Job Description:

Core Systems Engineer

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 experience with Unreal Engine to build and extend systems, supported by a collaborative team. 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 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

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

Tools and Pipeline

Build and evolve internal tools, 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 engineers to contribute to raising the bar.

Write clear, useful documentation that helps others understand and build on your work. It is a key part of keeping the team moving forward.

Work closely with engineers, designers, and producers. Be part of creating a supportive, cross-functional environment. Ask questions, share ideas, and grow your skills as part of the team.

What You Bring

Experience & Technical Expertise
You have professional experience with C++ and Unreal Engine, and a 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. For this role, experience with C++ and Unreal Engine is required; experience with Verse, Python, other languages, or other engines is a plus.

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, learning from teammates, and supporting others 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.

Practical Problem-Solver
You take initiative, identify opportunities early, and are comfortable turning a rough direction into a delivered result. You enjoy helping shape the plan, not just executing one.

Background
Whether you studied computer science or learned on the job, what matters most is your ability to contribute, collaborate, and grow.
