Why Join Us

A unique opportunity to join in on the ground floor at one of the most exciting games startups in the UGC space. This studio is building the ultimate open-world multiplayer sandbox. We’re an international team, who raised $11M in capital from top gaming VCs, currently in pre-alpha. Our mission: a moddable platform that empowers creators and excites players, where the creativity of GTA role-play and Roblox, meets next-gen quality delivered by Unreal Engine 5.

About the Role

We’re seeking a Senior Graphics Programmer with strong Unreal Engine 5 experience to help shape the look and performance of a next-generation open-world multiplayer game. You’ll take ownership of rendering systems at both the engine and project level, pushing the boundaries of visual fidelity, procedural world rendering, and runtime performance. Working closely with world, tools, and art teams, you’ll ensure large-scale environments are both beautiful and efficient, leveraging UE5’s procedural content generation (PCG) tools and related systems to dynamically create and render vast worlds at high frame rates.

This is an opportunity to work with a highly skilled engineering and art team on an ambitious title that blends large open environments, multiplayer gameplay, and cutting-edge technology.

Key Responsibilities

Develop and extend Unreal Engine 5’s rendering systems using C++ and RDG (Render Graph).

Optimize Nanite, Lumen, Virtual Shadow Maps, and Virtual Texturing for large open worlds.

Integrate and extend Unreal PCG (Procedural Content Generation) tools for efficient, dynamic environment generation.

Implement rendering-friendly procedural workflows that maintain high visual fidelity and scalability.

Profile and optimize rendering performance across PC and console platforms using RenderDoc, Unreal Insights, PIX, and Nsight.

Collaborate with technical artists and environment teams to balance art direction with performance.

Tune and maintain HLOD, streaming, and culling systems for world partitioned environments.

Implement scalable lighting, atmospheric, and volumetric rendering solutions.

Optimize for cross-platform rendering (DirectX 12, Vulkan, PS5, Xbox Series X|S).

Support real-time global illumination, ray tracing, and temporal rendering techniques (TAA/TSR).

Ensure rendering systems integrate cleanly with multiplayer replication and networked gameplay.

Contribute to tooling, debugging, and performance regression automation for rendering features.

Required Skills & Experience

5+ years professional experience in rendering or graphics programming.

2+ shipped titles, including at least one open-world or AAA project.

Deep expertise in Unreal Engine 5 rendering architecture — Render Graph (RDG), Nanite, Lumen, VSM, and Virtual Texturing.

Strong C++ and HLSL skills; comfortable working in Unreal’s engine source.

Solid understanding of procedural generation systems, ideally Unreal PCG (or comparable systems such as Houdini Engine, World Machine, or in-house procedural frameworks).

Experience building or optimizing rendering pipelines for large-scale open worlds.

Proven record in GPU/CPU performance optimization and multi-threaded rendering.

Hands-on experience with profiling tools — Unreal Insights, RenderDoc, PIX, Nsight, Intel GPA.

Strong grasp of lighting, post-processing, and temporal techniques (TAA, TSR).

Experience with asynchronous compute, shader optimization, and memory management.

Excellent cross-discipline collaboration skills (art, design, tools, and network teams).

Desirable Skills

Experience integrating procedural generation tools (e.g., Houdini, Gaia, Gaea, or custom node-based systems).

Understanding of world streaming, terrain tessellation, and massive world optimization.

Knowledge of ray tracing, hybrid rendering, and temporal reconstruction techniques.

Familiarity with multiplayer rendering synchronization and networked visual effects.

Experience developing rendering plugins or contributing to engine-level features.

Strong interest in pushing real-time rendering innovation and next-gen visual fidelity.

Based in or able to relocate/commute to Guildford or London, UK (hybrid or on-site preferred).
