[Hiring] Game Tools & Modding Engineer @Weekday AI

Role Description

We are looking for a Game Tools & Modding Engineer with strong expertise in graphics programming, rendering systems, and engine-level development to build high-performance, real-time applications. This role focuses on developing graphics systems, rendering pipelines, engine tools, and low-level optimizations using modern graphics APIs such as DirectX (DX11/DX12), Vulkan, OpenGL, or Metal.

If you have a strong background in game development, graphics programming, and engine architecture, and enjoy working close to the engine rather than gameplay logic, this opportunity is for you.

Key Responsibilities

• Engine & Tools Development
  • Design, develop, and maintain engine-level systems and game development tools using C++.
  • Build and enhance game modding tools, editor extensions, and development pipelines.
  • Extend engine capabilities to improve workflows for developers, artists, and designers.
• Graphics & Rendering
  • Develop and optimize rendering pipelines, shaders, and real-time graphics systems.
  • Implement graphics features using DirectX (DX11/DX12), Vulkan, OpenGL, Metal, or equivalent graphics APIs.
  • Work with HLSL/GLSL shaders and modern rendering techniques.
• Performance Optimization
  • Optimize rendering performance across CPU, GPU, memory, and multithreaded workloads.
  • Identify and resolve bottlenecks affecting graphics performance and engine efficiency.
  • Debug complex rendering, graphics, and cross-platform compatibility issues.
• Collaboration & Code Quality
  • Collaborate closely with engineers, technical artists, designers, and other stakeholders to deliver high-quality solutions.
  • Write clean, maintainable, and well-documented C++ code following engineering best practices.
  • Participate in code reviews, architecture discussions, and technical decision-making.

Qualifications

• 3–6 years of experience in game development, graphics programming, or real-time rendering.
• Strong proficiency in C++.
• Hands-on experience with one or more graphics APIs:
  • DirectX 11/12
  • Vulkan
  • OpenGL
  • Metal
• Solid understanding of:
  • Rendering pipelines
  • Shader programming (HLSL/GLSL)
  • 3D mathematics
  • Real-time graphics concepts
• Experience with Unreal Engine or a similar game engine.
• Knowledge of performance optimization techniques across CPU, GPU, memory, and multithreading.
• Strong debugging, analytical, and problem-solving skills.
• Ability to work independently in a distributed or remote team environment.

Preferred Qualifications

• Experience with engine customization and low-level systems programming.
• Familiarity with graphics profiling and debugging tools such as RenderDoc, PIX, Nsight, or similar.
• Experience developing cross-platform applications or working within performance-constrained environments.
• Exposure to game development tooling, editor extensions, asset pipelines, or automation.
• Background in multiplayer systems or large-scale game architectures.
