Job Description

As a Technical Director for the Engine Data Model at Roblox, you will define the technical vision and lead the evolution of one of the most fundamental components of the Roblox Engine: the Data Model. The Data Model serves as the core representation of all objects in a 3D Roblox experience—from terrain, lighting, and parts to the scripts that drive dynamic, interactive behavior. It is the connective tissue that powers the structure and runtime behavior of every Roblox world.

In this role, you will lead the most ambitious engineering initiatives aimed at scaling the Data Model to support Roblox’s growing complexity and future aspirations. Your work will directly shape the performance, scalability, and extensibility of the engine that underpins millions of daily user experiences.

We are looking for a visionary technical leader with deep experience in systems programming and platform design, who is excited to take on challenging problems at the core of a real-time engine. This is a rare opportunity to build and evolve one of the key technologies that make Roblox special!

You Will:

• Define and lead the technical roadmap for the Roblox Engine Data Model, with a focus on scalability, performance, and extensibility.
• Design and build core engine systems that support the dynamic, interactive 3D environments Roblox is known for.
• Lead by example as a hands-on individual contributor while setting architectural and engineering standards.
• Author and review design documents and technical specifications for foundational platform features.
• Partner closely with engineering, product, and design teams to deliver seamless, intuitive collaboration experiences.
• Become an expert in Roblox's proprietary technology stack and ensure that all development aligns with long-term goals and best practices.
• Explore and evaluate emerging technologies, balancing innovation with execution.
• Represent Roblox in relevant industry forums and communities, acting as a technical ambassador for our platform.
