• Diagnose and resolve rendering bugs, visual artifacts, and platform-specific rendering issues across target hardware.
• Build and maintain internal tooling to support artists and engineers working with rendering systems (profiling visualizers, lighting validation tools, etc.).
• Collaborate closely with technical artists on shader authoring standards, material complexity budgets, and visual fidelity guardrails.
• Contribute to and help enforce the studio's performance/fidelity standards documentation.
• Work within our Perforce/UGS/Horde pipeline, following team branching and Definition of Done standards.
• Stay current on Unreal Engine rendering roadmap changes (Lumen, Nanite, Substrate, etc.) and evaluate their fit for our production needs.
