Unity 3D Rendering Engineer Jobs (NOW HIRING)

The Roblox Vision

Every day, tens of millions of people come to Roblox to explore, create, play, learn, and connect with friends in 3D immersive digital experiences - all created by our global community of developers and creators. At Roblox, we're building the platform that empowers our community to bring any experience imaginable to life. Our vision is to reimagine the way people come together, from anywhere in the world, and on any device. We're on a mission to connect a billion people with optimism and civility.

Why Join Our Rendering Team?

Roblox is seeking an experienced and passionate senior engineering manager to lead a team of talented engineers building cutting edge rendering technology.

The rendering team at Roblox is at the heart of how millions of creators and players experience our platform. We are a group that is highly passionate about pushing the boundaries of visuals, scalability and performance. We develop our in-house engine and are in control of our entire technology stack, from the rendering pipeline, the lighting techniques, the material system, the voxel terrain to the VFX system and the server infrastructure. 

Roblox continues to tackle an unprecedented scalability challenge: to allow User Generated Content to take advantage of high end devices while scaling all the way down to low end mobile devices, across a vast array of platforms and genres. Our technology stack and features must allow Creators to express their amazing vision and we must cater to Creators that range from professional developers to enthusiastic newcomers. Our engine must be capable of producing visuals that  look great on high end devices while preserving their intent on low end devices.

The Roblox platform has an immense reach. Our work makes it into the hands of hundreds of millions of users all over the world.

You will:

• Lead and mentor a world-class team of rendering engineers focused on one of the following pillars:
• The core rendering pipeline, culling and dispatching systems, graphics APIs backends (Vulkan, Metal, Direct3D, agc, OpenGL) and related systems.
• The Lighting, shading, materials, global illumination, and post-processing systems.
• Act as a hands-on technical leader, providing guidance on architectural decisions and implementation, from low-level details to high level choice of algorithms, and ensuring the stability and efficiency of our technology stack.
• Partner with your team and other engineering leaders to define and execute the vision for the core rendering technology, anticipating future needs and trends, and ensuring our plans are aligned with the company vision.
• Foster a culture of innovation, continuous improvement, and open communication, where all ideas are valued and explored, and invest in the development of our engineers.
• Help build and expand our rendering organization by attracting, interviewing, and retaining top-tier engineering talent.

You have:

• 15+ years of rendering or graphics engineering experience, with a deep understanding of one or both of the following:
• Low-level rendering pipelines, GPU architectures (preferably including mobile), and graphic APIs (e.g., Vulkan, Metal, DirectX)
• Modern lighting techniques (e.g., PBR, shadowing, global illumination), material systems, and shading languages.
• 5+ years of experience in a technical leadership or engineering management role, with a proven track record of building, mentoring, and leading high-performing engineering teams.
• Strong C++ programming skills and a robust problem-solving background, with the ability to provide technical guidance, conduct deep-dive investigations, and contribute to design discussions.
• Experience designing, building, and shipping advanced graphical features and/or performance critical systems for game engines or real-time 3D applications.
• Strong communication and interpersonal skills, with the ability to articulate complex technical concepts clearly to both technical and non-technical audiences and collaborate effectively across diverse teams.
• A genuine enthusiasm for tackling the unique rendering challenges that Roblox faces.
