Role OverviewWe are looking for a Senior Unity Engineer to join our Ad Tech team in Barcelona, Spain. This role focuses on developing and maintaining scalable Unity libraries that support multiple games, including—but not limited to—monetization and ad technologies.

You will work closely with game teams to build efficient, reusable Unity tools and SDKs, improving development workflows and enabling seamless integrations. While familiarity with ad tech is a plus, experience in Unity SDK development and scalable library design is more important. The ideal candidate should be comfortable integrating third-party services (including ad networks) and optimizing performance across multiple titles.

Key Responsibilities

• Develop and maintain scalable Unity libraries and tools that support multiple game teams.


• Integrate and optimize third-party SDKs, including ad networks and other game services.


• Ensure high-quality, maintainable code by following best practices and design patterns.


• Collaborate with game teams to improve ease of integration and developer experience.


• Research and implement new features to enhance Unity SDKs and monetization capabilities.


• Support game teams in identifying and resolving issues related to SDK integrations.


• Conduct code reviews and write unit tests to ensure stability and performance.

Required Skills, Knowledge and Expertise

• Several years of experience working with Unity and C#.


• Strong understanding of Unity package development and SDK integration.


• Experience designing maintainable and scalable Unity libraries.


• Good knowledge of object-oriented programming principles and patterns.


• Experience with Git or other version control systems.


• Experience working with existing codebases.


• 
  Familiarity with native iOS/Android integrations is a plus, but not required.


• Excellent English skills, both written and verbal.
