Bachelor’s degree in engineering (Electrical, Mechatronics, Automation or related).

System-level troubleshooting across PLC, vision, robotics, motion control and smart devices.

Working knowledge of PLC platforms (Beckhoff TwinCAT, SAIA) and LabVIEW for diagnosis, tuning and minor adjustments — not new development.

Robotics and integrated automation systems.

Industrial protocols and networking (e.g., EtherCAT, Modbus), HMI / SCADA and motion control.
