Frequently Asked Questions
What does a senior ML engineer earn in Cologne?
Senior ML engineers earn €92,000–€130,000 base with a median of €105,000. Staff/Principal roles at DeepL can exceed €130,000. Head of ML/AI positions reach €120,000–€150,000+. After adjusting for Cologne's lower cost of living, real income rivals Munich senior ML roles.
How does DeepL pay compare to Berlin ML companies?
DeepL is competitive with Berlin's top tier. Senior ML engineers at DeepL earn packages that match or approach what top Berlin AI companies offer. The key difference: Cologne's 15–25% lower rent makes the take-home purchasing power significantly better. Staff/Principal at DeepL (€110K–€130K+) is exceptional for any location outside Munich.
What skills differentiate senior ML engineers in Cologne?
NLP and transformer architecture expertise is the highest-premium skill (DeepL effect). Production MLOps — model deployment, monitoring, A/B testing frameworks — differentiates engineers who can ship vs. those who only prototype. 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+). DeepL offers deep individual contributor paths (Staff/Principal) for those who prefer technical depth. RTL offers ML leadership for media/recommendation systems. The path is narrower than Berlin but each track is well-defined.
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. However, a strong production track record (deployed models at scale, MLOps expertise) can substitute for academic credentials at REWE Digital, RTL, and insurance companies.
