The impact you will create:
You accompany internal IT/OT products from the initial architectural concept through prototyping to production-ready integration in the plants.
You analyze and break down complex technical matters – whether at the protocol level, in the Linux kernel, or when integrating intelligent sensors.
You connect classic automation (PLC, fieldbuses) with modern software practices.
You evaluate edge hardware, configure (real-time) operating systems, and ensure a high-performance, secure connection to higher-level IT systems.
You test new technologies (e.g., vPLC, RT-Linux, IIoT protocols) for their practical viability and translate them into scalable standards.
Experience and skills you will need:
A completed degree (e.g., Computer Engineering, Automation Technology, Electrical Engineering) or a comparable qualification in the IT/OT environment.
Initial experience with industrial control technology, fieldbuses, or sensors/actuators.
Knowledge of Linux environments (ideally real-time Linux / PREEMPT_RT), shell/scripting, or system architectures at the field level.
Basic knowledge of a modern programming language (e.g., Python, C/C++, Go, or Rust).
You possess the ability to methodically break down complex systems, get to the root of causes, and build pragmatic, robust solutions.
You communicate confidently in written and spoken German and English.
