The BE Management strongly supports the personal development of each staff member and has put in place an initiative called BE Internal Temporary Detachment. The idea is similar to Internal Mobility within the department, but limited in time. For a period of 1 to 2 years, the staff member may be "detached" to another group in the BE Department, after which he/she returns to his/her activities in the group. The activity and required profile for such a temporary detachment is described in a document similar to a vacancy notice.
If you are a BE Staff Member with a limited duration (LD) or indefinite contract (IC) and one of the opportunities on this list is of interest, you are encouraged to contact the Group Leader of the hiring group for more details.
Go for it!
