Core Responsibilities

Primary Functions

Support senior graphics engineers by implementing and iterating on real-time shaders (HLSL/GLSL/Metal) and shader variants, ensuring consistent visual fidelity across platforms while adhering to memory and performance budgets.
Assist in integrating new rendering features into the engine pipeline (Unreal Engine, Unity, or proprietary engines), including feature toggles, shader permutations, and build-time shader compilation pipelines.
Profile and analyze CPU and GPU bottlenecks using industry tools (RenderDoc, PIX, NVIDIA Nsight, Xcode GPU Frame Capture), generate clear performance reports, and propose prioritized optimization plans for frame-time reduction.
Collaborate with artists and art directors to translate look-development prototypes into production-ready shader code, maintaining artist-friendly parameters and documentation for shader graphs and material systems.
Implement and optimize real-time lighting models, including physically based rendering (PBR), BRDFs, image-based lighting, global illumination approximations, and shadowing techniques to achieve target visual quality.
Develop and maintain post-processing effects (tone mapping, bloom, motion blur, depth of field, color grading) and ensure efficient integration into the frame graph or render pass system with proper dependency tracking.
Assist in building and testing GPU-driven rendering techniques such as GPU culling, indirect draw calls, compute-driven LOD selection, and GPU particle simulation to scale large scenes and crowds.
Maintain and evolve the engine's rendering architecture, contributing to render graph, multi-threaded command submission, synchronization primitives, and resource lifecycle management for cross-platform support.
Contribute to cross-platform graphics API implementations: write and maintain backend code for Vulkan, DirectX 12, Metal, and fallback OpenGL paths; adapt shaders and resource bindings for each target.
Troubleshoot and fix graphical artifacts, precision issues, and platform-specific rendering bugs by reproducing, isolating, and applying robust fixes while documenting root causes and mitigations.
Implement support for modern features such as hardware-accelerated ray tracing (DXR/RTX, Vulkan ray tracing), denoising pipelines, and hybrid rasterization-ray tracing integrations under the guidance of senior engineers.
Optimize GPU memory usage and streaming of textures, meshes, and shader data by implementing efficient packing, compression, and residency strategies to meet console and mobile constraints.
Write and maintain shader preprocessing, permutation management, and automated shader compilation systems to minimize load times and reduce runtime shader stutters.
Participate in code reviews, enforce consistent coding standards for C++ and shader code, and mentor junior team members on best practices for safe, maintainable graphics code.
Implement unit tests, integration tests, and visual regression tests for rendering subsystems; create automated test baselines and CI checks to prevent regressions in frame rendering.
Assist with platform-specific performance tuning and compliance for consoles and mobile platforms, including GPU profiling, CPU affinity, threading models, and API-specific optimizations.
Work with tools and pipeline teams to create or improve editor tools for material editing, shader debugging, and visualization aids (G-buffers, overdraw, memory heatmaps) that accelerate iteration for artists and devs.
Support asset pipeline improvements: advise on optimal mesh formats, vertex layouts, skinning/animation data, and texture formats to reduce vertex fetch, cache misses, and bandwidth pressure.
Participate in sprint planning, grooming, and estimation; break down feature work into actionable tasks, produce accurate engineering estimates, and communicate progress to stakeholders.
Research and prototype emerging rendering techniques (e.g., screen-space global illumination, clustered/ tiled/forward+ lighting, temporal accumulation strategies) and produce POCs to inform roadmap decisions.
Collaborate with QA to reproduce GPU/driver regressions, prepare test cases, and implement automated reproduction scripts or sample projects to isolate issues for vendor debug.
Maintain and curate technical documentation, shader comments, and knowledge base articles to onboard new team members and preserve institutional knowledge of rendering systems.
Help implement localization-safe, thread-safe logging and telemetry for rendering performance metrics to drive data-driven optimization efforts in production builds.

Secondary Functions

Support ad-hoc data requests and exploratory data analysis for rendering telemetry and performance metrics.
Contribute to the organization's graphics strategy and long-term roadmap by feeding back learnings from profiling, POCs, and external research.
Collaborate with business units (art, design, QA, tools) to translate visual and technical requirements into engineering tasks and deliverables.
Participate in sprint planning and agile ceremonies within the graphics and engine teams and help refine backlog items into development-ready tasks.
Provide occasional on-call support during critical platform certification windows, responding to graphics regressions or performance problems under time constraints.
