Embedded Software Developer | RTOS | CAN | ARM | IEC61508 | Functional Safety

Firmware development of a universal receiver for radio remote controls across various application domains.

The receiver control unit translates control signals from the remote control to the facility or vehicle on which the receiver is installed, doing so in a manner understandable to the respective facility or vehicle. 

• Development of a requirement specification
• Creation of an action plan to make the software and hardware development certifiable for SIL3
• Design of a software architecture for the receiver, using a state-of-the-art real-time operating system approach
• Establishment of a development-supporting test environment for the firmware, as well as a test plan for the final validation activities
• Implementation of the firmware according to the action plan and requirement specification
• On-site integration and support for end customers
