Senior Technical Project Manager (Mobile App – Subscription Platform) - Contract to Hire

About the Project

We are building a native iOS and Android mobile application for a large, existing subscription-based digital platform.

The app will integrate with a highly customised backend system, support free trials, recurring subscriptions, entitlement-based access, in-app purchases, and secure content viewing.

This is a production-grade system, not a prototype or MVP.

We are working with an external mobile development agency and are seeking a senior, hands-on Technical Project Manager to own delivery from initial scope through public launch.

delivered on time and on budget

technically sound and scalable

compliant with Apple and Google app store policies

fully aligned with a subscription business model

thoroughly tested before launch

You will manage all communication with the mobile agency, coordinate backend/API requirements, own QA and UAT, and drive the project through to successful public release.
