• Work with hardware controllers, SDKs, and device communication protocols where required.
• Troubleshoot, debug, and resolve production issues to ensure system stability and performance.
• Improve code quality, performance, logging, and error handling.
• Collaborate with internal teams and vendors on technical implementation and system enhancements.
• Prepare and maintain basic technical documentation and support knowledge transfer.

Requirements

• Minimum 5 years of hands‑on software development experience.
• Strong experience in this core area: Android (Kotlin / Java), Backend (.NET C#), or Mobile (React Native).
• Solid understanding of RESTful APIs and backend service development.
• Experience working with existing / legacy codebases and extending them with new features.
• Good knowledge of TCP/IP networking and real-time or transaction‑based systems.
• Experience with databases and backend data handling.
• Ability to work independently and take ownership of system development.
• Good communication skills in English.

Preferred Skills (Added Advantage)

• Experience with vending machine systems, POS systems, or IoT‑related projects.
• Knowledge of hardware controller protocols or device communication.
• Experience with React Native (Android & iOS) or Android hardware integration.
• Familiarity with DevExpress, reporting tools, or operations portals.
• Experience in payment systems, remote monitoring, or high‑availability systems.
• Proficiency with GitHub (or similar version control systems such as GitLab/Bitbucket) for source code management, branching, and collaboration.
• Familiarity with cloud platforms (AWS, Azure, or GCP).
