Frequently Asked Questions
What does a senior data scientist earn in Cologne?
Senior data scientists in Cologne earn €78,000–€115,000 base, with a median of €88,000. Lead/Principal roles at DeepL or REWE Digital earn €95,000–€115,000. Head of Data Science roles at insurance companies reach €105,000–€130,000+. NLP specialists at DeepL can exceed these ranges.
What is the difference between a senior data scientist and ML engineer in Cologne?
Senior data scientists focus on statistical modeling, research, and business insights — working closely with product and business teams. ML engineers focus on building production ML systems (model serving, pipelines, monitoring). In Cologne, ML engineers earn slightly more at median (€90K vs. €88K) due to production engineering demands. At DeepL, the distinction blurs: many roles require both research and production skills.
Is there demand for senior data scientists in Cologne?
Yes, but the market is more specialized than Berlin. There are fewer total senior DS roles, but less competition per role. Cologne's demand is concentrated in NLP (DeepL), retail analytics (REWE Digital), media intelligence (RTL), and insurance (AXA, DEVK, Gothaer). Each vertical has consistent, ongoing demand for experienced data scientists.
Should I move from Munich to Cologne for a senior data science role?
Munich pays more in nominal terms (median ~€91K vs Cologne's ~€88K), but Cologne rent is 35–45% cheaper. Purchasing power is often better in Cologne. The trade-off: Munich has a larger DS market with more employer diversity (automotive, industrial AI). If you specialize in NLP, media, or retail analytics, Cologne is compelling. For automotive or industrial ML, Munich is better.
What is the path from senior data scientist to leadership in Cologne?
Two main paths: (1) Technical leadership — Senior DS → Lead → Principal at DeepL or REWE Digital (€95K–€115K+), focused on technical direction and mentoring; (2) Management — Senior → Head of Data Science (€105K–€130K+) at insurance companies or REWE Digital, focused on team building and strategy. The insurance sector offers the clearest management path.
