• Supporting commissioning, both in-house and at customer sites
• Collaborating with commissioning engineers and the wider team

• 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
• Communicative English (B2 or higher) mandatory and German as an advantage
