Lead Frontend Engineer

Work Type: Full Time

SessionStack develops a Digital Experience Insights platform that defines the next step in digital analytics, enabling product teams to understand the user experience in their web products and find opportunities for improvements and optimizations.

SessionStack allows automatic data collection (instrumentation-fee analytics) and shows not only what happened to users, but also "why" it happened. This gives product teams the opportunity to quickly prove monetization hypotheses, analyze previously unsuspecting problems, and find entirely new possibilities.

The company is supported by the BrightCap Ventures Fund, the Estonian Wyse Guys Fund, as well as angel investors, established names in the IT community in Bulgaria, such as the creators of Telerik.
