EU AI Act compliance (explainability, fairness, audit trails) is an emerging premium skill, especially for insurance ML.
Is there a Head of ML career path in Cologne?
Yes. Insurance companies (AXA, Gothaer) and REWE Digital offer the clearest paths to Head of ML/AI roles (€120K–€150K+).

How important are academic credentials at the senior ML level?
More important than at junior levels. An MSc in ML, statistics, or computer science is expected. DeepL's research-adjacent roles prefer PhDs, especially for core NLP/translation research.
