The Senior Gameplay Engineer develops and delivers gameplay features and game systems across internal projects and co-development partnerships. The role combines strong programming skills, systems knowledge and rapid prototyping experience to turn design ideas into reliable, maintainable gameplay.

The role will initially support an open-world fantasy survival-crafting title, contributing to gameplay implementation, prototyping and supporting systems. Responsibilities and project assignments will evolve as existing projects develop and new projects are commissioned.

Working closely with Design, Engineering, Art, QA and Production, you will take ownership of assigned gameplay features from initial investigation and prototyping through to implementation, iteration and final polish. You will draw on experience with Unreal Engine 5, Blueprints, Unity and custom engines to evaluate technical approaches and resolve development challenges.

The role requires independent problem-solving, clear communication and a collaborative approach, alongside the ability to prototype ideas quickly and develop successful concepts into production-ready systems.

• Own the technical delivery of assigned gameplay features and systems from initial requirements through to implementation, testing and polish.
• Collaborate with designers to translate gameplay ideas into clear technical requirements and achievable development tasks.
• Build rapid prototypes to explore mechanics, validate assumptions and support design decisions.
• Develop gameplay functionality using C++ and Unreal Engine Blueprints, maintaining clear interfaces between code and designer-facing logic.
• Create maintainable systems that support iteration and integrate effectively with the wider game architecture.
• Refine gameplay through playtesting and feedback from Design, QA and other disciplines.
• Investigate and resolve gameplay defects, identifying underlying causes and verifying fixes with QA.
• Profile and optimise assigned gameplay systems to meet agreed performance requirements.
• Support build and integration troubleshooting where gameplay code or content affects development and testing.
• Contribute to code reviews, technical documentation and knowledge sharing, supporting consistent engineering standards.
• Communicate estimates, dependencies and technical risks, working with Production and discipline leads to manage delivery.
