This position offers the opportunity to work with cutting-edge technologies and contribute to the development of innovative products. The ideal candidate will have a strong background in C/C++ programming, experience with STM32 microcontrollers, and a solid understanding of embedded development toolchains and CI/CD systems. If you are passionate about embedded systems and enjoy solving complex technical challenges, we encourage you to apply.

Key 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, I²C, 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.

Required Skills & Qualifications

• 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).
• Experience with RTOS such as Segger embOS (must have) and Zephyr RTOS (nice to have).
• Knowledge of interfaces & communication protocols such as CAN, IO-Link, Modbus (TCP), EtherCAT / PROFINET / OPC UA, I²C, SPI, UART.
