• Maintain and enforce UI coding standards, best practices and documentation.
• Give meaningful feedback on all aspects of the game by being an advocate for players at every possible opportunity.

• NOT be encouraged to crunch or work overtime.

Ideally You'll Have:

• Deep experience with Unreal Engine (UE5 preferred)
• Strong technical background with scripting languages.
• 3+ years as a professional developer in video game UI implementation, preferably on a shipped title.
• Experience integrating UI with gameplay systems (e.g., inventories, progression, matchmaking).
• Experience implementing UI animation, transitions and motion using Unreal’s tooling.
• Strong self-motivation and self-sufficiency. You know how to independently implement large changes and find the resources you need to make your vision clear to the team.
• Excellent communication skills and be a proactive communicator. You’ll be able to speak deeply with other engineers as well as presenting ideas in appropriate depth to non-coders.

Bonus Points:

• Experience writing custom Slate widgets or working directly with Unreal’s Slate framework.
• Comfort profiling and optimizing UI performance.
• Exposure to console development or multi-platform UI requirements.
• Interest in mentoring junior engineers.
