Core Responsibilities

Primary Functions

Design, implement, and maintain robust, scalable, and high-performance real-time visual effects systems, including particle systems, fluid dynamics, and procedural generation.
Develop and optimize complex shaders using HLSL, GLSL, or node-based editors to achieve unique and high-quality visual effects for characters, environments, and UI.
Architect and build custom tools, plugins, and pipeline improvements within game engines (like Unreal or Unity) to enhance the workflow and capabilities of the VFX art team.
Profile and optimize the performance of visual effects on both CPU and GPU to ensure projects meet strict frame-rate targets and memory budgets across all target platforms (PC, console, mobile).
Collaborate closely with Art Directors, VFX Artists, and Designers to understand the creative vision and translate artistic requirements into technical solutions and achievable features.
Write clean, maintainable, and well-documented C++ code within a large, multi-disciplinary codebase, ensuring stability and extensibility of the graphics and VFX engine components.
Research and develop innovative rendering techniques and algorithms, staying ahead of industry trends and academic publications (like SIGGRAPH) to drive the next generation of visual fidelity.
Debug and resolve complex, time-sensitive graphical issues, from shader compiler errors to low-level rendering artifacts, often requiring the use of tools like RenderDoc or PIX.
Integrate and manage third-party libraries and technologies related to physics, simulation, and rendering to expand the engine's VFX capabilities.
Develop and support data-driven systems that empower artists to iterate quickly and control the look and behavior of effects with minimal engineering intervention.
Implement and refine post-processing effects such as bloom, depth of field, and color grading to enhance the overall mood and final visual quality of the scene.
Author comprehensive technical documentation for new systems, features, and tools to serve as a resource for both the engineering and art teams.
Create and maintain a library of master materials and shaders that serve as a foundation for the art team, ensuring consistency and performance across all effects.
Implement procedural systems for large-scale environmental effects, such as dynamic weather, volumetric clouds, and interactive water systems.
Work with the animation and character teams to create systems for dynamic effects that are attached to characters, such as magic spells, weapon trails, and impact effects.

Secondary Functions

Mentor and guide junior engineers and technical artists, providing constructive code reviews and sharing knowledge to foster team growth.
Contribute to the long-term technical roadmap and strategy for the studio's graphics and visual effects technology stack.
Participate in the hiring process for technical roles, including reviewing portfolios, conducting technical interviews, and evaluating candidates.
Create and present technical presentations and demonstrations of new VFX technologies to internal teams and stakeholders.
Investigate and prototype emerging hardware and software technologies to assess their potential for future projects.
