Job Description

Your Responsibilities

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

Your Profile

Degree in Computer Science, Electrical Engineering, or equivalent qualification. Strong proficiency in C and C++, preferably in embedded software development. Experience in STM32 microcontroller families (especially Cortex-M0+, M4, M33). Experience with embedded development toolchains, IDEs (CLion, VS Code), and CI/CD systems. Familiarity with Unit-Test frameworks (e.g., Google Test). Solid understanding of schematics, technical datasheets, and reference manuals. Strong proficiency in Linux OS. Open-minded, structured, independent working style and strong team player. Good communication skills in English (German is a plus).
