About the Role

We are looking for a Senior Software Engineer - Full Stack , based either in our offices in Paris, Barcelona or London, or remotely from France, Spain or the UK.

This role could sit within one of two lines: Interaction Analysis (In Page Analytics team - IPA) or Reliability & Performance Analysis - RPA , both currently looking for senior engineering talents.

- At IPA , we're at the forefront of user experience analytics. We process millions of website and mobile app sessions, extracting key performance indicators such as clicks, revenue, and engagement time. Our innovative platform then visualizes this data in two powerful ways: precise on-page numerical overlays and visually captivating heatmaps.

- RPA leverages AI algorithms to identify critical technical issues affecting users and business performance, such as crashes, errors, and slowdowns. By forecasting issue trends, effectively grouping related incidents, and pinpointing key correlations with user behavior data, RPA helps teams prioritize impactful problems. Insights are delivered through customized visualizations, APIs, and automated alerts, enabling efficient issue resolution.
