Workplace Type : Onsite

About the Role :

We are seeking a highly motivated and skilled Embedded Software Engineer to join our dynamic team. In this role, you will be responsible for the development, maintenance, and optimization of embedded software for microcontroller-based systems. You will work closely with cross-functional teams to deliver high-quality, reliable, and innovative solutions.

This is an excellent opportunity to contribute to cutting-edge projects and advance your career in a challenging and rewarding environment. The ideal candidate will possess a strong background in C/C++ programming, experience with STM32 microcontrollers, and a solid understanding of embedded systems principles. You will also be involved in setting up a Linux-based toolchain and training colleagues, contributing to the continuous improvement of our development processes.

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, 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).

- 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 and communication protocols such as CAN, IO-Link, Modbus (TCP), EtherCAT / PROFINET / OPC UA, IC, SPI, UART.

- Understanding of security concepts like Secure Boot & Secure Firmware Update (SFI/SFU), TrustZone for Cortex-M33, and AES-256 & SHA-512 Hardware Encryption.
