• Supporting commissioning, both in-house and at customer sites 

• Collaborating with commissioning engineers and the wider team 

• Adapting solutions based on customer requirements 

• Designing, testing and adjusting communication protocols of Sécheron systems and their integration into customers SCADA systems (no deep SCADA expertise required)   

Requirements

• High school / university degree in Automation / Programming/IT 

• Practical experience and knowledge of HMI/PLC  

• Ability to read electrical schematics and translate them into logic connections 

• Basic knowledge of industrial communication protocols and their use
