It’s not obvious from the post: is the job position remote-friendly, or is it Berlin only?


Hello Dimitar,

the position will be in Berlin and we support relocation. Of course we are remote-friendly, during these times more than ever. Though we are not intending to become a remote-company.

I am happy to have a brief call with you to answer further questions, if you are interested.

Warm regards,

I am interested. Will contact you privately shortly.
