We're looking for experienced Integration Developers to join our team.

The goal of the project is to automate the production of advertising newspapers.

Surrounding systems to be connected, all on the client side:

• Advertising system — delivers order data as XML plus print PDFs via a file transfer into an S3 bucket; also holds the insert allocation plan per distribution district.

• Client AI pipeline — for short local texts, delivers the editorial content.

• Cinema & event data sources — provide additional local content.
