* Implement interfaces for retrieving information from applications.

* Support actions such as search, create, update, send and delete.

* Develop reusable integration interfaces and SDKs.

* Handle authentication, authorization and permissions.

* Investigate third-party application integration limitations.

* Work with Android engineers on system-level application access.

Requirements

* Strong software engineering and API development experience.

* Experience integrating multiple applications or external services.

* Understanding of mobile application architecture.

* Experience with authentication and authorization.

* Strong debugging and integration skills.

* Experience building reliable APIs and asynchronous workflows.

Nice to have
