• Providing technical cyber security support for testing, installation, commissioning, and service activities as well as executing them. 

• Preparing and maintaining project documentation, including as-built engineering deliverables. 

• Participating in customer and project meetings to resolve technical issues and meet contractual obligations. 

• Coordinating with project, supply chain, manufacturing, and testing teams to deliver solutions on time and within scope.
