The Gameplay Engineer supports the implementation and maintenance of gameplay features, game systems and supporting integrations across internal projects and co-development partnerships. The role combines practical programming skills with experience in backend services, data management and development tools to deliver reliable, maintainable functionality.

The role will initially support a shared-world multiplayer adventure, contributing to gameplay systems and their connections to supporting tools and services. Responsibilities and project assignments will evolve as existing projects develop and new projects are commissioned.

Working closely with Engineering, Design, QA and Production, you will implement scoped gameplay features, investigate defects and support the data flows and integrations that underpin player-facing functionality. You will also draw on experience with backend user accounts, JSON serialisation, user-generated content data management and development workflows.

The role requires clear communication, a methodical approach to problem-solving and the ability to deliver agreed work while seeking technical guidance where appropriate.

• Implement and maintain scoped gameplay features and game systems in line with agreed designs and coding standards.
• Collaborate with designers and other engineers to translate gameplay requirements into achievable implementation tasks.
• Connect gameplay features and UI functionality to underlying game data and supporting services.
• Develop and maintain integrations between game systems, backend services and internal tools.
• Support user account functionality and associated data flows, following project requirements for data handling and access.
• Implement and maintain JSON serialisation, deserialisation and validation for structured game and service data.
• Support systems for storing, retrieving and managing user-generated content data.
• Contribute to development tools, automation and DevOps workflows that improve integration and delivery.
• Investigate, reproduce and resolve defects, working with QA to verify fixes and check for regressions.
• Write maintainable code, participate in code reviews and document relevant systems and workflows.
• Communicate progress, dependencies and technical risks, escalating complex issues to senior engineers when needed.
