• Are structured and systematically, holds strong written documentation skills and communicate well in Danish and/or English
• Might have an interest in industrial systems such as PLCs, SCADA or HMI and are familiar with cybersecurity standards, technical documentation or risk assessments, will be an advantage although it is not required.
