Embedded Software Developer

• Development and maintenance of embedded software in C/C++ for microcontroller-based systems
• Adaptation and optimization of existing product software
• 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.

• Programming and configuration of STM32 microcontrollers (Cortex-M0+, M4, M33)
• Implementation of device drivers, peripheral interfaces, and communication protocols (UART, SPI, I²C, etc.)
• 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
• 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
• C – hardware-based programming
• C++11 to C++17 or higher
• Python (used in toolchain and scripting)
• STM32H5 (ARM Cortex-M33, 250 MHz)
• STM32U5 (ARM Cortex-M33, 160 MHz)
• STM32F4xx
• STM32F103
• Cortex M0+, M4, M33 (general)
• Segger embOS (must have)
• Zephyr RTOS (nice to have for future development)
• JetBrains CLion, VS Code
• CMake, Make
• Jenkins
• Git, GitLab
• JetBrains IDEs, Upsource
• Jira Software, XRay
• J-Link Debugger (SEGGER)
• ST-LINK/V3 Debugger

• CAN (Controller Area Network)
• IO-Link
• Modbus (TCP)
• EtherCAT / PROFINET / OPC UA
• I²C, SPI, UART
• Secure Boot & Secure Firmware Update (SFI/SFU) – STM32H5 supported
• TrustZone for Cortex-M33 (secure/insecure application separation)
• AES-256 & SHA-512 Hardware Encryption
• ISO 61508 / IEC 62443 – Safety & Security Standards
