LEGO Digital Play

LEGO Digital Play will bring the LEGO Brand into digital entertainment in new, innovative, and wholly-owned ways. Our mission is to ensure the LEGO Brand remains as powerfully a part of children’s lives in the coming decades as it has ever been. We aim to reach every kid on the planet, their parents, and adult fans of LEGO—and provide them with meaningful, magical, and playful new experiences.

Central Technology

Central Technology is the engineering heart of LEGO Digital Play, a venture within the LEGO ecosystem dedicated to pioneering creative and joyful digital experiences. Our teams build the foundational platforms, tools, and capabilities that power LEGO's Digital Future. We work at the intersection of play, applied AI, and developer tooling to bring the LEGO Brand to a new generation of digital builders. It's a rare opportunity to shape something from the ground up within one of the world's most loved brands.

We are at the earliest phases of this new company, offering a unique opportunity to build a new entity for the world's most beloved and trusted brand. Our culture is open, collaborative, intellectually rigorous, and creatively vibrant.

Role Summary

LEGO Digital Play is shaping the future of digital play by taking inspiration from the LEGO Brand’s System in Play and reimagining it for the digital world. Our portfolio is built on a foundation of safety that will ultimately inspire the builders of tomorrow.

We are looking for a Senior Engineer – Engine to help design and build our core runtime technology. This role is highly hands-on and focused on the implementation of critical engine systems, including simulation, performance optimization, rendering, runtime infrastructure across multiple environments, and the tooling that surrounds them.

Key Responsibilities

• Design and implement core engine systems, including runtime architecture, simulation systems, and performance-critical components, whether developing new systems or extending and integrating capabilities on top of existing game engines or engine technologies.
• Develop and optimize simulation and physics systems supporting large-scale interactive experiences.
• Build systems that support server-authoritative architectures, enabling efficient simulation across both client and backend environments.
• Implement and optimize rendering and graphical systems across multiple platforms.
• Contribute to the development of data-oriented engine systems, focusing on performance, scalability, and efficient memory usage.
• Design and implement streaming systems for runtime code, assets, and world data.
• Build and maintain the tooling that surrounds the engine — editors, inspectors, debuggers, profilers, build systems, and asset pipelines — treating internal engineering teams as first-class users and optimizing for their iteration speed.
• Work across low-level and high-level programming environments, building performance-critical systems in low-level languages while enabling higher-level scripting and tooling layers for other engineering teams.
• Collaborate closely with the broader platform engineering teams to ensure seamless integration between engine runtime and backend services.
• Contribute to building a high-velocity engineering environment that enables rapid iteration on a platform through strong engineering practices such as automated testing, automated performance validation, continuous integration, and robust development pipelines.
• Leverage and contribute to AI-powered development workflows, using AI-assisted coding, debugging, and prototyping techniques to accelerate development and improve engineering productivity.
• Prototype and experiment with new engine technologies to validate architectural and technical decisions.
• Contribute to a collaborative engineering culture where ideas are openly discussed and technical decisions are driven by shared ownership of the platform.
