We require an OpenImmo spec .xml feed to be created and then sent for verification by Immowelt. The person doing this job has to be fluent in English, which is our company language, and German, as the feed is being sent to a German service. Don't waste your time applying if you can't speak German.
Ideally we need someone with experience in this type of feed specification and someone who can take the error report from ImmoWelt and tailor the .xml to the exact requirements for verification
