In most cases, anyone applying for a permit online to work in Sweden will not need to visit a Swedish embassy. If it turns out you need to visit a Swedish embassy you should turn to one of these, if you are lawfully residing in the Schengen area:

The Swedish Embassy in Athen
The Swedish Embassy in Berlin
The Swedish Embassy in Madrid
The Swedish Embassy in Paris
The Swedish Embassy in Rome

The Swedish Embassy in Tallinn does not accept applications or handle migration cases.
