Brief Description

Job Description:

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.

Preferred Skills

Soft Skills

· Open-minded, willing to learn, and forward-looking attitude.

· Curious, questioning the status quo, and proactive in sharing ideas.

· Analytical thinking and structured approach.

· Team-oriented with a security-focused and test-driven development mindset.

Motivation & Role Impact

You will contribute to the core embedded systems framework by implementing the complete hardware abstraction layer. Your work will enable application developers to access microcontroller features more efficiently and will support a highly modular and reusable software environment across product lines.
