Senior Staff Network Security Engineer

Internal Corning Employees are provided the opportunity to review global job openings for potential interest. However, they are encouraged to do so with the understanding that whether or not they will be considered a candidate for positions located outside their geographic area (city, country, region) will depend on a number of factors such as the availability of local subject matter expertise or qualified talent, the need to obtain and availability of work authorization, costs associated with internal transfer, etc. It will be the decision of the hiring organization whether to permit employees applying outside the local area where the opening exists to be considered a candidate for that opening. It is recommended employees wishing to apply for job openings at Corning make their supervisor aware of their interest before formally applying.
