Data Scientist (Quant Focus) | €70,000 – €90,000 | Madrid (5 days onsite)
You'll be joining a well-established, data-driven business that is investing heavily in its quantitative and modelling capabilities.
They operate at scale, with large, complex datasets at the core of decision-making across product and commercial functions. The focus is on building robust, production-grade models that directly influence strategy, not just offline analysis.
The team sits close to both engineering and business stakeholders, meaning the work you do is visible and used. There's a clear push towards more advanced modelling, better experimentation, and stronger foundations across data.
If you're someone who leans heavily into maths, modelling, and solving hard problems properly, this is a strong environment to do it.
