• Performing code reviews and ensuring the overall quality of the game codebase.

• Troubleshooting and optimizing existing systems to improve game performance across platforms.

• Working in a scrum/agile environment, ensuring features and systems are delivered on time and with high quality.

What we will need from you

• Experience in game development, with a focus on Unreal Engine and gameplay system development.

• At least two shipped titles, preferably with large or open-world gameplay systems.

• Strong software engineering background with expertise in architecting scalable, modular systems.

• Proficiency in Unreal Engine 5, with hands-on experience using C++ and/or Blueprints.

• Experience with Lua scripting or similar scripting languages, especially in the context of gameplay programming.

• Proven leadership skills, including experience mentoring, managing, or guiding a team of developers.

• Ability to write clean, maintainable, and high-performance code.

• Excellent communication skills, both written and verbal.
