The Experienced Gameplay Engineer develops and maintains gameplay features and supporting systems across internal projects and co-development partnerships. The role combines practical programming skills with experience in AI, multiplayer replication and console development to deliver reliable functionality that supports the player experience.

Working closely with Engineering, Design, QA and Production, you will take responsibility for well-defined features from implementation through to testing and refinement. You will draw on experience with Unreal Engine 5, Unity, custom engines and console platforms to investigate issues and deliver solutions within the project’s established architecture.

The role requires dependable technical delivery, clear communication and a methodical approach to problem-solving. You will also support colleagues through practical knowledge sharing and seek specialist guidance where work extends beyond your area of ownership.

• Communicate progress, estimates, dependencies and technical blockers to leads and Production.

• 5 years’ relevant experience in game engineering, including gameplay and supporting systems development.
• Proven ability to deliver well-defined gameplay features with appropriate autonomy and technical guidance.
• Practical programming skills in C++ and C#, with an understanding of maintainable software design and debugging.

• Awareness of console technical requirements and their implications for implementation and testing.
• Strong problem-solving, communication and collaboration skills.

• Experience developing gameplay for cooperative multiplayer, open-world or survival-crafting games.
• Experience using Unreal Engine Blueprints alongside native code.
• Experience investigating gameplay behaviour under latency or connectivity changes.
• Experience supporting console certification testing and resolving platform-specific defects.
• Experience creating reusable components or tools that improve gameplay development workflows.
