Sjoerd “Hourences” de Jong, widely regarded by game developers as one of the most influential advocates and educators of Unreal Engine, has announced his departure from Epic Games. This marks the end of a remarkable era for the Dutch-born developer, who spent 27 years working with the iconic game engine and 12 years as a full-time employee at Epic Games. His departure represents a significant moment for the game development community, as de Jong has been instrumental in helping countless developers learn and master the Unreal Engine throughout his career.
De Jong’s journey with Unreal Engine began in the late 1990s when he started creating custom maps and modifications for games built on the platform. Over the years, he transformed from an enthusiastic hobbyist into one of the most respected voices in the Unreal development community. His dedication to sharing knowledge and creating educational content earned him the admiration of developers worldwide, establishing him as a bridge between Epic Games and the broader game development community.
A Legacy of Education and Community Building
Throughout his career, Sjoerd de Jong became synonymous with Unreal Engine education. He authored “The Hows and Whys of Level Design,” a comprehensive guide that became essential reading for aspiring environment artists and level designers. His tutorials, documentation contributions, and community engagement helped democratize access to professional game development knowledge. Before joining Epic Games officially, de Jong had already established himself as a go-to resource for developers struggling to understand the complexities of Unreal Engine.
During his 12-year tenure at Epic Games, de Jong contributed to numerous high-profile projects and initiatives. He worked on improving documentation, creating sample projects, and developing educational materials that made Unreal Engine more accessible to beginners while providing advanced insights for experienced developers. His role extended beyond traditional development work, as he frequently represented Epic at conferences, conducted workshops, and maintained active communication with the developer community through forums and social media.
The Evolution of Unreal Engine
De Jong’s 27-year involvement with Unreal Engine spans nearly the entire history of the technology. When he first started working with the engine in the late 1990s, Unreal Engine was primarily used for first-person shooters. Today, Unreal Engine 5 powers not only AAA video games but also film production, architectural visualization, automotive design, and virtual reality experiences. The engine has evolved from a specialized gaming tool into a versatile real-time 3D creation platform used across multiple industries.
Epic Games has transformed significantly during de Jong’s tenure. The company, founded by Tim Sweeney in 1991, grew from a modest game developer into a multi-billion dollar corporation. The success of Fortnite, launched in 2017, propelled Epic into the mainstream spotlight, while the company’s aggressive push to make Unreal Engine freely accessible to developers revolutionized the industry’s approach to game engine licensing. Throughout these changes, veterans like de Jong provided continuity and institutional knowledge that helped maintain the engine’s technical excellence.
Impact on the Game Development Industry
The departure of long-term veterans from major technology companies often signals broader industry shifts. De Jong leaves Epic Games at a time when the game development landscape is experiencing significant turbulence, with layoffs affecting studios worldwide and artificial intelligence beginning to reshape creative workflows. His accumulated knowledge and experience represent exactly the kind of institutional memory that companies risk losing during periods of transition and restructuring.
For the thousands of developers who learned Unreal Engine through de Jong’s tutorials and guidance, his legacy extends far beyond his official contributions to Epic Games. Many successful games and interactive experiences exist today because developers were able to access the knowledge he shared freely with the community. His influence can be traced through countless studios, projects, and careers that were shaped by his educational materials and mentorship.
Expert Opinion: The departure of foundational figures like Sjoerd de Jong from major engine developers often creates ripple effects throughout the industry, as their accumulated expertise and community relationships are difficult to replace. As Unreal Engine continues expanding into non-gaming sectors and competing with emerging technologies, Epic Games will need to cultivate new community champions who can maintain the educational ecosystem that made the engine so widely adopted. De Jong’s next venture will be closely watched by industry observers, as veterans of his caliber often go on to shape new tools, studios, or educational initiatives that influence the next generation of developers.
