What we offer
• Remote work, long-term project with a German product team
• A role where AI-driven development is the standard way of working, not an experiment

What Success Looks Like

You are someone who can take an ambiguous data or intelligence problem, understand the underlying business requirement, and design a robust technical solution.
 

You should be comfortable moving between system architecture, data pipelines, backend development and applied AI, rather than specialising exclusively in one layer.
 

We value engineers who question assumptions, investigate problems deeply, take ownership of outcomes and can make pragmatic engineering decisions without over-engineering.

We are looking for someone capable of owning significant technical areas independently and helping shape engineering decisions as the platform evolves.
