Work in an international team. The R&D project focuses on communication and integration of devices with the cloud / IoT.Embedded software development includes, among others:• Creating software on the device that enables communication with the cloud – for example using MQTT, HTTP/REST, or WebSockets protocols.• Responsibility for collecting measurement data from the device, processing it, and sending it to the backend, as well as receiving remote commands.• Ensuring communication security, firmware protection, certificates, and encryption of data transmission.• Implementing consistent software updates for the device and the backend (embedded + cloud + front-end).Our expectations: Strong C++ programming ( object – oriented ), Embedded Linux development, SomeIP communication protocols, Testing frameworks: Google Test, Robot Framework, Agile development experience, Scrum, English or German proficiency Hybrid work from Katowice 70/30 ; 70% from home; 30% from the office. Work starts with two weeks of onboarding at the headquarters in Germany. After that, you will travel there once every quarter for a week for planning sessions. Main responsibilities:  Develop and maintain C++ based embedded software ( Embedded Linux ) for heating system control, Integrate with system architecture via SomeIP communication, Perform unit testing ( Google Test ), static code analysis and support system – level test ( Robot Framework and Python ), Work & collaborate in agile teams to meet sprint goals.
