We are looking for a Middle iOS Engineer to join our team and help build and maintain secure mobile app.
Project Idea
We are building a secure mobile app that enables volunteers to accept in-person donations for nonprofit organizations. The app integrates with a Deluxe’s Mobile SDK for payments (Apple’s Tap to Pay on iPhone) to process card-present transactions, supports offline storage and synchronization, and ensures donor and transaction data is securely routed through our backend (AWS-hosted). The iOS application is the primary focus for the first release.
What is the team size and structure?
You’ll be joining a growing team that includes a Senior Project Manager, Senior UI/UX designer, Senior Graphic Designer, Middle QA, working in close collaboration with the client.
