Senior Embedded C++ Software Developer (вакансія неактивна)

We are looking for a Senior Embedded C++ Software Developer for our German Client — a leading full-service provider of solutions for the public transportation industry. The company supplies individual components and integrated system solutions from one source. You’ll become part of the team which develops a back-end API for the ticket management system for the public transport sector.

This applies to operating data, master data, device parameters, and billing data. The data stored in applications cannot be used by the front-end devices in this form. Device data must therefore be prepared before data transfer.

• Build UIs using Qt for embedded devices
• Apply robust communication security and cryptography practices
• Conduct unit, integration, and system testing; troubleshoot hardware/software integration issues
