A Snapshot of Your Day A critical vulnerability in a component we use has been published on the Internet. You analyse the actual risk in the context of our HVDC and FACTS systems and inform the affected customers. You then plan the next steps, from testing the security updates provided on our test field through to installation at the customer''s premises. In addition to day to day business, your focus will be on developing new security concepts, revising existing processes and advising external and internal customers. As part of a hybrid working method, you will work either in the office in Erlangen, on the test site in Forchheim or from your home office. During the summer months in particular, you will be working at various customer sites on certain days.
