Senior Integration Engineer

We’re looking for a Senior Integration Engineer to help us scale ad technology across some of the most popular mobile games in the world, supporting integration flows, testing pipelines, and developer experience for King studios.

You’ll join the Integration team, the group responsible for ensuring that ad features are easy to adopt, well-tested, and built into games with confidence. This includes maintaining the integration layer, supporting the studios, and working closely with SDK, Product, and QA teams to troubleshoot issues and ship clean code across platforms.

This is a great opportunity for engineers who enjoy working across systems, debugging tough issues, and building tools and sample apps that help other developers succeed. You’ll be working at the intersection of SDK development, game studios, and platform team, helping scale a multi-platform ad integration strategy across King titles.

• Support the integration of the Ads SDK in mobile games (iOS, Android, C++, Unity)
• Maintain and evolve our integration tooling, including internal libraries and multiple sample apps (C++, Unity)
• Work closely with SDK engineers, QA, and game teams to define integration workflows and ensure features work as expected
• Investigate production issues and help teams debug, fix, and ship quickly
• Continuously improve our documentation, release validation, and developer support tools

• Strong experience in C++ development
• Familiarity with mobile platforms and build environments (iOS, Android)
• Experience integrating 3rd-party SDKs or working on mobile game tooling
• Clear communication skills and comfort working across teams, including engineers, QA, and external game studios
• Ability to write and maintain high-quality, testable code
• Willingness to dive into debugging, validation, and tooling, not just new feature development

• Unity development experience (C#)
• Familiarity with ad tech or mobile game development
