About the Role & Team

Disney Digital Entertainment, a division of Disney Entertainment, is redefining how audiences interact with The Walt Disney Company. The mission is creating the ‘digital front door’ that unites all of Disney’s magic into a new interactive universe.

Disney Digital Entertainment is seeking talented individuals passionate about pushing the boundaries of game engine technology. As a critical part of our team, you will leverage your expertise to build and optimize feature-rich engines, ensuring smooth and high-performance experiences for global audiences.

This role will report to the Director of Engineering, Game Engines. The team is fully remote across the Nordic region.

What You Will Do

Drive Unreal Engine and UEFN Development

Use your deep experience with Unreal Engine to build and extend the systems that game teams rely on. You will work across Unreal Engine and UEFN, help shape the technology platform that game teams build on, and identify where it needs to go next.

Versatile Senior Programmer (C++, Verse, Python & More)

Write clean, maintainable code in the language best suited to the problem. You will move between C++ for engine and tools work, Verse for UEFN, and Python for automation and internal tooling, solving practical problems across the stack.

Core Systems Contributor

Lead improvements across the core systems that underpin Unreal Engine and UEFN development at Disney. Contribute directly and help teammates make development faster, smoother, and more enjoyable.

Tools and Pipeline

Build and evolve the internal tools that game teams depend on, including developer workflow automation, pipeline improvements, and source-control infrastructure.

AI-Empowered Development

Use AI coding tools in your daily work and help push the boundaries of what is possible. The team actively invests in leveraging AI to improve workflows and expects senior engineers to contribute to raising the bar.

• You see good documentation as part of delivering a complete solution. You take ownership of your work and make sure others can build on and maintain it, documenting systems, decisions, and workflows clearly so teammates can understand what has been done and why.

• Work closely with engineers, designers, and producers. Be part of creating a supportive, cross-functional environment. Share ideas, provide technical guidance, and help grow the team’s skills.

Required Qualifications & Skills 

Experience & Technical Expertise
You have significant professional experience with C++ and Unreal Engine, and a broad background across engine and tools development, systems refinement, feature implementation, and workflow optimization. You understand how pieces fit together across a tech stack, not just the parts you are directly working on.
Curiosity & Exploration
You are curious, eager to learn, and always up for experimenting with new ideas and approaches. You ramp up on unfamiliar domains using documentation, AI tools, and your teammates, rather than waiting for formal training.
Team-Oriented Mindset
You enjoy collaborating across disciplines, mentoring others, and supporting teammates to keep projects moving smoothly. The team is small, so mutual support matters.
Clear Communicator
You are comfortable sharing ideas, providing updates, and explaining technical concepts to engineers, designers, and stakeholders.
Strategic Problem-Solver
You take initiative, identify opportunities early, and are comfortable turning a rough direction into a delivered outcome. You thrive when you can shape the plan, not just execute one.
