About the project:
We’re looking for a hands-on, self-sufficientPython Engineer to join a long-term product collaboration with an established European investment company. The company has been successfully managing multi-billion euro assets for 30+ years and is now actively investing in AI-driven innovation.
You'll work closely with a highly professional internal team — analysts, portfolio managers, and risk experts — to bring modern, impactful solutions into their everyday operations.

-
Experience with SFTP, SharePoint, or other enterprise integrations.
-
Experience integrating with PowerPoint, Excel, or working with Power Queries.
-
AI is used as part of the daily engineering routine — e.g., for troubleshooting and root-cause analysis — so hands-on experience with AI tools is a plus, and any background in AI integration is welcome, though not required.
