Job description

Development and maintenance of embedded software in C/C++ for microcontroller-based systems.

1. Programming and configuration of STM32 microcontrollers (Cortex-M0+, M4, M33).
2. Implementation of device drivers, peripheral interfaces, and communication protocols (UART, SPI, I²C, etc.).
3. Adaptation and optimization of existing product software.
4. Software integration and testing on target hardware.
5. Conducting Unit-Tests and Code Reviews.
6. Driving and contributing to the test strategy.
7. Design and maintenance of the development ecosystem and CI/CD pipelines using GitLab/Jenkins.
8. Setup, maintenance, and continuous improvement of embedded toolchains (compilers, linkers, debuggers, build systems).
9. Optimization and integration of embedded IDEs (e.g., JetBrains CLion, VS Code) with appropriate plugins.
10. Evaluation and documentation of tools, and creation of development guidelines.
11. Collaboration with cross-functional teams (mechanics, electronics, testing, hardware).
12. Participation in setting up a Linux-based toolchain and training colleagues.
