C++ UI Engineer

Our client is building an ambitious real-time interactive product and is looking for a senior-level engineer to take ownership of interface-related systems. This role focuses on the technical backbone behind menus, HUDs, flows, and player interaction layers, rather than visual design alone.

Start: ASAP

Length: 6 months with possible extension

Location: Must be in Stockholm 4 days per week

You will work hands-on with engine-level UI systems, shaping how information is presented, updated, and interacted with at runtime. The position blends low-level engineering with practical problem-solving in a fast-moving production environment. The project is developed using Unreal Engine and relies on a combination of native engine code, scripting, and editor-based workflows.

What you will work on

• Architect and extend interface-related engine systems

• Implement interactive screens, overlays, and presentation logic in Unreal

• Optimize UI-related code paths for real-time performance

• Improve internal workflows and tooling related to interface development

• Collaborate with engineers, designers, and usability specialists to support gameplay needs

• Ensure interface systems remain flexible and scalable throughout production

Technical background

• 5+ years of professional experience in game or real-time engine development

• Advanced C++ skills with experience in large codebases

• Practical experience working with Unreal Engine at a system level

• Experience implementing interface systems using engine-native solutions

• Strong understanding of performance constraints in real-time applications

• Fluent professional communication in English

What kind of person we’re looking for

• Enjoys solving structural and technical problems rather than only feature work

• Cares about code quality, longevity, and maintainability

• Comfortable taking ownership of complex systems

• Curious, analytical, and open to iteration
