Marfeel is a fast-growing SaaS company transforming the way digital publishers understand and grow their audiences. Our real-time analytics and activation platform empowers newsrooms and content teams to make data-driven decisions that drive engagement, loyalty, and revenue.
Headquartered in Barcelona with a globally distributed team representing over 15 nationalities, we're proud of our diverse and collaborative culture. Our people are the driving force behind our innovation—and we're just getting started.
We're hiring a Data Insights & Investigation Specialist who blends sharp investigation with clear storytelling. You'll partner with leading publishers such as Business Insider, El País, McClatchy and Webedia to make sense of the 100+ billion data rows we ingest every day.
You'll bring clarity to our data by analysing how our metrics relate to external sources, explaining any relevant differences (methodology, taxonomy, tracking, attribution, timing), and coordinating with stakeholders on actions and follow-up checks.
In parallel, you'll turn trusted data into narratives: mining large, multi-source datasets to surface trends and angles, then crafting publishable reports, benchmarks, and deep dives that Marketing, Sales, and Customer Success can use externally.
