About Studio SirensFounded in 2024 under Snail Games, Studio Sirens is a development team focused on prototyping innovative gameplay systems, crafting bold new IP, and co-development projects. Blending technical precision with narrative ambition, the studio brings immersive worlds to life through a gameplay-first approach, supporting major releases while forging its own creative path within the Snail Games portfolio. About the RoleWe recently released an expansion for an existing UE5 product; the next phase is to transition the expansion into a fully-fledged standalone product. We are seeking a Gameplay Engineer with strong Unreal Engine experience to support the transition effort from expansion-based integration to an independent, stand-alone, commercial game experience. This role focuses on implementing improvements to gameplay systems, assisting with architectural adjustments required for independent operation, and contributing to stability and polish as the title transitions into a standalone product. You will work closely with senior engineers and designers to support targeted efforts to improve the player onboarding experience and balance gameplay to broaden audience accessibility while preserving the IP’s core identity. The ideal candidate is fluent in both C++ and Blueprints, understands best practices, and thrives in a collaborative, fast‑moving production environment.
