In this role, you will be an Android Application and Back-End Engineer, driving the development, certification, and operation of critical terminal features that connect our devices to the cloud.

What you’ll do:

• Core Systems Design: Designing and implementing complex solutions that span across Android applications, secure Inter-CPU communication, the Real-Time Operating System (RTOS), and payment kernels.
• Feature Integration: Adding critical payment features (such as dynamic currency conversion, mobile wallets, and offline payment support) to our existing products.
• Component Ownership: Taking end-to-end technical ownership of specific, mission-critical payment components on the terminal.
• Deep Troubleshooting: Troubleshooting and resolving highly complex issues that span the full device stack, from the Android application layer down to the embedded hardware/RTOS.
• Compliance & Certification: Working closely with international certification teams (e.g., EMVCo) and test organizations to ensure compliance and readiness.
• Collaboration: Working with Product Management to clarify and/or create technical specifications.
