Job description

As a Senior Rendering Engineer, you will join world-class graphics engineers supporting the largest immersive 3D streaming environment deployed across console, desktop, mobile, and VR. Operating on an in-house rendering engine built from the ground up—supporting DirectX 9/11, OpenGL, GNM, Metal, and Vulkan—you will solve complex graphics challenges to push visual fidelity while guaranteeing cross-platform compatibility and minimal load times. In this role, you will innovate novel rendering techniques centered around caching, incremental computation, and graceful degradation to power dynamic, high-speed environments across high-end platforms and low-power devices alike.

Key Responsibilities

Real-Time Rendering & Engine Architecture

• Novel Rendering Innovations: Investigate, design, and implement cutting-edge rendering techniques to elevate visual expressiveness, real-time lighting, and atmospheric immersion across the Roblox platform.
• Cross-Platform Engine Optimization: Optimize rendering pipelines for multi-platform execution—ensuring backward compatibility for legacy assets alongside scalable graphics settings across desktop, mobile, console, and VR hardware.
• Low-Level GPU API Integration: Write and maintain low-level and high-level graphics code interfacing directly with GPU APIs (Vulkan, Metal, DirectX, OpenGL, GNM).
• Technical Artist Partnership: Collaborate closely with technical artists and creator tooling teams to understand current and future rendering requirements for creators of all experience levels.

Performance Engineering & Lifecycle Ownership

• Performance & Memory Tuning: Profile, reason about, and optimize engine execution paths to maximize frame rates and minimize memory consumption across diverse hardware configurations.
• Full-Lifecycle Project Ownership: Take complete technical ownership of graphics features from initial R&D and shader development through deployment, stability monitoring, and long-term support.

Requirements

Technical Depth & Graphics Foundations

• Experience Track: 6+ years of professional experience specializing in real-time rendering and 3D graphics development.
• C++ & Shading Mastery: Strong proficiency in modern C++ alongside hands‑on mastery of shading languages (HLSL, GLSL, MSL).
• 3D Math & Algorithmic Foundation: Deep expertise in 3D linear algebra, spatial math, rasterization/ray-tracing algorithms, and modern rendering techniques.
• GPU API Depth: Solid practical experience working with one or more GPU APIs (Vulkan, Metal, DirectX, OpenGL, GNM).
• Mobile/Console Development: Hands‑on experience delivering graphics features on mobile platforms (iOS/Android) or dedicated gaming consoles.
• Performance Reasoning: Demonstrated capability to profile, debug, and optimize low-level CPU/GPU performance and memory usage.
• Research Interest: Passion for staying updated on state-of-the-art computer graphics research, real-time techniques, and SIGGRAPH/GDC developments.

Preferred Qualifications

• Direct experience developing custom rendering features for proprietary, in-house 3D game engines.
• Familiarity with modern global illumination (GI), temporal anti-aliasing (TAA), compute shaders, or hardware-accelerated ray tracing pipelines.
• Track record of publishing or presenting original graphics rendering research.

Total Rewards & Benefits

• Compensation & Equity: San Mateo base salary range ($295,250 – $345,040 USD) + competitive Roblox equity compensation package.
• Healthcare & Wellbeing: Comprehensive health, dental, and vision insurance packages for employees and eligible dependents.
• Onsite Perks & Campus: Modern San Mateo headquarters featuring daily catered meals, team events, and state-of-the-art technical setups.
• Time Off & Retirement: Generous vacation policies, paid company holidays, paid parental leave, and 401(k) matching programs.
