Pros

Good direct manager — approachable and proactive; open to feedback and keen to support improvements. Salary is competitive and aligned with market benchmarks.

Cons

Belgian hub doesn’t always feel central to company strategy — decisions and resources often appear focused elsewhere, which reduces local autonomy and visibility.
