We are looking for a Senior iOS Developer with strong expertise in native SDK development to join the AdTech project. In this role, you will contribute to the development and maintenance of production-grade mobile advertising SDKs used by publishers worldwide.

You will work with release-critical iOS SDK products distributed through CocoaPods and integrated into third-party mobile applications. The project requires deep understanding of SDK architecture, release processes, stability, and integration support rather than standard mobile application development.

We at Sigma Software offer the opportunity to work on technically challenging products, collaborate with experienced engineering teams, and contribute to high-scale mobile monetization solutions used in real production environments.

Клієнт

Our Customer is a technology company operating in the mobile advertising industry and focused on building scalable in-app monetization solutions. The company develops mobile advertising SDKs for iOS and Android platforms that are integrated into publishers’ applications and support multiple ad formats, tracking systems, and communication with advertising infrastructure such as SSPs and ad servers. The environment is highly quality-oriented due to the production-critical nature of SDK releases and external integrations.

Проєкт

The project is focused on the ongoing development and maintenance of existing open-source iOS SDKs that serve as a core part of the Customer’s in-app advertising infrastructure. These SDKs handle ad rendering, timeout management, tracking beacons, and communication with ad-serving systems while abstracting technical complexity from publishers integrating the solution into their applications.

You will participate in feature development, SDK architecture improvements, release management, and integration support while ensuring high stability and backward compatibility across supported iOS environments.

Key Technologies: Swift, Objective-C, CocoaPods, iOS SDK, Automated Testing, Mobile Advertising Technologies.
