ISOCHRONIC AG is looking for a Motion Control Engineer with strong expertise in real-time C programming to develop the core motion logic of our industrial robotic systems. Your primary responsibility will be to design and implement high-performance C motion software running inside our TwinCAT-based automation platform. You will work at the intersection of real-time control, robotics, machine safety, and industrial communication.
Responsibilities
* Main Responsibilities – C Motion Software
o Develop real-time C modules running in TwinCAT for:
+ Multi-axis synchronization
+ Macro-operations requiring deterministic execution
+ Kinematics transformations
o Define and implement MQTT communication
o Design and optimize interfaces between C code and the Beckhoff PLC layer
o Ensure deterministic timing, robust error handling, and safe behaviour of the motion software
* Additional Responsibilities – Beckhoff/TwinCAT & PLC
o Set up complete TwinCAT3 environments
o Configure and commission EtherCAT networks: drives, distributed I/O modules, and sensors
o Tune servo and induction motor drives and validate axis performance
o Design and implement the machine's safety architecture (wiring concepts, safety functions, and safety logic)
Required skills & Experience
* Strong expertise in C programming for real-time or embedded systems
* Solid understanding of motion control principles and multi-axis coordination
* Experience with TwinCAT 3, Beckhoff PLCs, and EtherCAT-based architectures
* Good knowledge of servo drives, induction motors, and axis tuning
* Experience implementing machine safety concepts (STO, SLS, emergency stop chains, safe motion functions)
* Ability to commission complete automation systems autonomously
Profile
We are looking for someone hands-on, rigorous, and autonomous, capable of taking responsibility for the real-time motion software while also managing the Beckhoff environment and ensuring the entire motion system works.
Fluent in English. German and/or French are a plus.
Valid Swiss / EU work permit.
About Us
We move fast. We improve constantly. We’re a small team serious about both robotics and collaboration, and motivated by autonomy and responsibility. If that kind of environment energizes you, let’s build the next phase together.
