Job description

Our client, an international energy company, is looking to strengthen its development team by hiring an experienced Senior Embedded Software Engineer C++ (m/f/d) with experience in IoT environments. This is a direct permanent position with the option to work remotely, living in Germany (work Visa).

Your Responsibilities

• Develop and take technical ownership of modern C++ applications and system services running on Embedded Linux.
• Further develop modular multiprocessor firmware architectures, including a shared-memory process model, asynchronous applications, state machines, and IPC (Inter-Process Communication).
• Work on core runtime components such as firmware core services, configuration management, event processing, data logging, and component discovery.
• Build, flash, configure, and debug firmware on real target devices and test benches.
• Maintain CMake-based build systems and develop automated unit, module, and system tests.

Your Qualifications

• University degree in Electrical Engineering, Computer Engineering, Computer Science, Technical Computer Science, or a comparable technical discipline.
• At least five years of professional experience in Embedded Linux software development or a comparable position.
• Strong practical experience in developing and debugging software on Embedded Linux devices.
• Professional experience with modern C++, including C++17/20/23.
• Experience in developing or maintaining modular firmware architectures – not just implementing new features within an existing framework.
• Good knowledge of Linux system programming, particularly processes, concurrency, shared memory, IPC, and asynchronous processing.
• Solid experience with automated testing at unit, module, and system level. Experience with simulators or Hardware-in-the-Loop (HIL) test environments is a strong advantage.
• Experience with CMake, cross-compilation, target-system debugging, and CI/CD.
• Ability to take technical ownership and clearly explain architectural decisions.
• Experience with Yocto, Modbus, RS485, SunSpec, MQTT, Secure Boot, and the implementation of signed updates.
• Very good English skills; German language skills are a plus.
