly long before it became standard, with core hours that accommodate both excellent work and personal life.

• Support & wellbeing: Access to mental health first-aiders, therapy, and coaching through Myndup, as well as private medical insurance to ensure you remain healthy and supported.

• Pension & life cover: A robust pension plan and life insurance to secure your future and safeguard your family.

• Time for you: A minimum of 25 days’ holiday, a paid winter break, and 3 volunteering days each year to contribute to causes you are passionate about.

• Parental leave: Family-oriented policies that provide support for parents and caregivers with flexibility and balance.

• Levelling up: An annual learning and development budget, expert talks, game jams, and mentoring opportunities to help you enhance your skills and advance your career.
