We’re looking for a Data Scientist who’s passionate about turning complex data into actionable insights — and isn’t afraid to dive into the world of data pipelines when needed.
If you're skilled in building and validating machine learning models, exploring large datasets, and want to collaborate with engineers and analysts on real-world problems — we’d love to meet you.
Beyond the technical work, you’ll work with internal stakeholders to turn their ideas and challenges into concrete, data-driven solutions. And when it’s time to share results, you’ll be able to explain your findings clearly and effectively — whether you’re speaking to product managers, analysts, or anyone else who needs to understand the impact.
If you’re excited about applying your ML skills in a practical, business-oriented context — and you enjoy jumping between data, code, and communication — we’d love to hear from you.
